With deep-sea mining plans in limbo, Norwegian companies fold or dig in
- Norway’s plans to mine seabed minerals in Arctic waters remain in limbo after the first licensing round was delayed in December 2024. However, the government maintains that progress will resume soon, with a licensing round tentatively set for 2026.
- Some deep-sea mining companies have faced significant financial struggles due to the delay, with one company going bankrupt and another slashing costs; yet, other firms remain optimistic, insisting the industry’s future is still secure.
- Experts warn that considerable knowledge gaps must be addressed before deep-sea mining can proceed, particularly regarding environmental impacts.
- In Norway, the industry also continues to face heavy opposition from environmental groups, the fishing sector, and several political parties.
Even the Gulf of Aqaba’s ‘supercorals’ bleached during 2024 heat wave
- Scientists have long considered the corals in the Gulf of Aqaba in the northern Red Sea to be uniquely resilient to extreme temperatures.
- For the first time on record, however, the heat wave of 2024 bleached some of these super-resilient corals in Israeli and Jordanian waters, according to scientists.
- Scientists studying the episode’s severity and extent estimate that perhaps 5% of the corals in their study area in Israeli waters bleached during the oppressive Northern Hemisphere summer; a small fraction died, but most recovered over the relatively cooler months that followed.
- Tackling threats like pollution that could reduce the corals’ ability to withstand extreme heat is the best way to protect them from rising marine temperatures, and scientists say an oil terminal that sits barely half a kilometer from some of the “supercorals” poses an imminent threat.
Award-winning film highlights lasting damage from X-Press Pearl disaster in Sri Lanka
- “This Is Not a Pearl,” a short film by Sri Lankan filmmaker Tharindu Ramanayaka, uses a poetic narrative of a pearl oyster mistaking toxic plastic pellets, or nurdles, for her pearl to symbolize the environmental devastation caused by the 2021 MV X-Press Pearl disaster.
- The sinking of the MV X-Press Pearl off Sri Lanka’s coast released 1,680 metric tons of plastic nurdles, marking the world’s largest nurdle spill and triggering long-term damage to marine ecosystems.
- Scientific studies show that toxic chemicals from the spill continue to harm marine life, especially zooplankton like sea urchin larvae and copepods, threatening the broader ocean food web.
- Sri Lanka’s legal efforts for compensation, including cases in both Singapore, where the ship’s operator is based, and the Sri Lankan Supreme Court, remain unresolved; meanwhile, nurdles continue to wash ashore, requiring continuous cleanup efforts nearly four years later.
Indonesia bets on ‘reuse’ to curb plastic waste and build a circular economy
- Indonesia is promoting “reuse” as a key solution to its plastic waste crisis, with civil society and the Ministry of Environment launching a “reuse road map” to mainstream practices like refilling and returning containers, aiming to shift focus from recycling to more sustainable waste prevention.
- The country produces 7.8 million metric tons of plastic waste annually, with nearly 5 million tons mismanaged and more than 1 million tons ending up in the ocean, making Indonesia one of the top contributors to marine plastic pollution.
- Experts say reuse is more effective than recycling, but receives far less investment globally; activists warn that reliance on recycling, especially chemical recycling, allows continued plastic overproduction and worsens environmental damage.
- Expanding reuse can also boost the economy, creating jobs in packaging, logistics and cleaning services, while reducing plastic-related harm; however, it requires significant infrastructure, regulatory support and public awareness to scale up.
India’s fisherwomen getting left behind by blue economy policies
Women make up nearly half of India’s marine fisheries workforce, yet policies to strengthen the country’s blue economy are leaving women behind, reports contributor Priyamvada Kowshik for Mongabay India. India’s draft blue economy policy framework aims to significantly boost the contribution of marine resources to the country’s GDP, and at the same time improve the […]
2024’s top ocean news stories (commentary)
- Marine scientists and policy experts from nine international research and conservation institutions share their list of the top ocean news stories from 2024.
- Hopeful developments this past year include advancing innovations in mapping technologies, legal strategies and financial instruments to protect the ocean and greater inclusion of Indigenous peoples and coastal communities into high-level ocean planning.
- At the same time, 2024 was the hottest year on record as a result of climate change, surpassing 2023, and scientists declared the fourth global coral bleaching event, a major setback for the world’s coral reef ecosystems.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Electrochemical removal of ocean CO2 offers potential — and concerns
- Stripping seawater of carbon dioxide via electrochemical processes — thereby prompting oceans to draw down more greenhouse gas from the atmosphere — is a geoengineering approach under consideration for largescale CO2 removal. Several startups and existing companies are planning projects at various scales.
- Once removed from seawater, captured carbon dioxide can be stored geologically or used commercially by industry. Another electrochemical method returns alkaline seawater to the oceans, causing increased carbon dioxide absorption over time.
- In theory, these techniques could aid in carbon emission storage. But experts warn that as some companies rush to commercialize the tech and sell carbon credits, significant knowledge gaps remain, with potential ecological harm needing to be determined.
- Achieving the scale required to make a dent in climate change would require deploying huge numbers of electrochemical plants globally — a costly and environmentally risky scenario deemed unfeasible by some. One problem: the harm posed by scale-up isn’t easy to assess with modeling and small-scale projects.
‘Shifting baselines’ in Cabo Verde after 50 years of declining fish stocks
- In Cabo Verde, as in many low-income countries in Africa, the historical record of fish catch is incomplete, making it hard to know what’s been lost and what’s required to fully rebuild.
- In a new study, researchers interviewed fish workers to understand how catches have changed over the last five decades, finding evidence of a major decline in volume of catch and maximum size of key species.
- The study also shows that young fishers and fishmongers don’t fully realize the scale of the loss — a case of what scientists call “shifting baselines.”
- Fishing communities on the West African mainland tell a similar story of decline, pointing to the urgency of centering local knowledge when devising fisheries management and conservation policies.
Time for a ‘moral reckoning’ of aquaculture’s environmental impacts
Aquaculture is often promoted as a solution to declines in wild fish populations, and has outpaced the amount of wild-caught fish by tens of millions of metric tons each year. But it carries its own myriad environmental impacts, to the detriment of both humans and the ocean, says Carl Safina, an ecologist and author. He […]
After historic 2024 coral bleaching, hope remains for Mesoamerican Reef
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.
‘Tragic’ mass fish die-off devastates Amazon River channel amid historic drought
A mass fish die-off in Brazil’s Amazon River region has killed an estimated 20-30 metric tons of fish and other aquatic animals, following one of the worst droughts in Amazonian history. On the night of Nov. 12, fishers from the riverine community of Igarapé do Costa, near the city of Santarém in northern Brazil, began […]
Leaders fail to address overfishing near Europe at ‘fraught’ international meeting
- The North-East Atlantic Fisheries Commission (NEAFC) held its annual meeting in London Nov. 12-15.
- NEAFC is a regional fisheries management organization, a multilateral body that controls fishing in international waters; its remit includes certain fish stocks in the Northeast Atlantic, near Europe.
- Among these, mackerel and herring have been overfished for years, yet NEAFC member countries did nothing to address the issue at the meeting.
- NGO observers have criticized NEAFC and its members for failing to address governance issues they say led to the overexploitation.
India advances deep-sea mining technology in the Andaman Sea
- The National Institute of Ocean Technology recently conducted an exploratory deep-sea mining trial in the Andaman Sea.
- Even as the International Seabed Authority (ISA), is yet to finalize the mining code for commercial purposes, those with exploratory licenses have been conducting mining trials in international waters.
- The opposition to deep-sea mining, citing environmental impact, is also at an all-time high.
44% of reef-building coral species at risk of extinction: IUCN
Some 44% of the world’s warm-water, reef-building coral species are facing risk of extinction, according to the latest update by the IUCN Red List of Threatened Species. This is a significant increase compared to the last assessment in 2008, when a third were considered threatened. The latest assessment covers all known coral species that build […]
Mapping ‘gloop and mud’ sheds light on seabed carbon storage
- Two new reports showing the extent of carbon storage in the marine sediments around the coasts of Canada and the U.K. are helping to build the case for greater protection of the seabed, as part of efforts to mitigate climate change.
- They also highlight some of the threats to this underwater carbon sink, particularly sediment disturbance caused by bottom trawling, a fishing method.
- A new project funded by the U.K.’s Natural Environment Research Council is set to investigate whether or not continued disturbance poses the risk of turning the seabed into a source of CO₂.
Coral biodiversity hotspot at risk from fossil fuel expansion, report warns
- A new report warns that the expansion of oil, gas and liquefied natural gas projects in the Coral Triangle region in the Western Pacific risks unleashing more oil spills, direct damage to coral reefs, noise pollution and ship traffic, not to mention greenhouse gas emissions.
- More than 100 offshore oil and gas blocks are currently in production, and more than 450 additional blocks are earmarked for future exploration, according to the report. If these projects are approved, the production and exploration blocks would cover 16% of the Coral Triangle, an area the size of Indonesia, the report states.
- The report notes there is already overlap between oil and gas operations and critical conservation zones, including 16% of the Coral Triangle’s marine protected areas.
- The Coral Triangle is one of Earth’s most biodiverse regions, stretching across the waters of the Philippines, Indonesia, Malaysia, Papua New Guinea, Timor-Leste and the Solomon Islands. It’s home to 76% of all known coral species, as well as numerous endangered marine species.
‘Don’t call it the high seas treaty’: Ocean biodiversity risks being sidelined in new deal
The global treaty designed for the “objective of the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction,” adopted last year, has more recently gained an inaccurate, but popular, nickname, and lacks independent enforcement, according to some observers. Known officially as the BBNJ agreement (biodiversity beyond national jurisdiction), it has since […]
More krill fishing and no new protected areas for Antarctic seas after latest talks
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) held its annual meeting Oct. 14-25 in Hobart, Australia.
- The international body comprised of 27 members is charged with conserving marine life in Antarctic waters, an area that is changing rapidly due to human-caused climate change.
- In 2009, the CCAMLR pledged to create “a representative network” of marine protected areas in the Southern Ocean, yet negotiations over four proposed MPAs have been at a standstill for years, due to repeated vetoes by the Chinese and Russian delegations.
- Despite a year of interim negotiations, CCAMLR members failed again at the latest meeting to reach agreement on creating any new marine protected areas and rolled back regulation of the burgeoning Antarctic krill fishery.
Protecting coral reefs boosts fish numbers by 10%: Study
- New research has found that the protection of coral reefs has boosted the amount of fish they harbor by around 10%.
- The study used survey data from about 2,600 reefs with varying levels of protection from overfishing.
- The team then built a statistical model to predict what would have happened if all reefs had not been protected, and the biomass, or collective weight of the resident fish, dropped by more than 10%.
- The scientists note their findings demonstrate that protections like marine protected areas are working and that greater coverage could lead to even more gains in fish biomass.
Norway poised to sail past opposition with deep-sea mining licensing plans
- In June, Norway proposed 386 license areas in the Norwegian Sea for future deep-sea mining activities.
- During the ensuing three-month public consultation period, the government received more than 70 responses from various organizations and members of the public. The responses offered a mix of views: the majority opposed Norway’s deep-sea mining plans, a minority expressed support, and many across the board called for more research.
- One entity criticizing Norway’s plans is the country’s own environment agency, which argued that there’s a lack of knowledge to safely pursue deep-sea mining while protecting the marine environment.
- Norway’s government has stated that it intends to begin issuing licenses in 2025 with a view to starting seabed mineral exploitation in 2030.
Lab-grown corals resisted bleaching during Caribbean’s worst marine heat wave
- In 2023, the Caribbean Sea experienced unprecedented heat: Beginning in March, sea surface temperatures throughout the region ranged from 1°-3°C (1.8°-5.4°F) warmer than normal.
- This unprecedented heat brought the worst coral bleaching event in the Caribbean’s recorded history, bleaching 60-100% of some reefs, and killing many patches.
- A new study found that certain species of coral propagated in the lab and then outplanted to restore reefs in five countries showed few signs of bleaching despite the prolonged marine heat wave, faring better than wild corals or corals propagated from fragments.
The ocean ‘belongs to all of us’: Interview with Palau President Whipps
- The President of Palau, Surangel S. Whipps Jr., has been calling for a moratorium — an official pause — on deep-sea mining in international waters for more than two years now, and he continues to reiterate his position.
- Palau has banned deep-sea mining in its national waters, but Whipps says his country is calling for a moratorium, rather than an outright ban, on seabed mining in international waters since the ocean “belongs to all of us.”
- While plans are progressing to allow deep-sea mining to start in international waters — and in some countries’ national waters — Whipps says he believes the world is starting to understand the importance of the deep sea as a growing number of nations call for a moratorium.
Six months after first Houthi ship sinking, attacks slick Red Sea with oil
- Exactly six months ago, on March 2, the Rubymar, a cargo ship carrying fertilizer, heavy fuel oil and marine diesel, became the first ship sunk in a series of attacks by the Houthis, the Iran-backed Yemeni civil war opposition group.
- The ship continues to raise fears of damage to the marine environment when its cargo holds inevitably disintegrate, including oil slicks, algal blooms and “dead zones.”
- In the latest significant strike, on Aug. 23, Houthis hit the Sounion oil tanker carrying almost 1 million barrels of crude oil, which now poses a navigational and environmental threat.
- Ongoing ship strikes by the Houthis in response to Israeli actions in Gaza threaten Red Sea marine ecosystems, which are already subject to the operational oil spills of one of the busiest shipping lanes on the planet, and the livelihoods of the coastal communities dependent on them.
Not merely ‘exploration’: PNG deep-sea mining riles critics & surprises officials
- Deep Sea Mining Finance (DSMF), an obscure company registered in the British Virgin Islands, recently conducted an exploratory mining operation off the coast of New Ireland province in Papua New Guinea (PNG), according to civil society members and a government official’s statements to the media.
- Satellite-based vessel-tracking data show that much of this mining activity took place in and around a controversial project site known as Solwara 1, where mineral-rich hydrothermal vents are located.
- Critics say the operation was illegal and that DSMF’s activities flout two ongoing moratoria that should prevent deep-sea mining in PNG’s territorial waters. On the other hand, a national official has said the company operated within its rights to explore the deep sea for minerals.
- The operation appears to have caught many by surprise, including government authorities meant to oversee such activities.
$35m debt-for-nature deal aims to protect Indonesia’s coral reefs
- A $35 million debt-for-nature swap between Indonesia and the U.S. aims to conserve coral reefs in eastern Indonesia over the next nine years, with the funding offset by canceled sovereign debt payable to the U.S.
- Indonesian conservation groups and their international partners will implement ground programs to protect reefs in key areas, strengthen marine protected areas and support community livelihoods under the deal.
- While environmentalists welcomed the funding, some argued debt swaps were insufficient to address the larger environmental and development challenges faced by countries in the global south.
‘Trust needs to be rebuilt’: Interview with candidate to head U.N. seabed-mining authority
- Leticia Carvalho, a Brazilian oceanographer and international civil servant, is running for secretary-general of the International Seabed Authority (ISA), the regulator of deep-sea mining in international waters, at a pivotal time for the deep-sea mining sector.
- Carvalhos’s opponent is Michael Lodge, a barrister from the U.K. who has served as the ISA secretary-general for two terms and is running for a third as a candidate from Kiribati.
- The election will take place at the ISA assembly meeting in Kingston, Jamaica, between July 29 and Aug. 2, 2024.
- Carvalho told Mongabay she believes it’s time for a change in leadership due to the principles of geographic rotation and gender equality, but also because she believes the ISA needs improvement in its management and governance.
‘It is indeed our problem’: Interview with Mário Soares on Brazil’s mangroves
- Mário Soares, a professor of biological oceanography at Rio de Janeiro State University who leads the Mangrove Studies Center (NEMA), has spent more than 30 years studying Brazil’s mangroves, their role in climate change, the effects of oil spills and the importance of mangrove conservation.
- While mangroves fetch a lot of attention in conversations about carbon sequestration, Soares argues that they serve numerous purposes in mitigating climate change; they are also vulnerable to the effects of climate change and must be conserved so that they, in turn, can reduce the vulnerability of the coastal zone.
- Soares also says the carbon market doesn’t solve the problem, only the symptom, because it applies “the market logic,” which created the problem in the first place; meanwhile, we’re not reducing emissions.
- Soares recently spoke to Mongabay about the history and future of Brazil’s mangroves in a video interview.
In northern Spain, climate change is killing shellfish — and women’s livelihoods
- In Galicia in northwestern Spain, shellfish harvesting is traditionally women’s work.
- But the clams and cockles the shellfish pickers’ livelihoods depend on are increasingly harder to come by.
- Extreme weather events made more frequent and intense by climate change, including heat waves and torrential rain, threaten the four main shellfish species harvested in the region, and with them, the tradition that has been passed down through generations of women.
New approach to restore coral reefs on mass scale kicks off in Hawai‘i
- ʻĀkoʻakoʻa is a recently launched program aiming to restore a 193-kilometer (120-mile) stretch of coral reef along the west coast of Hawai‘i Island — one of the first to attempt restoration at a large scale.
- The project will identify individual corals with high thermal tolerance and other high-performance traits, then use them to breed genetically resilient coral larvae for release onto the reefs during natural spawning periods.
- ʻĀkoʻakoʻa is working with partners to reduce other stressors to the reefs, which can help corals be more resilient to rising sea temperatures, and drawing on Hawaiian traditional values of environmental stewardship.
- If successful, the project could provide knowledge for how to restore ailing reefs around the world suffering from an onslaught of human-driven thermal stress.
Efforts to save Cambodia’s coast tread water as fish stocks plummet
- Along the coast of Cambodia, illegal fishing is driving fish stocks toward collapse and fishing communities into poverty.
- The Cambodian government’s capacity for and will to counter fisheries problems are minimal, and several government fisheries reform efforts are off track or behind schedule.
- As one multimillion-dollar foreign project to bolster government capacity and revive Cambodian fish stocks comes to an end, another is just kicking off.
- Whether these efforts to salvage Cambodia’s coastal resources will pay off depends on a range of factors and actors, but so far the plans implemented haven’t been enough to stave off the impending collapse of marine fish stocks.
Fishers left with no land, no fish, in fire sale of Cambodian coast
- Coastal communities in Cambodia are facing a double threat, from land and sea, as developers evict them from their homes and farms, and trawlers encroach on their nearshore fishing grounds.
- Illegal fishing, chiefly embodied by rampant, unchecked trawling in protected and prohibited waters, has devastated fish stocks, trashed marine ecosystems and left coastal communities in dire poverty.
- At the same time, the land is being sold out from under them: Nearly half of Cambodia’s coast has been privatized since 2000, with a slew of new projects tied to politically connected wealthy investors announced in the last five years, displacing families and closing off access to the sea.
- This is the second part of a Mongabay series about challenges faced by Cambodia’s small-scale fishers along the coast.
Illegal fishing and land grabs push Cambodian coastal communities to the brink
KOH KONG, Cambodia — Join Mongabay staff writer Gerry Flynn as he embarks on a crucial investigation along Cambodia’s coast, uncovering the effects of illegal fishing and unchecked coastal development on local communities. In recent years, fish stocks in Cambodian waters have plummeted, leading to a dramatic decline in income for small-scale fishers. The primary culprits? […]
Small-scale fishers lose out to trawlers in race to catch Cambodia’s last fish
- On Cambodia’s coast, fish catches have dropped precipitously in recent years, and so have small-scale fishers’ incomes.
- Small-scale fishers say commercial trawlers have been illegally entering their fishing grounds, scraping the sea clean of life and, with it, their community’s ability to survive.
- Although fishers often blame foreign vessels, satellite data show Cambodian-, Thai- and Vietnamese-flagged trawlers making frequent illegal incursions into Cambodia’s protected waters, community fisheries or shallow inshore waters legally reserved for small-scale fishers.
- This is the first part of a Mongabay series about challenges faced by Cambodia’s small-scale fishers along the coast.
As catches fall, Sierra Leone’s artisanal fishers turn to destructive practices
- Sierra Leone’s fish stocks have been under severe strain in recent years due to intensive industrial fishing and a growing population of artisanal fishers, with fishers consistently reporting falling catches.
- This has triggered heightened competition for increasingly scarce yields.
- To secure their livelihoods, artisanal fishers have turned to unsustainable fishing gear, such as undersize-mesh nets, and target fish breeding and nursery grounds, disrupting the fish reproductive cycle.
- The crisis is fueled by the ready availability of illegal nets, weak law enforcement and widespread economic hardship.
As plastic talks wrap up in Canada, fishers in Indonesia count the costs
- Fishers in the Thousand Islands archipelago off the Jakarta coast have reported extensive economic losses due to the scale of plastic waste littering their seas.
- Declining catch volume and costly repairs to boat engines are cited as drags on productivity, with one fisher telling Mongabay that his family now earns less than a decade earlier.
- Negotiators convened by the U.N. hope to conclude an international agreement in November that would limit the hundreds of millions of tons of plastic produced around the world each year.
Fishing by dodgy fleets hurts economies, jobs in developing countries: Report
- A recent report gauged the economic damage done by fishing fleets with shady track records in five vulnerable countries: Ecuador, Ghana, Peru, the Philippines, and Senegal.
- It found that these fleets’ activities could be costing the five countries 0.26% of their combined GDP, leaving some 30,000 people jobless and pushing around 142,000 deeper into poverty.
- “The report emphasizes that the uncontrolled growth in global fishing has led to overfishing, stressing fish stocks and impacting communities and the oceans’ well-being,” one of the authors told Mongabay.
No protection from bottom trawling for seamount chain in northern Pacific
- A recent meeting of the intergovernmental body that manages fisheries in the North Pacific Ocean failed to confer new protections for the Emperor Seamount Chain, a massive and richly biodiverse set of underwater mountains south of the Aleutian Islands.
- Bottom trawlers plied the Emperors aggressively in the past, decimating deep-sea coral communities and fish stocks.
- A proposal by the U.S. and Canadian delegations at the meeting of the North Pacific Fisheries Commission (NPFC) would have temporarily paused the limited trawling that continues there today, but failed to reach a vote.
- The NPFC did pass a separate proposal to regulate fishing of the Pacific saury (Cololabis saira), a severely depleted silvery fish that Japanese people traditionally eat in the fall.
Annual ocean conference raises $11.3b in pledges for marine conservation
- The 9th Our Ocean Conference (OOC) took place in Athens from April 15-17.
- Government, NGO and philanthropic delegates made 469 new commitments worth more than $11.3 billion to help protect the oceans, which was lower than in previous years.
- While some conference hosts and attendees celebrated the many successes of the OOC, there was also a shared concern that decision-makers aren’t moving fast enough to secure a sustainable future for the global ocean.
Global coral bleaching now underway looks set to be largest on record
- Scientists say that coral reefs are currently undergoing a global bleaching event, with more than 54% of the world’s coral reef areas in the territorial waters of over 50 countries experiencing heat stress. According to one scientist, the percentage of areas dealing with bleaching-level heat stress “has been increasing by roughly 1% per week.”
- To assess the current bleaching event, scientists drew on satellite-derived sea surface temperature data and in-water measurements.
- Experts say the current El Niño, a phase in the El Niño–Southern Oscillation (ENSO) climate pattern, in combination with rising global sea temperatures, is responsible for the extensive coral bleaching.
- Mongabay interviewed scientists most familiar with coral reef bleaching data, and experts attending the 9th Our Ocean Conference in Athens, taking place from April 15-17.
Deep-sea mining’s future still murky as negotiations end on mixed note
- Between March 18 and 29, members of the International Seabed Authority (ISA), the U.N.-affiliated regulator of deep-sea mining activities in international waters, met for talks in Kingston, Jamaica.
- One focus of discussion was the ongoing revision of the regulations governing exploitation, which are still in draft form, but which member states are aiming to finalize by July 2025. Seabed mining activities could begin before then, as early as next year.
- ISA officials said “good progress” was made on the regulations. However, one NGO observer pointed out that there were “many areas where these negotiations have not progressed.”
- Delegates to the meetings also didn’t adopt either of two proposals to limit the ability of Greenpeace International to protest deep-sea mining activities at sea.
Japan prepares to mine its deep seabed by decade’s end
- Japan is one among just a handful of nations actively pursuing deep-sea mining within its own waters.
- The country aims to be ready to mine by the late 2020s and could be among the first nations to exploit the deep sea.
- The country has completed multiple small-scale mining tests that it claims are world firsts, and it positions itself as a global leader in the “sustainable development” of deep-sea mining.
- However, concerns about the environmental impacts of deep-sea mining have prompted widespread opposition to the practice, and one critic notes that Japan’s momentum may be too great to stop for any warning signs its research might raise.
Communities worry anew as PNG revives seabed mining plans
- Coastal communities in Papua New Guinea’s New Ireland province rely on the sea for their livelihoods and culture.
- But Solwara 1, a resurgent deep-sea mining project aimed at sourcing metals from the ocean floor, could threaten their way of life, community leaders and activists say.
- They also say they haven’t been properly consulted about the potential pros and cons of Solwara 1, and government and company leaders have provided little information to the public about their plans.
- A coalition of leaders, activists and faith-based organizations called the Alliance of Solwara Warriors is opposing the project in Papua New Guinea and abroad, and calling for a permanent ban on seabed mining in the country’s waters.
Fears of marine disaster loom after fertilizer-laden ship sinks in Red Sea
- The MV Rubymar, a cargo ship carrying about 21,000 metric tons of ammonium phosphate sulfate fertilizer, has sunk in the Red Sea following an attack by Yemen’s Houthi rebels, raising fears of an environmental disaster.
- In addition to the fertilizer potentially entering the ocean, the vessel is also leaking heavy fuel, which experts say will impact the marine environment.
- The Red Sea is known to harbor some of the world’s most heat-resistant coral reefs, which makes the sinking of the Rubymar particularly concerning.
‘Corals dying’ as yet more bleaching hits heat-stressed Great Barrier Reef
- Both aerial and in-water surveys have shown that the southern section of the Great Barrier Reef is undergoing extensive coral bleaching.
- Surveys have also shown “limited bleaching” in the northern part of the Great Barrier Reef.
- However, scientists and reef managers plan to conduct more air and in-water surveys to further assess the coral bleaching across all parts of the Great Barrier Reef.
- Scientists suspect but have not yet confirmed that a seventh mass bleaching event since 1998 is currently underway; the last mass bleaching event on the Great Barrier Reef happened in 2022.
PNG communities resist seabed mining: Interview with activist Jonathan Mesulam
- The government of Papua New Guinea appears poised to approve Solwara 1, a long-in-development deep-sea mining project in the country’s waters.
- However, PNG has signed onto several seabed mining moratoria, and scientists have urged caution until more research can determine what the effects of this practice will be.
- Proponents say the seafloor holds a wealth of minerals needed for batteries, especially for electric vehicles, and thus are vital for the transition away from fossil fuels.
- But coastal communities in PNG’s New Ireland province have mounted a fierce resistance to Solwara 1, arguing that it could damage or destroy the ecosystems that provide them with food and are the foundation of their cultures.
Annual South Pacific fisheries meeting nets bottom trawling controversy
- The annual conference of the South Pacific Regional Fisheries Management Organisation (SPRFMO), an intergovernmental body, took place in Manta, Ecuador, between Jan. 29 and Feb. 2.
- SPRFMO, which manages fisheries across the vast international waters of the South Pacific Ocean, made key decisions on bottom trawling, labor rights, observation of squid-fishing vessels and transshipment at sea, a practice that can obscure the origin of illegally caught seafood.
- In what was perhaps the most controversial outcome of the meeting, delegates failed to adopt a proposal to complete the implementation of rules passed last year that would have limited bottom trawling of vulnerable marine ecosystems, such as coral communities.
EU parliament expresses disapproval of Norway’s deep-sea mining plans
- On Feb. 7, members of the European Parliament voted in favor of a resolution that raises concerns about Norway’s intentions to begin deep-sea mining activities.
- Although the resolution doesn’t hold any legal power, experts say it sends a strong signal to Norway that it doesn’t have the European support it may be relying on.
- Norway’s foreign ministry said that it has taken note of the resolution, adding that, like its European partners, it is committed to “sustainable ocean management.”
- In January, Norway voted to allow deep-sea mining exploration to commence in its waters.
Study: Indonesia’s new capital city threatens stable proboscis monkey population
- A recent study warns that the ongoing construction of Indonesia’s new capital city on the island of Borneo could destabilize the population of endangered proboscis monkeys currently thriving in the area.
- President Joko Widodo has characterized the development as green and with a minimal environmental impact, but concerns have arisen over the potential threat to the nearby Balikpapan Bay mangrove ecosystem that’s home to proboscis monkeys and other threatened wildlife.
- Scientists have advocated for sustainable development practices and emphasized the importance of respecting local biodiversity while constructing the new city, Nusantara.
- Their recommendations include legal protection for affected areas, habitat restoration, and collaboration with local stakeholders to mitigate the environmental impact.
From exporting coral to restoring reefs, a Madagascar startup rethinks business
- After her father died, Jeimila Donty took over her family’s coral export business and shifted its focus to conservation, creating Koraï.
- Donty is part of a young “pro-climate” generation that’s keen to incorporate the environment into business models.
- Koraï plants corals in Madagascan waters on behalf of other companies as part of their corporate social responsibility (CSR) commitments.
- The business is ambitious and faces challenges, such as recruiting workers and a lack of political support.
Pakistan bucks global trend with 30-year mangrove expansion
- Around the world, mangrove forests have undergone a decades-long decline that is just now slowing to a halt.
- In Pakistan, by contrast, mangroves expanded nearly threefold between 1986 and 2020, according to a 2022 analysis of satellite data.
- Experts attribute this success to massive mangrove planting and conservation, as well as concerted community engagement.
- Many in Pakistan are looking to mangroves to bolster precious fish stocks and defend against the mounting effects of climate change — even as threats to mangroves, such as wood harvesting and camel grazing, continue with no end in sight.
Cambodia sea turtle nests spark hope amid coastal development & species decline
- Conservationists in Cambodia have found nine sea turtle nests on a remote island off the country’s southwest coast, sparking hopes for the critically endangered hawksbill turtle (Eretmochelys imbricata) and endangered green turtle (Chelonia mydas).
- It’s the first time sea turtle nests have been spotted in the country in a decade of species decline.
- Two nests have been excavated to assess hatching success; conservationists estimate the nests could hold as many as 1,000 eggs.
- Globally, sea turtle populations are declining, largely due to hunting for food and the animals’ shells, used in jewelry; other threats to sea turtles include tourism development, pollution and climate change.
Critics push for more transparency at RFMOs that govern high seas fishing
- Around 17 regional fisheries management organizations (RFMOs) manage fishing in international waters, or the “high seas.”
- Scientists and civil society members have long criticized these international bodies for failing the high seas; many of the stocks they manage are overfished, research shows.
- Critics cite opaque decision-making as a key reason for conservation failures, and they’re making an increasingly vociferous case for RFMOs to become more transparent, citing their oversight of shared public resources.
- RFMO representatives, while citing internal rules as well as a need for privacy to maintain open negotiations among parties, point to recent steps toward transparency.
Palau is the first nation to ratify treaty to protect high seas
- Palau has become the first nation to ratify the high seas treaty, which seeks to protect and manage ocean areas beyond national jurisdiction.
- At least two other nations, Chile and the Maldives, appear to be on the cusp of ratifying the treaty.
- A total of 60 nations must ratify the treaty for it to take effect.
2023’s top ocean news stories (commentary)
- Marine scientists from six international research and conservation institutions share their list of the top ocean news stories from 2023.
- Hopeful developments this past year include a monumental global treaty to protect biodiversity on the high seas and the regulation of international trade in 97 species of sharks and rays under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
- At the same time, 2023 was the hottest year on record, with widespread bleaching of corals in the Caribbean and Great Barrier Reef, and many more hot years forecast as humanity’s emissions of greenhouse gases that cause global warming continue.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
‘Really a sad day’ as Norway votes to allow deep-sea mining in Arctic waters
- Norway’s parliament has voted to allow deep-sea mining to commence in the Norwegian Sea, a move that has garnered criticism from scientists and environmentalists.
- While the Norwegian government insists that it can conduct deep-sea mining in a sustainable way, critics say these activities will put marine ecosystems and biodiversity at risk.
- Norway will open a 281,000-square-kilometer (108,500-square-mile) area of the ocean for deep-sea mining, which mostly falls along its continental shelf.
Farewell, Java stingaree: Scientists declare the first marine fish extinction
- In December 2023, scientists declared the Java stingaree (Urolophus javanicus), a species of stingray, extinct.
- It’s the first marine fish confirmed to have gone extinct due to human actions.
- Scientists know very little about the species, which they haven’t spotted since a naturalist purchased the specimen from which he described the species at a fish market in Jakarta in 1862.
U.S. auctions off endangered whale habitat for oil and gas drilling
- On Dec. 20, the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM) held a lease sale to auction off oil and gas drilling rights in the Gulf of Mexico.
- Environmental groups and the U.S. Interior Department had tried to postpone this sale due to concerns about protecting the critically endangered Rice’s whale, a species whose key habitat overlaps with the lease sale areas.
- Scientists estimate there are fewer than 50 Rice’s whales left, and that the primary threat to the species is the oil and gas industry.
- While the lease sale went through without any protections for the Rice’s whale, environmental groups continue to explore legal and political avenues to ensure the species’ survival.
Vast new MPAs are PNG’s first to be co-managed by Indigenous communities
- On Nov. 12, the government of Papua New Guinea declared two large new marine protected areas totaling more than 16,000 square kilometers (6,200 square miles) that reportedly triple the country’s marine area under protection.
- The announcement capped a six-year effort led by U.S.-based NGO Wildlife Conservation Society to consult with local communities about how to set up the MPAs to curtail the harvest of threatened species and restore the health of fisheries that people have depended on for generations.
- The NGO called the announcement “one of the first and most ambitious community-led MPA wins” since countries agreed last year to protect 30% of land and sea area by 2030 under the U.N. Convention on Biological Diversity.
- However, some observers note the potential problems that could arise from foreign-led conservation in an area experiencing poverty, conflict, and minimal government support, and there is widespread agreement that the MPAs’ success will depend on securing financing for enforcement.
Did the tides turn for oceans at COP28? Climate summit draws mixed reviews
- The ocean featured in many negotiations around the climate crisis at the U.N. climate summit known as COP28, which took place in Dubai between Nov. 30 and Dec. 13.
- The final version of the global stocktake (GST), which served as the main agreement for COP28, referred to the importance of protecting and preserving the ocean and coastal ecosystems, and called for “ocean-based action.”
- However, experts say the GST does not capture the necessary urgency to curtail fossil fuel emissions and may encourage the launch of controversial and still-untested geoengineering techniques that aim to lock away carbon in the ocean.
- COP28 was also the stage for several large pledges to support the protection of marine and coastal ecosystems.
Philippines oil spill may reverberate long after cleanup declared complete
- On March 1, the MT Princess Empress oil tanker sank in the Philippines, carrying 900,000 liters (237,754 gallons) of industrial fuel oil. A huge oil slick polluted local waters and prompted authorities to impose a ban on fishing that sent local communities into a tailspin.
- The wreck occurred in the Verde Island Passage, between the Philippines’ main islands of Luzon and Mindoro, an area with the highest concentration of marine biodiversity in the world.
- The spill cleanup activities are now finished, and life is returning to normal in many places. However, experts say the effects of the oil spill on the ecosystem could linger over the long term.
- The spill has reinvigorated calls for the Philippine Legislature to pass a law declaring the entire Verde Island Passage a marine protected area.
Jamaica battles relentless plastic pollution in quest to restore mangroves
- In recent decades, mangroves in Jamaica have declined rapidly, from about 15,000 hectares (37,000 acres) in the 1970s to about 9,945 hectares (24,574 acres) now.
- Currently there are several efforts to restore mangroves in the island country, as experts recognize the many ecosystem services they provide, including the protection and stabilization of coastlines as human-induced climate change worsens.
- However, restoration efforts face numerous challenges: Near Kingston, the main one is voluminous tides of plastic waste, which can stunt mangrove growth or kill them.
Indonesia launches new front in climate campaign focusing on seagrass
- Indonesia has published a road map for seagrass protection and rehabilitation, as part of its efforts to mitigate the impacts of the climate crisis.
- Seagrass meadows are estimated to sequester carbon dioxide from the atmosphere at a much greater rate, hectare for hectare, than even tropical rainforests.
- Indonesia has long been recognized as a crucial country for protecting the underwater flowering plants, as it’s estimated to host at least a tenth of the world’s seagrass meadows.
Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.
Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.
‘Very good progress’ but nothing firm as deep-sea mining rules are hashed out
- Between Oct. 30 and Nov. 8, representatives of the 36 member states of the the International Seabed Authority (ISA) council met in Kingston, Jamaica, to work on a set of regulations that would govern how deep-sea mining activities could proceed.
- Previously, at the ISA meetings that took place in July 2023, delegates agreed to try to finalize the regulations by July 2025.
- However, observers say they believe the regulations are far from being complete, despite continued work on the text.
- The Metals Company (TMC), a Canadian firm that could be the first in the world to begin deep-sea mining, has indicated that it intends to submit an application for exploitation following the July 2024 meeting; if this application is approved, mining could start in the near future without regulations to govern this activity.
Not MPAs but OECMs: Can a new designation help conserve the ocean?
- To meet the landmark commitment struck last year to protect 30% of the ocean by 2030, the world’s nations will have to designate many new and large marine protected areas. But there’s also a different, less familiar option for meeting that target: “other effective area-based conservation measures,” or OECMs, areas that are not necessarily designed to protect biodiversity — they just happen to do so.
- Countries are now working to identify areas that meet the criteria and register them as OECMs, including in Africa where a recent webinar highlighted the promises and pitfalls of this relatively new conservation designation.
- Conservationists say OECMs could bring many positives, including the development, recognition or financing of de facto conservation areas led by local communities or Indigenous peoples.
- However, they also warn of the dangers of “bluewashing” or creating so-called paper OECMs that fail to deliver real conservation benefits in the rush to meet the 2030 deadline.
Amid record melting, countries fail again to protect Antarctic waters
- The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with protecting marine life and managing fisheries in the Southern Ocean, met from Oct. 16-27 in Hobart, Australia, with 26 member countries and the European Union participating.
- For the seventh year in a row, the CCAMLR declined to establish new marine protected areas (MPAs) around Antarctica, despite having committed to creating “a representative network of MPAs” in 2009.
- Scientists, conservationists and some governments have been pushing for greater protections, concerned that the melting ice in Antarctica has reached alarming levels, jeopardizing some key populations of penguins, krill, whales, seals and other marine animals.
- The stalemate came even as a new threat to wildlife emerged in the region: the discovery last week that a virulent form of avian flu had reached Antarctic bird colonies.
New Caledonia expands strictly protected coverage of its swath of the Pacific
- New Caledonia, an overseas territory of France in the Pacific, recently announced that it would highly protect 10% of its economic exclusive zone (EEZ).
- These new highly protected areas will be off-limits to industrial activities such as fishing, drilling and mining.
- A decade ago, New Caledonia designated its entire EEZ as a marine protected area, the Natural Park of the Coral Sea, but industrial activities were permitted across 97.6% of that area at the time.
With record ocean temps, is the Great Barrier Reef facing catastrophe?
- The inaugural international edition of the famed South by Southwest (SXSW) film festival and conference took place from October 15-22, 2023 in Sydney and Mongabay spoke with some of the most interesting presenters there.
- On this edition of the Mongabay Newscast, multiple guests working in coral reef conservation, kelp reforestation and sustainable agriculture detail their projects and challenges they’re tackling.
- Like the catastrophic Great Barrier Reef bleaching event of 2016, if the current conditions line up just right, “we could lose a huge part of the reef by February,” says guest Dean Miller of the Forever Reef Project, which is now racing to add the final coral specimens to its “biobank.”
- Guests also include John “Charlie” Veron from the Forever Reef Project, Mic Black from Rainstick, and Adriana Vergés from the Kelp Forest Alliance.
South Africa’s penguins heading toward extinction; will no-fishing zones help?
- With just 10,000 breeding pairs left, the endangered African penguin (Spheniscus demersus) could be extinct in the wild by 2035 if the current rate of population decline continues.
- To protect the bird’s food supply and slow its population collapse, South Africa is throwing a protective no-fishing cordon around its main breeding colonies for a period of 10 years.
- But the devil is in the details, and conservationists say the cordons are too small to ensure the penguins get enough fish.
- Negotiations over whether to adjust the cordons are continuing in advance of an early 2024 deadline.
Microplastics pose risk to ocean plankton, climate, other key Earth systems
- Trillions of microplastic particles in the ocean threaten marine life, from huge filter-feeders to tiny plankton. Although not lethal in the short term, the long-term impacts of microplastics on plankton and marine microbes could disrupt key Earth systems such as ocean carbon storage and nitrogen cycling.
- Oceans represent Earth’s largest natural carbon store and are crucial to mitigate atmospheric CO2 increase. Carbon taken up by plankton and stored in the deep ocean — known as the biological carbon pump — is a major process in ocean carbon storage. Microplastics may “clog” this pump and slow ocean carbon uptake.
- Microplastics in marine sediments alter microbial communities and disrupt nitrogen cycling, potentially magnifying human-caused problems like toxic algal blooms. Changes in plankton communities at the ocean surface could exacerbate deoxygenation driven by climate change, starving marine organisms of oxygen.
- Small plastic particles are impossible to remove from the oceans with current technology, so stopping pollution is a priority. Plastic production continues to soar year-on-year, but a U.N. treaty to address plastic pollution could offer a glimmer of hope that the international community is ready to take action.
Study finds old pear trees make for surprisingly rich reef habitats
- In a new study, researchers used old pear trees to create artificial reefs and settled them in the Wadden Sea in the Netherlands to see what kinds of marine biodiversity aggregated on or around them.
- They found that the tree reefs attracted a surprising amount of biodiversity over a short period of time, including sessile organisms like barnacles and mobile species like fish and crabs.
- The authors say tree reefs can be replicated in other parts of the world, mainly temperate regions.
Pacific alliance adopts moratorium on deep-sea mining, halting resurgent PNG project
- The Melanesian Spearhead Group put in place a moratorium on deep-sea mining within its member countries’ territorial water in a declaration signed Aug. 24.
- Leaders from Fiji, Papua New Guinea, the Solomon Islands, Vanuatu and an alliance of pro-independence political parties known as FLNKS from the French territory of New Caledonia said more research is needed to establish whether mining the seabed below 200 meters (660 feet) is possible without damaging ecosystems and fisheries.
- The moratorium ostensibly thwarts the return of Nautilus Minerals, a Canadian company, to Papua New Guinea and its Solwara 1 project in the Bismarck Sea, where it had hoped to mine gold and copper from sulfide deposits on the seafloor.
- Proponents of deep-sea mining say that minerals found deep beneath the ocean are necessary for the production of batteries used in electric vehicles and thus are critical in the global transition away from fossil fuels.
Deep-sea mining project in PNG resurfaces despite community opposition
- An embattled deep-sea mining project appears to be moving ahead in Papua New Guinea, according to officials in the Pacific Island nation, despite more than a decade of opposition from local communities on the grounds that it could harm the fisheries on which they rely as well as the broader ecosystem.
- Backers of deep-sea mining say it could help provide the gold, copper and other minerals necessary for the transition to electric vehicles and away from fossil fuels.
- But deep-sea mining has not yet happened anywhere in the world, and scientists, human rights groups and Indigenous communities highlight the lack of evidence demonstrating its safety.
- The Alliance of Solwara Warriors is a group of Indigenous communities and church organizations that have been fighting the Solwara 1 project in Papua New Guinea, which received the world’s first deep-sea mining license from PNG in 2011.
‘All will be well’: Q&A with Kenyan fisher turned coral gardener Katana Ngala
- Once a fisherman, Katana Ngala has been restoring corals near his home in Kuruwitu, Kenya, for more than 20 years.
- Early on, the area’s coral was degraded due to destructive fishing practices and coral bleaching, and he and other fishermen were experiencing diminished catches.
- Now the coral and fish are flourishing in the area, which the local community set aside as a no-fishing zone.
- Ngala spoke about the changes he’s seen in the coral garden over time and how he shares his commitment to the sea with fishers, students, scientists and the wider community in an interview with Mongabay at his seaside coral workshop.
Kenyan fishers put new twists on an age-old marine conservation system
- Over the past two decades Kenyan fishing communities have been setting up no-fishing zones called tengefus, Swahili for “set aside.”
- The idea was inspired by the fishing habits of their forebears, who prior to colonization established seasonal fishing closures to ensure plentiful harvests.
- Today there are 22 tengefus in various stages of development in the country, some more successful than others.
- Successful tengefus have seen fish populations and coral cover increase, and they’ve established tourism enterprises that fund community initiatives. To work, experts say tengefus need support from communities, donors and the government.
Rio de Janeiro’s defender of mangroves
- Guanabara Bay in Rio de Janeiro has suffered for decades from inefficient sewage treatment, oil spills and mangrove deforestation.
- For more than 30 years, biologist Mario Moscatelli has been fighting to reverse this process and revitalize the landscape.
- For denouncing corruption, environmental crimes and government inaction, he faced intimidation and even death threats.
Prickly babies: A Jamaican nursery aims to restore sea urchins felled by disease
- The long-spined sea urchin (Diadema antillarum) is a key algae grazer in the Caribbean. A disease outbreak in the 1980s killed off most of the urchins, resulting in the overgrowth of many Caribbean coral reefs with algae.
- Last year, a recurrence of the disease hampered the species’ slow recovery. This time, scientists were able to discover the culprit, which they revealed in a recent paper.
- The waters of Jamaica’s Oracabessa Bay Fish Sanctuary remained largely unaffected by the disease. Scientists there collected healthy long-spined sea urchins and started an urchin nursery in hopes of restoring the species on reefs around the island.
- This story was produced with support from the Pulitzer Center.
‘The deep sea is vital to protect the ocean’: Q&A with France’s Hervé Berville
- In November, France took a strong position on deep-sea mining by declaring that this future activity should be banned in international waters. The nation has also banned it from its national waters.
- Berville also said he wants to make sure there is a “coalition in favor of a principle of precaution or moratorium.”
- Member states of the International Seabed Authority, the UN-associated mining regulator, recently agreed to push back its timeline for finalizing rules that would enable deep-sea mining to start.
- Mongabay’s Elizabeth Claire Alberts interviewed Berville at the French Embassy in Kingston, Jamaica, during the meeting of the ISA assembly in July.
Plastic ‘Frankenrocks’ pose new pollution threat to coastal environment
- Scientists are finding more evidence of a new, insidious form of plastic pollution: melted plastic that has melded with rocks, coral and other naturally occurring material in coastal areas.
- Samples of these “Frankenrocks” collected from a single beach on a single island in Indonesia were likely formed by the burning of plastic trash.
- They pose a danger to marine life because they can break down into microplastics that then enter the food chain, and can also leach toxic chemicals into the environment.
- Scientists have called for more study into this new and growing phenomenon, saying these Frankenrocks require specialized cleanup management to ward off a “serious problem.”
The endless struggle to clean up Rio de Janeiro’s highly polluted Guanabara Bay
- Once a nursery for marine life, Guanabara Bay in Rio de Janeiro is now dying from the dumping of thousands of liters of sewage into its waters; artisanal fishers now survive by picking up the garbage that floats in the bay.
- Faced with failed promises of de-pollution by the government, civil society organized itself, creating areas of environmental protection and pressuring the companies responsible for basic sanitation in the state, which is still deficient today.
- On the shores of the Rodrigo de Freitas lagoon, a biologist started replanting the mangroves; life returned and the site has become a model of what can be done to save the Guanabara Bay.
Deep-sea mining meetings conclude after stalemate on key agenda items
- Negotiations by member states of the International Seabed Authority (ISA), a U.N.-associated regulator, broke down at a crucial meeting in Kingston, Jamaica, before delegates reached a partial compromise in the final hours.
- The point of contention was whether to discuss two proposals at the meeting: one to conduct a review of the ISA itself and the other to discuss the possible consequences to the marine environment from a rule on deep-sea mining.
- The previous week, member states of the ISA council, the organization’s policymaking body, agreed to aim for July 2025 to finalize rules, regulations and procedures to govern deep-sea mining.
- Deep-sea mining has not yet begun anywhere in the world, but the potential impacts of this activity have stirred controversy.
Deep-sea mining rules delayed two more years; mining start remains unclear
- Member states of the International Seabed Authority (ISA) are currently meeting in Kingston, Jamaica, to discuss the future of deep-sea mining in international waters.
- These current meetings were highly anticipated because they coincided with the expiration of a rule that could have enabled deep-sea mining to start in the near future.
- On July 21, nations intensely negotiated an agreement to finalize regulations for deep-sea mining by July 2025, although this timeline is not legally binding.
- While companies can now technically apply for mining licenses, experts say the new agreement may make it more difficult for these to be approved before the mining regulations are finalized.
Seaweed farmers in eastern Indonesia struggle in a changing climate
- Seaweed farmers in Indonesia are losing out on revenue from their harvests as a result of erratic weather patterns and warming waters — signs of climate change impacts.
- The warming seas encourage the growth of a bacteria that attacks the commercially valuable Eucheuma cottonii species of seaweed.
- To avoid this, farmers are harvesting their crops earlier, before the seaweed grows to the optimal size, giving them a smaller yield and lower revenue at the market.
- The farmers have devised some workarounds to adapt to the situation, but say these solutions can’t be sustained in the face of a changing climate.
Clean me a river: Southeast Asia chokes on Mekong plastic pollution
- New research shows that the drift of microplastics from the Mekong River to the coastlines of countries around the South China Sea depends on variable factors, including seasonal changes in winds and ocean currents.
- The Philippines is most exposed to plastic waste that mainly drifts from the Mekong River to the sea during the monsoon season, with 47% of the stranded particles ending up on its coast, followed by Indonesia at 24%, Vietnam at 17%, and Malaysia at 8%.
- Environmental advocates say the findings of this study underscore the importance of international cooperation in combating plastic pollution, which harms marine biodiversity and coastal economies.
Science and culture join forces to restore 120 miles of Hawaiian reefs
- A new program in Hawai‘i, known as Ākoʻakoʻa, will focus on restoring 193 kilometers (120 miles) of coral reefs off the west of the Big Island, which have been in
decline for the past 50 years.
- A key aspect of the program will be the building of a new research and coral propagation facility in Kailua-Kona on the Big Island.
- While the program will be largely science-driven, it will also rely on the traditional knowledge of community leaders and cultural practitioners.
Expedition to Pacific ecosystems hopes to learn from their resilience
- An expedition led by National Geographic’s Pristine Seas project will voyage across the Pacific over five years to gather information about marine ecosystems needing protection.
- The Pristine Seas team will collaborate with Pacific island nation governments, communities, Indigenous and local peoples, and local scientists, to gather data and produce films.
- The first stop of the expedition will be the southern Line Islands, part of Kiribati, to understand how its reefs recovered after an El Niño triggered a large-scale bleaching event in 2015 and 2016.
Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.
Indonesia’s new capital ‘won’t sacrifice the environment’: Q&A with Nusantara’s Myrna Asnawati Safitri
- The ongoing development of an entirely new capital city from the ground up in Indonesia has alarmed environmental and Indigenous rights activists, who have warned of both deep ecosystem and social impacts.
- The government has justified the plan to move the nation’s capital from Jakarta, on the island of Java, to Indonesia Borneo as a way of ensuring a greater share of development beyond the country’s western islands.
- Mongabay has already reported on the risks to the wider Bornean region and the additional pressures on marine ecosystems that are a biodiversity haven.
- In response, Myrna Asnawati Safitri, the deputy for environment and natural resources at the government agency overseeing the development, reached out for an exclusive interview where these and other thorny questions were addressed.
Parasites of the Caribbean: Study pinpoints cause of sea urchin die-off
- Once abundant in the Caribbean, long-spined sea urchins (Diadema antillarum) experienced a mass die-off in the early 1980s, contributing to coral reef deterioration.
- Another die-off occurred in 2022, leading to a further decline in coral reef health in some parts of the Caribbean.
- A new study has identified the culprit: a parasite called a ciliate that took over the sea urchins’ bodies and quickly killed them.
- While researchers are still trying to determine how this disease is transmitted, they say it’s possible that climate change played a role.
Norway proposes opening Germany-sized area of its continental shelf to deep-sea mining
- Norway has proposed opening up a Germany-sized part of the Norwegian Sea to deep-sea mining.
- The area holds considerable quantities of minerals needed for renewable energy technologies, such as magnesium, cobalt, copper, nickel and rare-earth metals.
- The Norwegian government and industries say they will take a precautionary approach to this deep-sea mining.
- However, critics say plans should be progressing more slowly to properly assess the marine environment and the possible impacts of mining, and the Norwegian government received numerous responses during a public consultation period arguing that the country should not mine its deep sea.
Bringing the ocean’s vast ‘awesomeness’ to light: Q&A with Farah Obaidullah
- “The Ocean and Us,” edited by ocean advocate Farah Obaidullah, provides information from more than 35 female experts on various topics related to the ocean.
- These cover, among others, climate change, overfishing, pollution, ocean management schemes, the human relationship with the ocean, and inclusion and diversity in the ocean space.
- The book helps fulfill the aims of “ocean literacy,” a concept identified by the United Nations as a key driver for achieving the U.N. Decade of Ocean Science for Sustainable Development outcomes.
- “The Ocean and Us” was published by Springer Nature in February 2023.
To build its ‘green’ capital city, Indonesia runs a road through a biodiverse forest
- A new toll road in Indonesia’s East Kalimantan province is under construction to improve access to the interior of Borneo, including to the nation’s new capital city, Nusantara.
- Construction of the road, however, poses immediate environmental risks, as the route cuts through a forested area with high conservation value that connects the Sungai Wain protected forest, coastal mangroves, and Balikpapan Bay.
- Prior to road construction, the integrated forest and coastal ecosystem supported populations of orangutans, sun bears, proboscis monkeys and Irrawaddy dolphins.
- Conservationists say the construction of this toll road belies the Indonesian government’s claims that the development of the new capital will be green and sustainable.
‘Plasticosis’: the new disease killing seabirds and likely many other species
- Scientists have identified a new fibrotic disease called “plasticosis” in flesh-footed shearwaters, a species that inadvertently consumes plastic.
- They found that plasticosis was even present in shearwaters with only a small quantity of plastic in their stomachs.
- While this plastic-related disease has thus far only been identified in flesh-footed shearwaters, experts say that nearly every organism — including humans — is being impacted by plastic in some way.
As Indonesia’s new capital takes shape, risks to wider Borneo come into focus
- Indonesia’s plan to build its new capital city on an expiring logging concession in eastern Borneo has sparked concerns among environmental and human rights observers about the larger eco-social impacts to the rest of the island.
- The administration of President Joko Widodo, who made the decision and will leave office next year, has made glowing promises of a green and sustainable development: claiming minimal forest clearance, respect for Indigenous and local communities’ rights, and a net-zero carbon emission design.
- Mongabay visited the site of the project last October to see its progress, observe firsthand some of the earliest impacts from the construction of the city and supporting infrastructure, and speak with the people most likely to be affected.
- Clearing of mangroves and high-conservation forest areas, land conflicts with Indigenous communities, and potentially large-scale displacements are already happening, calling into question whether the $34 billion project’s benefits will outweigh its downsides.
Will new bottom trawling rules do enough to protect South Pacific seamounts?
- The South Pacific Regional Fisheries Management Organisation (SPRFMO) is an intergovernmental body that regulates fishing across the vast international waters of the South Pacific Ocean.
- At a meeting in Manta, Ecuador, in February, the SPRFMO changed its rules around bottom trawling, a controversial fishing practice that involves dragging fishing gear along the seabed, running roughshod over any organisms or structures in its path.
- The new rules mandate the protection of at least 70% of species that indicate the presence of so-called vulnerable marine ecosystems, such as sponge fields and cold-water coral communities.
- However, conservationists have decried the new rules, calling them less protective than the current policy, let alone the ban on trawling seamounts they’ve been asking for.
Machine learning makes long-term, expansive reef monitoring possible
- Conservationists can now monitor climate impacts to expansive marine ecosystems over extended periods of time, a task that used to be impossible, using a tool developed by scientists in the U.S.
- The machine learning tool, called Delta Maps, provides a new way to assess which reefs might be best suited for survival, and which play a key role in delivering larvae to others, and therefore should be targeted for preservation efforts, according to the scientists.
- The scientists used the tool to examine the impacts of climate change on connectivity and biodiversity in the Pacific Ocean’s Coral Triangle, the planet’s most diverse and biologically complex marine ecosystem.
- The authors also noted that the Coral Triangle had more opportunities for rebuilding biodiversity, thanks to the region’s dynamic climate component, than anywhere else on the planet.
Experts pushing for high-seas fishing ban win ‘Nobel Prize for environment’
- Fisheries experts Daniel Pauly and Rashid Sumaila have won the 2023 Tyler Prize for Environmental Achievement, an award administered by the University of Southern California.
- The prize has been referred to as the “Nobel Prize for the environment” and comes with a $250,000 award to be shared between the two laureates.
- Both Pauly and Sumaila have said they would like to use the prize opportunity to spread the message that it’s necessary to ban all fishing on the high seas, those parts of the ocean that don’t fall under any national jurisdiction.
On Lombok, rising sea levels force fishers into different jobs
- Residents of the Indonesian island of Lombok say sea levels are rising at alarming levels, swallowing seaside towns.
- People are abandoning their family trade of fishing to instead grow seaweed or leave the island for stable employment.
- The provincial government created a climate adaptation task force to address the compounding problems of climate change, as families send their children to school and hope they choose a life different from fishing.
X-Press Pearl salvage continues as study shows toxic effects of disaster
- Salvage operations of the sunken MV X-Press Pearl freighter off Sri Lanka’s west coast has made some progress with the rear section of the wreck successfully raised off the seabed.
- Meanwhile, a new study highlights how the marine disaster significantly impacted the coastal environment, water quality and, in turn, the ocean’s biodiversity, fisheries, seafood industry and the livelihoods of the fishing communities.
- The study records biotoxins produced by harmful algae from sample locations closer to the sunken freighter, a possible reason for a spate of turtle deaths and other marine animals following the MV X-Press Pearl disaster.
- As the environmental impacts were being published through the new study, the second interim report on the environmental damage due to maritime disaster was submitted to the Attorney General’s Department, the chief legal adviser to the government of Sri Lanka, which is expected to file a compensation claim in Singapore.
An El Niño is forecast for 2023. How much coral will bleach this time?
- Forecasts suggest that an El Niño climate pattern could begin later this year, raising sea temperatures at a time when global temperatures are already higher than ever due to human-driven climate change.
- If an El Niño develops and it becomes a moderate to severe event, it could raise global temperatures by more than 1.5°C (2.7°F) above pre-industrial levels, the threshold set by the Paris Agreement.
- An El Niño would generate many impacts on both terrestrial and marine ecosystems, including the potential for droughts, fires, increased precipitation, coral bleaching, invasions of predatory marine species like crown-of-thorns starfish, disruptions to marine food chains, and kelp forest die-offs.
Mongabay Explains: What’s the difference between artisanal and industrial fishing?
- A new episode of “Mongabay Explains” examines the difference between artisanal and industrial fishing.
- Broadly speaking, artisanal fishing is a form of traditional fishing that uses relatively small, low-powered boats to make short trips close to shore and catch relatively small quantities of fish, whereas industrial fishing uses large vessels that make longer trips farther out to sea and catch larger volumes of fish.
- There are plenty of other differences between the two fishing sectors, too, including their relative impact on the marine environment.
- In this video, Mongabay explores the differences between the two forms of fishing, including some ways people are trying to make each sector more sustainable.
Re-carbonizing the sea: Scientists to start testing a big ocean carbon idea
- Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit temporarily, ocean acidification.
- Some scientists believe OAE could be a vital tool for drawing down and securely storing some of the excess CO₂ humanity has added to the atmosphere that is now fueling climate change.
- Yet many questions about OAE remain, including most prominently how it would impact marine life and ecosystems.
- Several programs are aiming to spark the research needed to answer these questions, including field tests in the ocean.
More than half of reef sharks and rays threatened with extinction, study shows
- More than half of known species of coral reef sharks and rays are already threatened with extinction, mostly because of overfishing, according to new research.
- The researchers reported that population trends were declining for 94 coral reef shark and ray species; of the two groups, rays were more threatened than sharks.
- Reef sharks and rays are typically caught for human consumption, and to a lesser extent for use in apparel or accessories, in aquarium displays, as food for domestic animals, and in traditional medicine.
- The study calls for urgent urgent measures to improve regional fisheries and marine protected areas management.
2022’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2022.
- Hopeful developments this past year include the launch of negotiations on the world’s first legally binding international treaty to curb plastic pollution, a multilateral agreement to ban harmful fisheries subsidies and a massive expansion of global shark protections.
- At the same time, the climate crises in the ocean continued to worsen, with a number of record-breaking marine heat waves and an accelerated thinning of ice sheets that could severely exacerbate sea level rise, underscoring the need for urgent ocean-climate actions.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Hunting for future-proof marine plants in the acidic waters bathing a volcano
- The naturally acidic seawater near an underwater volcano in Italy mimic pH levels that according to worst-case climate projections will be common by the end of the century and beyond.
- Scientists are studying local seagrass and seaweed responses to the acidic conditions.
- One question is whether they could be used for restoration purposes in other places that may become more acidic in a not-so-distant future.
- Even so, some researchers point out that these carbon-sequestering marine plants face more immediate challenges from pollution, habitat degradation and warming waters that need addressing for restoration to succeed.
Mongabay Explains: What’s all the brouhaha over bottom trawling?
- A new episode of “Mongabay Explains” examines the controversial fishing method known as bottom trawling, in which vessels drag a net across the seafloor to scoop up bottom-dwelling marine life.
- Ever since the 14th century, fishers who use other gear types — later joined by conservationists and scientists — have objected to bottom trawling, saying the gear takes too many fish and destroys seafloor habitat that’s essential to the functioning of marine ecosystems.
- Proponents of bottom trawling, however, argue that the practice provides an important share of our seafood as well as numerous jobs, and cannot be abandoned.
- In this video, Mongabay takes a look at bottom trawling and the reasons it’s so controversial.
Plastic pellet pollution can end through coordinated efforts, report shows
- Tiny plastic pellets called nurdles are a major source of global pollution, littering waterways, harming ecosystems and threatening marine life.
- But plastic pellet pollution is preventable, according to a new report by the international conservation group Fauna & Flora International (FFI), and it’s one piece of the global plastic problem that can and should be tackled.
- Solving the problem will require coordinated efforts by companies, governments and the International Maritime Organization (IMO), according to FFI.
Extinct sea cow’s underwater engineering legacy lives on today, study finds
- In a new study, scientists said that the extinct Steller’s sea cow impacted kelp forests in the North Pacific by browsing at the surface, which would have encouraged the growth and strengthening of the algal understory.
- Not only would sea cows have positively impacted kelp forests in the past, but they may have also enhanced their resilience into modern times, according to the authors.
- Globally, kelp forests face many threats, including ocean warming, which can lead to an overabundance of predatory urchins.
- The authors suggest that it might be possible for humans to reproduce the species’ impact on the canopy of kelp forests to enhance kelp forest resilience.
Shark-fishing gear banned across much of Pacific in conservation ‘win’
- The Western and Central Pacific Fisheries Commission has outlawed shark lines and wire leaders, both of which aid industrial-scale fishers in targeting sharks.
- Shark numbers in the open ocean have dropped by roughly 71% in the past 50 years.
- Proponents consider the measure a potentially precedent-setting move that could precede similar bans in other regions.
Will shipping noise nudge Africa’s only penguin toward extinction?
- The African penguin (Spheniscus demersus) is expected to go extinct in the wild in just over a decade, largely due to a lack of sardines, their main food.
- A colony in South Africa’s busy Algoa Bay is suffering a population crash that researchers say coincides with the introduction of ship-to-ship refueling services that have made the bay one of the noisiest in the world.
- They say theirs is the first study showing a correlation between underwater noise pollution and a seabird collapse.
- Current studies are investigating whether the ship noise is interfering with the penguins’ foraging behavior and their ability to find fish.
Breeding success raises hopes for future of endangered African penguin
- Two African penguin chicks have hatched at a nature reserve in South Africa where conservationists have been working for years to entice the endangered birds to breed.
- The colony was abandoned more than 10 years ago after a caracal killed a number of penguins.
- The recent hatching comes at a time when survival prospects for Africa’s only resident penguin species look grim, due mainly to declining food stocks.
- But encouraging new colonies at sites close to abundant food sources could help to bring the species back from the brink.
France’s Macron joins growing chorus calling for deep-sea mining ban
- On Nov. 8, French President Emmanuel Macron became the first head of state to call for a complete ban on deep-sea mining, an activity that would extract industrial quantities of minerals from the seabed in international waters in the near future.
- Delegates of the International Seabed Authority (ISA) are currently meeting in Kingston, Jamaica, to discuss deep-sea mining regulations, and many member states are using this forum to express their concerns about mining going ahead.
- In June 2021, the Pacific island nation of Nauru, which sponsors Nauru Ocean Resources Inc. (NORI), a subsidiary of Canadian firm The Metals Company (TMC), triggered a “two-year rule” that could force the ISA to allow mining to go ahead in two years with whatever regulations are in place.
Negotiations to conserve Antarctic Ocean end in stalemate on many issues
- The 41st annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the intergovernmental body charged with conserving marine life in the Southern Ocean and managing fisheries there, ended Nov. 4 with little progress made on several key issues.
- In 2009 CCAMLR committed to creating a network of marine protected areas to preserve Antarctic ecosystems. It established one that year and another in 2016, but since then China and Russia have repeatedly blocked the creation of additional protected areas, as well as other conservation-related measures.
- The commission also failed to reach the consensus required to enact new regulations for the krill and toothfish fisheries, or to protect a vast nesting area for icefish discovered earlier this year.
- CCAMLR members did agree to designate eight new vulnerable marine ecosystems, areas home to slow-growing organisms such as corals, sponges, brittle stars and feather stars that are now permanently protected from bottom fishing.
Plastic impacts a grossly underestimated ‘one-two punch’ for seabirds: Study
- That plastic pollution is harmful to marine life, including seabirds, is well known, but recent research finds that the impacts may be “grossly underestimated” and that plastics can affect multiple organs.
- A new study investigated plastic ingestion by flesh-footed shearwaters and found that — as was determined in past research — initial consumption can harm the stomach. New evidence also showed that impacts are far more expansive, and may cause ongoing health problems distributed throughout body organs.
- Some forms of tissue damage detected by the new research suggest that plastic particles may also act as chemical pollutants, though this requires further study.
- Plastic pollution is a massive growing problem for the world’s oceans and marine life. Earlier this year, researchers announced that the global planetary boundary for novel entities — including plastics — has been surpassed, threatening Earth’s operating systems and life as we know it.
Proposal to grant the ocean rights calls for a sea change in legal framework
- In 2022, the professional sporting group the Ocean Race launched a bid to establish the Universal Declaration of Ocean Rights (UDOR).
- The proposed legal structure would give the ocean legal rights within a multilateral governance system.
- While some laws protect parts of the ocean, there is currently no framework to specifically recognize the ocean’s inherent rights on a national or international level.
- Various countries have already voiced their support for the UDOR, including Monaco, Cabo Verde and Panama.
A ‘super reef’ recovery raises hopes — but also questions about its resilience
- Experts documented the substantial recovery of coral reefs around the southern Line Islands in the central Pacific after the area was hit by a large-scale coral bleaching event in 2015 and 2016.
- Many factors may have contributed to the reef’s recovery, including the fact that the reef is seemingly untouched by human activity, which helped maintain a healthy and resilient ecosystem.
- But other experts question whether this reef would be able to recover after more frequent bleaching events, which are predicted to increase as global temperatures continue to rise.
Mangroves and wildlife in Bornean bay at risk from Indonesia’s new capital
- Experts and activists say the construction of Indonesia’s new capital city upstream of Balikpapan Bay on the island of Borneo fails to mitigate against damage to the marine ecosystem.
- The stretch of coast between the bay and the mouth of the Mahakam River is packed with mangroves, which host a rich diversity of marine and terrestrial life, including proboscis monkeys and Irrawaddy dolphins.
- The government has said the construction of the new capital, Nusantara, will include retaining a large swath of mangrove forest, but zoning details show most of it won’t be protected against development.
- The $33 billion planned city will in 2024 take over as the Indonesian capital from Jakarta, and its full construction will be completed by 2045, according to the government’s plans.
Indonesian program pays fishers to collect plastic trash at sea
- The Indonesian fisheries ministry has launched a four-week program to pay fishers to collect plastic trash from the sea.
- The initiative is part of wider efforts to reduce Indonesia’s marine plastic pollution by 70% by 2025.
- The country is a top contributor to the plastic trash crisis in the ocean.
- Each of the 1,721 participating fishers will receive the equivalent of $10 a week for collecting up to 4 kg (9 lbs) of plastic waste from the sea daily.
‘Destructive & flawed’: Claire Nouvian on bottom trawling’s many impacts
- Goldman Environmental Prize winner Claire Nouvian joins the Mongabay Newscast to discuss the many impacts of bottom trawling and a historic policy shift by the European Commission to rein in the practice.
- This kind of fishing is known for damaging deep-water coral reef ecosystems and marine biodiversity, and for having a heavy carbon footprint.
- Nouvian discusses the successful activism of her organization that won an EU-wide ban on bottom trawling below 800 meters (875 yards) after seven years of grassroots organizing. She also discusses what individuals can do if they want to support more sustainable fishing practices.
‘One more thing’ about plastics: They could be acidifying the ocean, study says
- New research suggests that plastic could contribute to ocean acidification, especially in highly polluted coastal areas, through the release of organic chemical compounds and carbon dioxide, both of which can lower the pH of seawater.
- The study found that sunlight enabled this process and that older, degraded plastics released a higher amount of dissolved organic carbon and did more to lower the pH of seawater.
- However, the findings of this study were conducted in a laboratory, so it’s unclear whether experiments conducted in estuaries or the open ocean would yield similar results, experts said.
Regulator approves first deep-sea mining test, surprising observers
- The International Seabed Authority (ISA), the intergovernmental body responsible for overseeing deep-sea mining operations and for protecting the ocean, recently granted approval for a mining trial to commence in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.
- The company undertaking this trial is Nauru Ocean Resources Inc (NORI), a subsidiary of Canadian-owned The Metals Company (TMC), which is aiming to start annually extracting 1.3 million metric tons of polymetallic nodules from the CCZ as early as 2024.
- The approval for this mining test, the first of its kind since the 1970s, was first announced by TMC earlier this week.
- Mining opponents said the ruling took them by surprise and they feared it would pave the way for exploitation to begin in the near future, despite growing concerns about the safety and necessity of deep-sea mining.
Sri Lanka eyes major compensation case over X-Press Pearl sinking
- Sri Lanka has received $2.5 million in the third interim payment for the sinking of the X-Press Pearl cargo ship in June 2021, giving it a total of just $7.85 million for the worst maritime disaster in the country’s history.
- These payments from the Singapore-flagged vessel’s insurer are mainly to reimburse the government for the cost of the emergency response operations and for direct damages and cleanup.
- Environmental lawyers say the government can and should pursue a much larger compensation claim for the environmental damage wrought.
- The X-Press Pearl sank off Sri Lanka’s western coast after catching fire, in the process spilling its cargo of hazardous chemicals and billions of plastic pellets that continue to dot the country’s beaches.
Acid test: Are the world’s oceans becoming too ‘acidic’ to support life?
- The world’s oceans absorb about a quarter of humanity’s carbon dioxide emissions, buffering us against higher atmospheric CO2 levels and greater climate change. But that absorption has led to a lowering of seawater pH and the acidification of the oceans.
- The process of ocean acidification is recognized as a leading threat to ocean life due to its impairment of calcifying organisms and other marine species. The full impacts of acidification are unknown, but at some point reduced pH could be disastrous biologically.
- Researchers have designated ocean acidification as one of nine planetary boundaries whose limits, if transgressed, could threaten civilization and life as we know it. But there is debate as to whether there is a global boundary for this process, since acidification impacts some regions and species more or less than others, making it hard to quantify.
- Scientists agree that the primary solution to ocean acidification is the lowering of carbon emissions, though some researchers are investigating other solutions, such as depositing alkaline rock minerals into oceans to lower the pH of seawater.
‘Mind-blowing’ marine heat waves put Mediterranean ecosystems at grave risk
- A recent study reveals the widespread effects of climate change-driven marine heat waves on the ecological communities of the Mediterranean Sea.
- Rises in sea surface temperatures as high as 5° Celsius (9° Fahrenheit) above normal have caused die-offs in 50 different taxonomic groups of animals from around the Mediterranean Basin.
- These far-reaching impacts of the warming sea could devastate the fisheries on which many of the Mediterranean region’s 400 million people rely.
- Researchers advocate bolstering and expanding marine protected areas. Although they can’t hold back the warmer waters that have proven deadly to the sea’s rich biodiversity, these sanctuaries can help ensure that these species don’t have to cope simultaneously with other pressures, such as overfishing or pollution.
Delegates come close, but fail again to clinch high seas protection treaty
- At the close of two weeks of negotiations on Aug. 26 in New York, delegates from around the world had failed to net consensus on a high-stakes, legally binding treaty to conserve biodiversity on the high seas.
- These areas beyond national jurisdictions comprise two-thirds of the global ocean and are a vast, resource-rich global commons. Yet there is no comprehensive, agreed-upon framework governing resource extraction or conservation there.
- Top sticking points included fair access to marine resources for all and how to establish marine protected areas on the high seas.
- The meeting was the fifth of four planned diplomatic sessions that began in 2017 following more than 10 years of discussion. It ended with a commitment to reconvene before the year is over.
Three-fourths of waste in Jakarta’s notoriously polluted rivers is plastic
- Most of the waste collected from the rivers and holding facilities in Indonesia’s capital, Jakarta, is plastic, new field-based research has found.
- Researchers note that the plastic debris recovered from the surface water amounted to 9.9 grams, or a third of an ounce, per person on average, which is lower than an estimate from a widely cited 2015 study.
- The researchers have called for a better mitigation strategy to eliminate plastic pollution in rivers and subsequently the ocean.
- Indonesia, a country of more than 270 million people, is the No. 2 contributor to global marine plastic pollution, behind only China.
Study paints ‘bleak picture’ for nearly all marine life without emissions cuts
- New research published in Nature Climate Change has found that nearly 90% of assessed marine life would be at high or critical risk by 2100 if the world continues upon a high-emissions pathway.
- It found that the risks would be more concentrated in the tropics, and that top predators would be more at risk than species lower down the food chain.
- However, if countries drastically reduce their emissions, the study found that climate risk would decrease for more than 98% of these species.
Overlooked and at risk, seagrass is habitat of choice for many small-scale fishers
- Seagrass meadows, rather than coral reefs, are the fishing grounds of choice for many fishing households in four countries in the Indo-Pacific region, a new study shows.
- Fishers in Cambodia, Tanzania, Indonesia and Sri Lanka identified seagrass meadows as being more easily accessible than coral reefs, often without the need for a boat, and less likely to damage equipment such as nets.
- However, seagrasses around the world are disappearing at rates that rival those of coral reefs and tropical rainforests, losing as much as 7% of their area each year.
- The study makes the case for better-informed management of these marine habitats, to ensure their sustainability for the marine life and people who depend on them.
Amid haggling over deep-sea mining rules, chorus of skepticism grows louder
- This week, the International Seabed Authority, the intergovernmental body tasked with overseeing deep-sea mining in international waters, concluded its recent set of meetings, which ran from July 4 to Aug. 4, 2022.
- The purpose of these meetings was to progress with negotiations of mining regulations, with a view that deep-sea mining will start in July 2023 after the Pacific island nation of Nauru triggered a rule that could obligate this to happen.
- While many countries appear to support the rapid development of these regulations, an increasing number of other countries have expressed concern with this deadline, indicating a possible turn of events.
Sea life may downsize with ocean warming — bringing challenging impacts
- A new model predicts that marine microbes could shrink by up to 30% in the future due to climate change, impacting bigger organisms that eat them including fish, potentially disrupting the food chain from the bottom up. Smaller fish would mean impacted fisheries. Smaller microbes could mean less carbon sequestration.
- Warmer oceans hold less oxygen, and the model predicts that sea life will get smaller in response to more limited oxygen. But scientists have long debated why this downsizing occurs, and some say that other factors not considered in the model could impact oceanic microbes in unexpected ways.
- Accurately predicting warming impacts on marine life could improve ocean resource management.
‘We’ve got to help the oceans to help us’: Q&A with deep-sea explorer Dawn Wright
- On July 12, oceanographer and geographer Dawn Wright descended 10,919 meters (35,823 feet) below the surface of the ocean to the deepest known part of the planet, Challenger Deep, alongside deep-sea explorer Victor Vescovo.
- Wright was the first Black person to make the voyage to Challenger Deep, where she and Vescovo documented several findings, including the discovery of a beer bottle on the seabed.
- The goal of the expedition was to test out a side-scan sonar designed to go down to 11,000 m (nearly 36,100 ft) that can take detailed images of the seafloor, which was successfully achieved.
- Mongabay’s Elizabeth Claire Alberts spoke to Wright before and after her expedition to learn more about the voyage’s personal significance to Wright, the challenges in venturing this far down into the ocean, and the significance of understanding more about the deep-sea.
Concerns over transparency and access abound at deep-sea mining negotiations
- Delegates to the International Seabed Authority (ISA), the U.N.-mandated body responsible for overseeing the development of deep-sea mining in international waters and protecting the ocean, are currently meeting in Kingston, Jamaica, to negotiate a set of regulations that would determine how deep-sea mining can proceed.
- Scientists and conservationists say there are many transparency issues at the current meetings, and that the ISA has restricted access to key information and hampered interactions between member states and civil society.
- However, the ISA has stated that it’s committed to transparency and that attendees have full access to the discussions.
- Deep-sea mining could begin in as little as a year with whatever regulations are currently in place.
‘The sea means everything’: Q&A with deep-sea mining opponent Debbie Ngarewa-Packer
- New Zealand parliamentarian and Māori activist Debbie Ngarewa-Packer has spent more than two decades serving in leadership roles, using her positions to advance social justice issues and to campaign for the protection of the marine environment.
- A key issue that Ngarewa-Packer is currently working on is a push to ban deep-sea mining in the global ocean, a proposed activity that would extract large amounts of minerals from the seabed.
- Ngarewa-Packer previously worked with other Māori activists, NGOs and community members to block consent for a deep-sea mining operation in her home district of South Taranaki on New Zealand’s North Island.
- In an interview with Mongabay, Ngarewa-Packer talks about why it’s critical to protect the deep sea from mining, what ancestral teachings say about protecting the ocean, and why she feels hopeful about the future.
Study: Climate impacts to disproportionately hurt tropical fishers, farmers
- The majority of 72 coastal communities studied in five countries in the Indo-Pacific region may face significant losses of agricultural and fisheries products — two key food sources — simultaneously under the worst-case climate change projections, a new study shows.
- These potential losses may be coupled with other drivers of change, such as overfishing or soil erosion, which have already caused declining productivity, the study adds.
- But if carbon emissions can be effectively managed to a minimum, the study’s authors say, fewer communities would experience losses in both the agriculture and fisheries sectors, indicating the importance of climate mitigation measures.
- The current global average temperature is 1.1°C (2°F) above pre-industrial times, and climate experts have warned that it could climb to about 3°C (5.4°F) higher by the end of this century if nothing changes.
Scientists strive to restore world’s embattled kelp forests
- Kelp forests grow along more than one-quarter of the world’s coastlines, and are among the planet’s most biodiverse ecosystems. But these critical habitats are disappearing due to warming oceans and other human impacts.
- Sudden recent wipeouts of vast kelp forests along the coastlines of Tasmania and California highlighted how little was known about protecting or restoring these vital marine ecosystems.
- Scientists are finding new ways to help restore kelp, but promising small-scale successes need to be ramped up significantly to replace massive kelp losses in some regions.
- Global interest in studying seaweed for food, carbon storage and other uses, may help improve wild kelp restoration methods.
U.N. Ocean Conference ends with promises. Is a sea change coming?
- The second United Nations Oceans Conference took place from June 27 to July 1 in Lisbon, focusing on the protection of life under water, as dictated by U.N. Sustainable Development Goal No. 14.
- The conference was originally meant to have taken place in 2020, but was delayed due to the COVID-19 pandemic.
- While nations, NGOs and other entities made hundreds of conservation commitments, including pledges to expand marine protected areas, end destructive fishing practices, and fund conservation efforts, experts say there is still a lot of work to be done to protect our oceans.
- Coalitions of small-scale fishers and Indigenous peoples also voiced their concerns about being excluded from important conservation dialogues.
A year before deep-sea mining could begin, calls for a moratorium build
- At the U.N. Ocean Conference taking place this week in Lisbon, momentum has been building in support of a moratorium on deep-sea mining, an activity projected to have far-reaching consequences for marine ecosystems, biodiversity, and global fisheries.
- The Pacific island nation of Palau launched an alliance of countries that support a moratorium, which Fiji and Samoa subsequently joined.
- A global network of parliamentarians has also banded together to support a moratorium and to look for a legal way to enforce it.
- As things stand, deep-sea mining could begin a year from now, with the International Seabed Authority, the body tasked with regulating the activity, drawing up the rules that would allow mining to commence.
Sea restoration projects quilt a ‘mosaic of habitats’ with striking results
- The concept of restoring more than one type of marine habitat at a time — such as oyster reefs, seagrass meadows and salt marshes — is becoming increasingly popular as scientists and conservationists learn about the advantages of this approach.
- Many studies clearly show the mutual benefits that integrated habitats provide to each other, as well as the larger benefits offered to the ecosystem.
- Yet other studies show mixed results, drawing attention to the complex nature of this approach.
- Numerous seascape restoration projects are taking place around the world, including in the coastal bays of Virginia, U.S., the sea off the coast of South Australia, and the estuaries and lochs in the U.K.
Even Antarctic snow can’t escape the plastic peril, study shows
- A study presents new evidence that microplastics are present in snow in Antarctica, one of the remotest places on Earth.
- Researchers collected snow samples at 19 sites across the Ross Ice Shelf in Antarctica, and found 29 microplastic particles per liter of melted snow — a higher amount than what was found in marine samples in Antarctica.
- The microplastics found in samples close to research stations were three times higher than what was found at other locations, prompting researchers to conclude that much of the plastic was coming from local clothing and equipment.
Ray care center: Indonesia’s Raja Ampat a key nursery for young reef mantas
- Scientists have published new evidence confirming that Wayag Lagoon in Indonesia’s Raja Ampat archipelago is a globally rare nursery for juvenile reef manta rays (Mobula alfredi).
- Visual observations from 2013 to 2021 show that juvenile reef manta rays are repeatedly encountered in the small, shallow and sheltered lagoon, without the presence of adult individuals; the young rays spend months at a time inside the lagoon, never venturing out.
- The findings have prompted marine authorities in Indonesia to start revising the management of the lagoon to safeguard the manta nursery zone, with regulations being drawn up to limit disturbances to the young rays.
- Both oceanic and reef manta rays are protected species under Indonesian law, which prohibits their catch and the trade of any of their body parts.
Indonesia should take a leadership role in the Global Plastics Treaty (commentary)
- Indonesia is one of the world’s biggest producers of plastic and a top source of plastic waste in the ocean.
- The passage by the U.N. of a draft resolution toward a Global Plastics Treaty provides a key opportunity for Indonesia to take a leading role in ushering in a transition to a world without plastics, the authors argue.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
‘Tendrils of hope’ for the ocean: Q&A with conservationist Charles Clover
- The latest book by Charles Clover, “Rewilding the Sea,” published by Penguin Random House UK, tells stories of what can happen when governments, scientists, conservationists and fishers work together to protect and restore the ocean, generating hope for the future.
- While the term “rewilding” usually refers to restoration efforts that take place on land, Clover argues that the sea can also be rewilded through the reinstatement of ecosystems as well as by simply allowing nature to repair itself.
- He further argues that rewilding can be achieved through new approaches to fisheries management, the creation of marine protected areas, and the protection of parts of the ocean known to sequester carbon.
- While the book acknowledges that the oceans are facing a tremendous number of pressures due to human activities, Clover calls the destruction of ocean life the “world’s largest solvable problem.”
A year since X-Press Pearl sinking, Sri Lanka is still waiting for compensation
- The sinking a year ago of the cargo vessel the X-Press Pearl was responsible for the single worst incident of plastic marine pollution in the world, according to a committee assessing the damages from the disaster.
- The ship caught fire off Colombo and eventually sank, leaking its cargo that contained 25 metric tons of nitric acid and some 50 billion plastic pellets.
- A year later, pellets are still washing up on shore and being cleared away by volunteers, while Sri Lanka tries to claim damages from the ship’s Singapore-based operators.
- It has received $3.7 million as initial compensation, but experts say the full compensation for the environmental damage could be as high as $7 billion — a figure that would be a lifeline for Sri Lanka as it experiences the worst economic crisis in its history.
How will climate change impact cold-water corals? Mostly through food loss, study says
- A new study warns that cold-water corals, also known as deep-water corals, could be most impacted by a decrease in food supply as climate change shifts the dynamics of the planet’s oceans.
- The authors came to this conclusion by examining how cold-water corals survived the last major period of global warming that occurred at the end of the last glacial period and the start of the current interglacial period, which is somewhat analogous to how the Earth is projected to warm by the end of this century.
- However, experts point out that cold-water corals today are subjected to a number of additional stressors, including ocean acidification, destructive fishing practices, and pollution, and that the climate is changing far more rapidly than it did in the past.
- Cold-water corals are considered to be equally important — or perhaps even more important — than tropical corals, which makes understanding their chances of survival of the utmost importance, researchers say.
For reef mantas, Indonesia’s Komodo National Park is a ray of hope
- A new study has found that Komodo National Park in Indonesia has an aggregation of 1,085 reef manta rays, currently classified as a vulnerable species.
- Experts say that locations such as Komodo will play an important role in safeguarding the species from extinction.
- Manta rays are under pressure from fishing activity, including targeted fishing and bycatch.
- However, experts say the species is also impacted by tourism and the changing dynamics of the ocean.
To stop plastic pollution, we must stop plastic production, scientists say
- A team of scientists working in the field of plastics has published a letter in Science, calling for the cessation of new plastic production in order to solve the plastic pollution issue.
- Plastic is not only an issue when it comes to its disposal, but its production generates large volumes of greenhouse gas emissions, contributing to the climate crisis, they argue.
- Earlier this year, countries agreed to adopt a global treaty to stop plastic pollution, but the details for this agreement have yet to be determined.
- Negotiators will begin working on a draft of the agreement next month.
‘A huge mistake’: Concerns rise as deep-sea mining negotiations progress
- The International Seabed Authority (ISA), the U.N.-affiliated organization tasked with managing deep-sea mining activities, recently held a series of meetings to continue negotiating the development of mining regulations.
- Deep-sea mining may start as early as 2023 after Nauru triggered a two-year rule embedded in the U.N. Convention on the Law of the Sea that could essentially allow its sponsored company to start mining with whatever regulations are currently in place.
- Many states are eager to finalize a set of regulations over the next 15 months that would determine how mining can proceed in the deep sea.
- But other states and delegates have noted the lack of scientific knowledge around deep-sea mining, the absence of a financial compensation plan in the event of environmental damage, and ongoing transparency issues in the ISA — and the unlikelihood of finalizing regulatory measures in a short period of time.
Stranded coal barge spills cargo, disrupts fishery in Indonesian waters
- An Indonesian coal barge that ran aground off East Java has reportedly spilled much of its cargo and disrupted the local fishery.
- Local fishers blame the spill for turning the water in the area dark and affecting their fishing activities.
- An environmental group has called for an investigation by fisheries and environmental agencies into the incident.
- Indonesia is one of the world’s biggest producers of coal, but has paid a heavy price for that standing, including the massive deforestation wrought to mine the fossil fuel, as well as the numerous environmental and safety incidents associated with transporting and burning it.
NGOs block gillnet fishing across 100,000 sq km of Great Barrier Reef
- In an effort to protect dugongs and other threatened species, WWF-Australia bought a commercial gillnet fishing license for a swath of ocean in the northern Great Barrier Reef, to establish a de-facto marine sanctuary spanning more than 100,000 km2 (38,600 mi2).
- Dugongs, turtles, dolphins and other marine animals are easily caught in gillnets, and experts say many fatalities go unreported.
- The newly protected region is an important feeding ground for dugongs, supporting a local population of about 7,000, experts say.
- WWF-Australia says it hopes the Australian and Queensland state governments will establish more permanent protections for dugongs on the Great Barrier Reef, and that Traditional Owners can use the area for sustainable fishing and tourism.
Oil spill contaminates wildlife, beaches and protected areas in Peru
- On Jan. 15, a refinery owned by Spanish oil company Repsol spilled nearly 12,000 barrels of oil into the sea off Lima, Peru, as it was pumping the oil from a tanker.
- Experts have questioned why the refinery of La Pampilla was operating that day, when there were unusually high waves caused by the Tonga volcano eruption and tsunami.
- Peru’s Environmental Evaluation and Enforcement Agency (OEFA) has fined Repsol for similar spills on at least three prior occasions, and this time the company could be hit with more than $37 million in fines.
- The spill has spread beyond the Lima coast and out toward islands that are part of a network of protected nature reserves, posing serious threats to marine life and to artisanal fishermen.
The Great Barrier Reef is bleaching — once again — and over a larger area
- The Great Barrier Reef is currently experiencing its sixth mass bleaching event, and the fourth event of this kind to happen in the past six years.
- Based on aerial surveys that were concluded this week, bleaching has affected all parts of the Great Barrier Reef, with the most severe bleaching occurring between Cooktown, Queensland, and the Whitsunday Islands.
- Sea surface temperatures around the Great Barrier Reef have been higher than normal, despite the region going through a La Niña climate pattern, which usually brings cooler, stormier weather.
- Climate change remains the biggest threat to the Great Barrier Reef and other reefs around the world, experts say.
Study links many reported fisheries crimes to just a few repeat offenders
- A new study in the journal Science Advances analyzed roughly 8,000 fisheries offenses reported globally between 2000 and 2020, a database the authors call the “largest existing repository” of reported fisheries offenses.
- The study shows that a small number of companies may be responsible for a large chunk of international industrial fisheries crimes.
- It also shows that the vessels committing abuses, such as unauthorized fishing and human rights and labor violations, often engaged in more than one offense.
- Illegal fishing accounts for one fourth the value of all landed seafood products, roughly $30 billion globally. It contributes to the depletion of fish and other marine wildlife populations.
Marine cold spells, a potential buffer against warming seas, are fading away
- A new study has found that marine cold spells have decreased in number and intensity since the 1980s due to climate change.
- Marine cold spells can have both negative and positive impacts on the environment; they can wreak havoc on ecosystems like coral reefs, but they can also buffer the impacts of heat stress during marine heat waves.
- While marine cold spells are decreasing, marine heat waves are increasing — but the relationship between these two kinds of events still isn’t clear, the study says.
Ships sunk in nuclear tests host diverse corals, study says. But do we need them?
- Researchers surveyed 29 warships at Bikini Atoll and Chuuk Lagoon and found that they hosted up to a third of coral genera found on natural reefs in neighboring regions.
- This study has led researchers to ask a controversial question: Can these kinds of shipwrecks act as biodiversity havens for corals?
- While the study does not provide an answer to this question, the authors say this idea should be explored.
- Climate change is one of the biggest threats to coral reefs since rising temperatures can cause widespread bleaching events.
Fourth round of U.N. talks fail to finalize a treaty to manage the high seas
- U.N. member states met this month in New York to hash out a treaty governing the sustainable management of the high seas, resource-rich international waters that span about two-thirds of the ocean.
- Hopes were high that after 10 years of discussion and three previous negotiating sessions, delegates to the meeting would finalize a legally binding treaty.
- Talks ended March 18 with no deal, amid a failure to reach consensus on several key points, including how to establish marine protected areas on the high seas.
- A movement to protect 30% of the ocean by 2030 depends on the swift completion of a high seas treaty, and observers say a deal remains within reach by the end of the year.
Vulnerable Antarctic reefs reveal wealth of life as rich as tropical corals
- A research expedition led by Greenpeace identified about a dozen new vulnerable marine ecosystems in Antarctica’s Weddell Sea, and documented a range of organisms, some of which were previously unknown to science.
- Researchers argue that it’s vital to protect the Weddell Sea since this region helps to regulate the global oceans.
- This week, negotiators are discussing the establishment of a U.N. treaty that would protect the high seas, which could lead to widespread ocean protection.
- In October, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) will also revisit the proposal to establish three marine sanctuaries in Antarctica, including one in the Weddell Sea.
Study finds major brands selling cat food that contain protected sharks
- Researchers used DNA barcoding to find that cat food sold in Singapore from at least 16 different brands contained threatened species of sharks, including silky sharks (Carcharhinus falciformis) that are protected under CITES Appendix II.
- Leading brands such as Fancy Feast, Whiskas, and Sheba were amongst those found to contain silky sharks and other species.
- None of these cat food products were accurately labeled to show that they contained sharks.
- Global shark populations are in sharp decline, mainly due to destructive fishing practices.
Latest Nigeria oil spill highlights ‘wretched’ state of the industry
- An oil production vessel exploded just off the coast of Nigeria on Feb. 3, killing seven of 10 crew members on board.
- Nigeria’s monitoring of and response to oil industry incidents is poor: three weeks later, the size and impact of the spill is still unknown.
- This is the second major incident reported in the past three months, and highlights potential problems as oil majors sell aging infrastructure to locally owned companies that are ill-equipped to operate them safely.
‘They’re going to get worse and worse’: Marine heat wave persists off Sydney
- In November 2021, an unusual marine heat wave materialized off the coast of Sydney; sea surface temperatures in the area have yet to go down.
- This marine heat wave is just one of numerous events occurring across the global oceans as human-induced climate change heats up the oceans.
- While marine heat waves can be triggered by a range of atmospheric, oceanic and climatic drivers, climate change plays a key role in driving these events.
Red seas and no fish: Nickel mining takes its toll on Indonesia’s spice islands
- Fishermen in Indonesia’s Obi Islands blame the nickel mining and smelting industries for the depletion of fish in their traditional fishing grounds.
- Researchers say the pollution has turned the coastal waters into a “mud puddle” because of the high levels of heavy metal contamination.
- One of the main mining companies there had previously proposed dumping 6 million tons of waste a year into the sea, but backed down following protests.
- The company is now proposing clearing a forest area to build a tailings dam — a plan that activists and fishermen say is no better because of the persistently high risk of environmental contamination.
Scientists’ secret weapon to monitor the Southern Ocean? Elephant seals
- Southern elephant seals living on Kerguelen Island, a sub-Antarctic island, are helping to gather information about the Southern Ocean with data-logging devices attached to their hair.
- For instance, the elephant seals have helped gather data on sea ice formation, ocean and ice shelf interactions, and frontal system dynamics.
- The Southern Ocean provides many ecosystem services for the planet, but the region is rapidly changing due to climate change.
Safe havens for coral reefs will disappear as oceans warm, study says
- A new study found that coral reef “refugia” — places that have historically protected coral reefs from thermal stress — will decline substantially when global heating reaches 1.5°C (2.7°F) above pre-industrial levels; at 2°C (3.6°F), most coral reef refugia will disappear.
- A loss in refugia will expose corals to thermal stress that they will likely be unable to cope with, most likely leading to large-scale loss of coral reefs that will threaten marine biodiversity and food security.
- The authors suggest that management efforts should be refocused to help coral reefs adapt to a warming ocean and to assist in their migration to more hospitable locations.
- However, efforts to help corals adapt to rising temperatures may be futile as long as carbon emissions continue to rise.
South Africa authorizes dumping at sea of cargo that turned volatile
- South Africa plans to dump unstable chemicals at sea after they reacted with rainwater during offloading from the NS Qingdao bulk carrier in Durban in October and started releasing toxic fumes.
- The country’s maritime safety authority has until March to dump the cargo of fertilizers and industrial reagents into the open ocean 250 kilometers (155 miles) offshore of the fishing town of St. Helena Bay, a two-hour drive north of Cape Town.
- The emergency authorization for the operation is predicated on it being the most “environmentally, socially and economically” suitable option, but scientists say the dump site overlaps with an area of critical biodiversity within the Benguela Current ecosystem.
- South African authorities said they will investigate what triggered the incident aboard the NS Qingdao, which flies the Marshall Islands flag but has registered owners in Hong Kong.
As climate change melts Antarctic ice, gentoo penguins venture further south
- Researchers have discovered a new colony of gentoo penguins in Antarctica previously unknown to science.
- The colony was found on Andersson Island on the east side of the Antarctic Peninsula, which is the furthest south the species has ever been found in that region.
- Scientists say climate change played a key role in the penguins’ presence on the island, as warming temperatures and record ice melt make new locations habitable for the species.
- Scientists and conservationists are making renewed calls to establish a network for marine protected areas in Antarctica to help safeguard the region as the climate rapidly changes.
Bleached reefs still support nutritious fish, study finds
- A recent study published in the journal One Earth looked at the nutrients available in fisheries in Seychelles before and after bleaching killed around 90% of the island nation’s coral in 1998.
- Warming ocean temperatures have caused mass bleaching of corals across the tropics, sometimes causing the deaths of these reef-building animals, and the phenomenon is expected to continue as a result of climate change.
- The research found that bleached reefs continue to support fisheries that provide essential micronutrients to human communities.
In hot water: Ocean warming hits another record high on climate change
- A new study has found that, for the sixth year in a row, the world’s oceans have been hotter than they’ve ever been in recent history due to human-induced climate change.
- The research team found that last year, the upper 2,000 meters (6,600 feet) in all oceans absorbed 14 zettajoules more of human-made energy than the previous year, equal to about 145 times the world’s electricity generation in 2020.
- A warming ocean creates a multitude of issues, driving extreme weather events, accelerating sea level rise, disrupting marine biodiversity, threatening global food security, and melting polar ice shelves.
- Experts say the best way to reduce ocean climate impacts is to lower carbon emissions and meet the Paris Agreement goal of not allowing global warming to surpass 1.5°C (2.7°F) over preindustrial levels.
New atlas illuminates impact of artificial light in the ocean at night
- Researchers recently released the first global atlas that quantifies artificial light at night on underwater habitats.
- Artificial light from urban environments along the coast can have far-reaching impacts on a range of marine organisms that have evolved over millions of years to be extremely sensitive to natural light such as moonlight.
- The researchers found that at a depth of 1 meter (3 feet), 1.9 million square kilometers (734,000 square miles) of the world’s coastal oceans were exposed to artificial light at night, equivalent to about 3% of the world’s exclusive economic zones.
- Blue tones from LED lights can penetrate particularly deeply into the water column, potentially causing more issues to underwater inhabitants.
Warmer, oxygen-poor waters threaten world’s ‘most heavily exploited’ fish
- A new report using core samples taken from the seabed has determined that the Humboldt Current system off the coast of Peru was home to smaller fish during the last interglacial period, 130,000 years ago.
- The conditions back then — with little oxygen content in the ocean and temperatures about 2°C (3.6°F) warmer than the average temperature in the current Holocene epoch — mirror those that scientists have predicted for 2100.
- While many studies have argued that warmer water and lower oxygen lead to smaller fish, the added pressure of industrial fishing has made it difficult to determine the threat that climate change will pose on fisheries.
- The Humboldt Current system is one of the most productive fisheries in the world, contributing to more than 15% of the global annual fish catch, so significant changes to this system will threaten food security.
‘Great Blue Wall’ aims to ward off looming threats to western Indian Ocean
- Ten nations in the western Indian Ocean committed this November to create a network of marine conservation areas to hasten progress toward the goal of protecting 30% of the oceans by 2030.
- Less than 10% of the marine expanse in this region currently enjoys protection, and a recent assessment highlighted the price of failure: all the coral reefs are at high risk of collapse in the next 50 years.
- The focus of these efforts won’t just be coral reefs, but also mangroves and seagrass meadows, a lesser-known underwater ecosystem critical for carbon sequestration and oceanic biodiversity.
- Even as overfishing and warming take a toll on marine health, threats from oil and gas extraction are intensifying in this corner of the Indian Ocean.
Burnt pellets complicate impact of plastic spill off Sri Lanka, study finds
- Volunteers cleaning up after the sinking of the X-Press Pearl in Sri Lanka say they’ve encountered a lot of burnt nurdles, the basic building block of plastic products, during the initial stages of the cleanup operation.
- A newly published paper highlights how burnt nurdles complicate the environmental challenges — making cleanup operations harder and much more complex, besides proving highly detrimental to marine life.
- The Sri Lankan government has called on the international community to enact new regulations in shipping transportation, landing and loading in order to reduce the risk of accidents like the X-Press Pearl disaster.
Top 15 species discoveries from 2021 (Photos)
- Science has only just begun to find and describe all of the species on Earth; by some estimates, only 20% have been described.
- This year, Mongabay reported on newly described species from nearly every continent, including an Ecuadoran ant whose name broke the gender binary, an acrobatic North American skunk, an Australian “killer tobacco,” a fuzzy orange bat from West Africa, tiny screech owls from Brazil, and more.
- Though a species may be new to science, that doesn’t mean it has not yet been found and given a name by local and Indigenous communities.
Deep-sea mining regulator’s latest meeting on rules only muddies the water
- Delegates of the International Seabed Authority (ISA), the multilateral body in charge of deep-sea mining in international waters, met recently in Kingston, Jamaica, and discussed whether to adopt a set of rules — or mining code — to allow deep-sea mining to commence in as little as 18 months.
- Deep-sea mining is a controversial activity that was pushed closer to the horizon when Nauru triggered a “two-year rule” that would theoretically require the ISA to grant an exploitation license within two years, no matter what mining regulations are in place.
- Most ISA member states appeared to be in favor of pushing forward with the mining code, but others questioned the feasibility of this approach, according to observers who attended the meetings.
- The ISA has a dual mandate to give nations equal opportunity and access to mine the seabed as well as to protect the ocean from mining’s harmful effects, but some experts say the ISA’s leadership holds favorable views of mining.
Advocates welcome halt to shortfin mako shark fishing, call for longer ban
- Nations have agreed to effectively ban the fishing of endangered shortfin mako sharks in the North Atlantic from 2022 to 2023.
- Conservationists say the retention ban — which means fishers will not be allowed to land the sharks, even those caught accidentally — is a positive step, but that it’s too short to adequately help the species recover.
- It’s estimated that shortfin mako shark populations in the North Atlantic will decline by 60% over the next decade.
‘Our land, our life’: Okinawans hold out against new U.S. base in coastal zone
- Opponents of the planned relocation of a U.S. military base in Okinawa say they remain undeterred despite the defeat in elections last month of the opposition party that supported the cause.
- Local activists plan to continue opposing the relocation of the Futenma Marine base, from the densely populated city of Ginowan to the less crowded Henoko Bay coastal area.
- The proposed new facility and other military bases in Okinawa have been linked to toxic environmental pollution, military-linked sexual violence, and historical land conflicts between native Okinawans and the mainland Japan and U.S. governments.
- The Okinawa prefecture government recently rejected central government plans to sink more than 70,000 compacting pillars into Henoko’s seabed for construction, which would impact coral and seagrass that host more than 5,000 species of marine life.
If marine noise pollution is bad, deep-sea mining could add to the cacophony
- A new report suggests that the noise pollution produced by deep-sea mining activities could have far-reaching effects on the marine environment, from surface to seafloor.
- While there are many studies that measure the impacts of noise pollution on marine life, more research is needed to fully understand how sound from deep-sea mining could affect the ocean.
- Due to the paucity of information, experts say a precautionary approach to deep-sea mining noise is required and that clear regulations must be put into place by the International Seabed Authority.
- While deep-sea mining has yet to begin, a subsidiary of Canada-based The Metals Company plans to start mining in less than two years.
Countries fail to agree on Antarctic conservation measures for fifth straight year
- Members of the multilateral body responsible for Antarctic marine conservation failed to agree on new measures to protect the Southern Ocean from overfishing.
- China and Russia blocked all proposals to establish new marine protected areas.
- This story was originally published by the Environmental Reporting Collective.
Hospital waste, not masks, are plastic scourge of pandemic: Study
- A new study has found that 26,000 metric tons of pandemic-related plastic waste has been released into the world’s oceans since the start of the COVID-19 pandemci in January 2020.
- The largest share by far of pandemic-related plastic waste is generated by hospitals, while comparatively smaller amounts are from the improper disposal of face masks, COVID-19 testing kits, and packaging from online shopping activity.
- Besides posing a threat to marine life and humans, mismanaged plastic waste may have the potential to alter Earth’s life-support systems, its dynamics and stability, researchers say.
- Plastic is one of many human-made materials included in the “novel entities” planetary boundary, which is one of nine thresholds beyond which life on Earth could become untenable.
Despite deals, plans and bans, the Mediterranean is awash in plastic
- The Mediterranean is considered to be one of the world’s most polluted bodies of water due to waste disposal problems in many countries bordering the sea, as well as the intensity of marine activity in the region.
- There are several existing policies and treaties in place aimed at regulating plastics and reducing plastic pollution in the Mediterranean, but experts say more international cooperation is needed to tackle the problem.
- Citizen science organization OceanEye has been collecting water samples to measure the amount of microplastics present in the surface waters of the Mediterranean.
New protections announced for Galápagos Islands and beyond at COP26
- Ecuador’s president announced on Nov. 1 an expansion of the existing Galápagos Islands marine reserve to encompass an additional 60,000 square kilometers (23,200 square miles).
- The majority of the addition would be established across the Cocos Ridge, which is an important migration route for species like hammerhead sharks and leatherback turtles.
- The following day, the presidents of Ecuador, Panama, Colombia and Costa Rica also announced that the four countries intended to create a large marine corridor between their four countries by extending and joining their current marine protected areas.
- Experts say that the new Galápagos marine reserve, in conjunction with the larger corridor, would help protect a range of migratory species.
As seizures of poached giant clams rise, links to ivory trade surface
- A new report released by the Wildlife Justice Commission identifies the giant clamshell trade as a “cause for concern.”
- It suggests the trade could have links with organized crime, and that it could also be endangering elephants since clamshells are a viable substitute for elephant ivory.
- China and Japan are noted as potential markets of concern in the giant clamshell trade.
- Very little is known about the giant clamshell trade, which has prompted experts to call for more investigations into the issue.
Experts see no way back for NZ firm blocked from trying to mine the seabed
- The New Zealand Supreme Court recently blocked consent for a seabed mining operation that would annually extract 50 million tons of iron ore from the seabed off the coast of South Taranaki.
- Environmentalists see this decision as a clear victory, but the mining company has stated its intention to reapply for mining permission.
- But experts say it’s unlikely the company, Trans-Tasman Resources Limited (TTR), will be able to regain consent due to fundamental issues with its application, such as the distinct lack of baseline studies on resident marine life and the potential impacts of mining.
- Conservationists say seabed mining in this part of New Zealand would cause irreversible damage to the ecosystem and threaten many rare and endangered species.
With coral cover halved, curbing climate change is only way to slow the loss
- A new study estimates that global coral cover is half what it was in the 1950s, with much of that loss linked to human-driven climate change.
- The shrinking of coral cover has translated into a 60% loss in reef biodiversity.
- Reef fish catches peaked in 2002 and have been declining ever since, taking a toll on coastal populations, especially Indigenous communities who are more dependent than non-Indigenous communities on seafood.
- Some of these threats are being tackled at the level of communities and even countries, but it may not be enough given the global nature of the biggest threat.
Deep-sea mining gets a resounding rejection from conservation authorities
- Members of the IUCN World Conservation Congress have voted overwhelmingly in support of a moratorium on deep-sea mining, an activity that conservationists say could cause irreversible damage to the ocean.
- The South Pacific nation of Nauru recently triggered a two-year rule, which would require the International Seabed Authority (ISA) to grant it a license to begin mining under whatever regulations are in place by then.
- Conservationists say there is currently little to no understanding of how deep-sea mining could negatively affect the deep-sea environment.
On board Ghana’s trawlers, claims of human rights abuses and illegal fishing
- A report and video published by the Environmental Justice Foundation describes a range of human rights abuses experienced by fisheries crew members and official observers on board industrial vessels operating in Ghana’s waters.
- According to the report, most of these vessels are involved in illegal fishing practices, including the use of undersized nets, the catching and dumping of juvenile fish, and the transshipment of large quantities of pelagic fish that should be reserved for artisanal fishers, which is helping to push Ghana’s fishery to the point of collapse.
- Human rights abuses are prevalent on industrial fishing vessels across the world, and tend to be entwined with issues of illegal, unreported and unregulated (IUU) fishing.
- While many experts validate the allegations of human rights abuse in the report, some in positions of power suggest the issues aren’t as straightforward as they might appear.
Geopolitical standoff in South China Sea leads to environmental fallout
- Satellite images show significant growth in the occurrence of algal blooms in contested areas in the South China Sea.
- Images suggest that these algal blooms or phytoplankton overgrowth are linked to the presence of vessels anchored in the area and to island-building activities in the region.
- While satellite images help give a preview of the ecological state of the South China Sea, on-site observations are necessary to validate the findings, experts say.
- Decades of territorial and maritime disputes, however, have limited the conduct of studies and dissuaded the establishment of conservation zones in the South China Sea.
Drive toward green cars shouldn’t rely on mining seabed, conservationists say
- Conservationists are urging electric car and technology companies not to support or use resources derived from deep-sea mining, an activity that could potentially cause irreparable damage to the marine ecosystem in the process.
- The burgeoning electric car industry relies on a number of minerals for batteries, including lithium, manganese, nickel and cobalt, which are not easily accessible from terrestrial sources.
- Deep-sea mining proponents say that mining polymetallic nodules offers an alternative way to procure much-needed minerals for electric car batteries, but conservationists argue that the risks are too great to ignore.
- Instead of mining the deep sea, conservationists say that the focus should shift to developing electric car batteries that do not require hard-to-get minerals, improving terrestrial mining practices, and expanding battery recycling.
Building back Miami’s Biscayne Bay: Do natural solutions hold hope?
- A massive fish kill in August 2020 was a red flag that historically troubled Biscayne Bay in Miami had passed a biodiversity health tipping point.
- Years of scattered efforts and mixed results of various conservation actors working toward the bay’s recovery have begun to fade in favor of more collaborative, inclusive efforts.
- Scientists and citizens are now focusing their efforts on creative ways to restore biodiversity in Biscayne Bay.
Seafloor microbes hoover up methane, keeping global warming in check
- A new study found that carbonate rock mounds on the ocean floor host communities of microbes that actively consume methane, a greenhouse gas that is particularly potent if released into the atmosphere.
- The researchers found that rock-inhabiting microbes consumed methane 50 times faster than microbes that live in sediment.
- These microbes therefore play a crucial role in regulating the Earth’s temperature by consuming methane before it travels up into the water column and into the atmosphere.
Billions in fishing subsidies finance social, ecological harm, report finds
- A new report found that the world’s top 10 fishing nations are spending billions of dollars on harmful fishing subsidies to not only exploit their own domestic waters, but to fish in the high seas and the waters of other nations.
- Experts say these subsidies are propping up fishing industries that would not be viable without financial support, and contributing to overcapacity, overfishing, and illegal, unreported and unregulated (IUU) fishing.
- The report also found that harmful fishing subsidies could also be leading to food security issues in some of the world’s least-developed countries where foreign fleets surpass domestic fleets in terms of subsidies and catches.
- The issue of harmful fishing subsidies will be addressed at an upcoming meeting of the World Trade Organization (WTO) that will take place online on July 15.
Nauru’s intention to mine the seabed prompts alarm among conservationists
- Nauru has notified the International Seabed Authority (ISA) that its sponsored entity, Nauru Ocean Resources Inc. (NORI), plans to commence deep-sea mining in two years’ time, triggering a two-year rule embedded in the U.N. Convention on the Law of the Sea.
- The ISA has yet to generate a mining code that would set out rules and regulations for deep-sea mining activities.
- Experts are concerned that the ISA will prematurely approve Nauru’s application and that deep-sea mining will commence before we fully understand the damage it could cause to biodiversity and ecosystems.
With growing pressures, can the Philippines sustain its marine reserves?
- The Philippines pioneered a community-based approach to marine protected area management in 1974, which balanced conservation and community livelihood. This became the blueprint of the more than 1,500 marine reserves in the country today.
- While the government depends on its MPA system in protecting its seascapes and meeting its international commitments, research suggest only a third of the country’s MPAs are well-managed and only protect around 1% of the country’s coral reefs.
- With management and resource challenges, these MPAs are threatened by overfishing and illegal fishing practices as well as the worsening impacts of climate change.
- Experts say strengthening the country’s larger MPA systems, synchronizing conservation with fisheries management policies, adapting newer models, and creating a network of MPAs may help the country buffer the impacts of climate change on its rich marine resources.
Climate change isn’t fueling algal blooms the way we think, study shows
- A team of international researchers recently published the first global assessment of harmful algal blooms (HABs) — events in which toxic algae proliferate and cause harm to marine life and humans — based on nearly 10,000 recorded events between 1985 and 2018.
- The study found that there are no global trends that would suggest that climate change is having a uniform impact on HABs throughout the world, although this is a commonly held belief.
- The researchers were able to detect clearer regional trends that showed increases, decreases or no significant changes in HABs in certain parts of the world.
- It also found that there was a perceived increase in HABs amid the booming aquaculture industry, although the study does not necessarily suggest that aquaculture is causing an increase in HABs.
‘Dark’ ships off Argentina ring alarms over possible illegal fishing
- A new report from the NGO Oceana revealed that 800 foreign vessels from China, Taiwan, South Korea and Spain conducted 900,000 hours of visible fishing near Argentina’s exclusive economic zone (EEZ), but that there were more than 600,000 additional hours in which fishing vessels went “dark” by turning off their automatic identification systems (AIS).
- When ships turn off their AIS, there is a strong likelihood that they’re engaging in some kind of illegal activity, such as entering Argentina’s EEZ to illegally fish, the report suggests.
- While China had the highest number of incidences of AIS gaps, the report notes that the Spanish fleet went dark three times as often as the Chinese fleet, and that they spent nearly twice as long with no AIS signal as they did visibly fishing.
- The report also documents that more than 30% of dark vessels eventually traveled to the Port of Montevideo in neighboring Uruguay, a location favored by those involved in illegal fishing. It also notes that more than half of the dark vessels engaged with other ships at sea, most likely to transfer illegally caught fish without needing to go to port.
Talks break down over crumbling Yemeni tanker threatening massive oil spill
- The FSO Safer, an oil supertanker anchored for decades off Yemen, risks a catastrophic humanitarian and environmental disaster in the Red Sea.
- The civil war in Yemen has suspended essential maintenance on the increasingly fragile vessel with more than 1 million barrels of oil in its hold and hindered disaster preparedness.
- On June 1, talks appeared to break down between the U.N. and the Houthi administration, which controls the vessel. The two sides had spent months negotiating access for a U.N. team to investigate and stabilize the vessel.
- A spill would jeopardize corals with the best-known chance of surviving predicted global climate change.
With fire contained, Sri Lanka faces plastic pellet problem from stricken ship
- Sri Lanka faces an uphill task to clean up countless plastic pellets that have washed up on its beaches from a cargo ship that caught fire off the island’s west coast.
- The fire, linked to the X-Press Pearl’s cargo of nitric acid, was brought largely under control by May 30 after it broke out on May 21, authorities say.
- The plastic pellets, or nurdles, that fell overboard during the incident have spread with the ocean current down to southern Sri Lanka, carpeting beaches along the coast and posing a threat to marine life and humans.
- Experts say the cleanup operation will be long and difficult, given the scale of the problem and the fact that Sri Lanka is under a COVID-19 lockdown that limits the mass mobilization needed to mount a cleanup effort.
Satellites keep watch over global reef health in a world first
- Scientists working with the Allen Coral Atlas just launched the world’s first global, satellite-based reef-monitoring system.
- This tool can track global coral bleaching events in near-real-time and provide an overall view of trends and changes in coral reef health that can be used to inform conservation efforts and policy.
- A beta version of the system that was piloted in Hawai‘i during the 2019 Pacific heat wave, and helped identify bleaching hotspots as well as resilient corals that could be used for reef restoration.
Arctic biodiversity at risk as world overshoots climate planetary boundary
- The Arctic Ocean biome is changing rapidly, warming at twice the rate of the rest of the world. In turn, multiyear sea ice is thinning and shrinking, upsetting the system’s natural equilibrium.
- Thinner sea ice has led to massive under-ice phytoplankton blooms, drawing southern species poleward; fish species from lower latitudes are moving into the peripheral seas of the Arctic Ocean, displacing and outcompeting native Arctic species.
- Predators at the top of the food chain, such as polar bears, are suffering the consequences of disappearing ice, forced onto land for longer periods of time where they cannot productively hunt.
- The Central Arctic Ocean Fisheries Agreement has been signed by 10 parties to prevent unregulated commercial fishing in the basin until the region and climate change impacts are better understood by scientists. International cooperation will be critical to protect what biodiversity remains.
Study calls for a marine reserve in a $500m fishing hotspot in Indonesia
- A new study proposes establishing a marine protected area in Indonesia’s Java Sea-Makassar Strait region, one of the top fishing grounds in the country.
- The study found that much of the commercially valuable snapper and grouper species caught in these shallow waters are juveniles, which compromises the sustainability of the species’ populations and of the $500 million fishery itself.
- Another expert says imposing an MPA in this key fishing area would be a bureaucratic challenge, and instead suggests introducing an annual close season, similar to the one for yellowfin tuna in Indonesia’s Banda Sea.
- The study authors have also called for a change in consumer behavior, noting that the desire for snappers that fit on a plate is what drives the fishing of juveniles.
‘Minke whales for dinner’: Norway’s controversial whale hunt is still on
- Norway has announced that it will target up to 1,278 common minke whales in its upcoming whaling season, which is the same quota as the past two years.
- While the Norwegian government says its whaling program is sustainable, some scientists, conservationists and animal welfare experts counter this claim.
- These anti-whaling advocates also point to a growing body of evidence that suggests that whales play a pivotal role in regulating the marine ecosystem, and that whales are worth more alive than dead.
- There has been a global moratorium on commercial whaling since 1986, but Norway chooses to reject this ban.
Declaring key ocean habitats off-limits to human activities protects biodiversity and guards against climate change (commentary)
- Oceans around the world face a litany of threats, from climate change to overfishing to pollution and more.
- Marine protected areas (MPAs), when well-sited, well-managed and durable, provide ocean ecosystems with the capacity to restore damaged marine populations, protect endangered species and recover faster from climate-caused disasters.
- MPA policies need to be implemented more widely, writes Kelsey Lamp from Environment America’s ocean campaigns, starting by protecting 30% of our oceans with MPAs by 2030.

U.N. report lays out blueprint to end ‘suicidal war on nature’
- According to a new report from the United Nations Environmental Programme, the world faces three environmental “emergencies”: climate change, biodiversity loss, and air and water pollution.
- U.N. Secretary-General António Guterres said we should view nature as “an ally,” not a foe, in the quest for sustainable human development.
- The report draws on assessments that quantify carbon emissions, species loss and pollutant flows to produce what the authors call concrete actions by governments, private companies and individuals that will help address these issues.
In the fight to save the vaquita, conservationists take on cartels
- The critically endangered vaquita porpoise, a species endemic to the Sea of Cortez in the Upper Gulf of California in Mexico, is at severe risk of extinction due to illegal gillnet fishing for the critically endangered totoaba fish.
- Andrea Crosta of Earth League International (ELI) says the key to saving the species is arresting all criminals involved in the illegal totoaba trade, while other NGOs work to patrol the Sea of Cortez for illegal gillnet use or to introduce seafood sanctions.
- With only nine vaquita porpoises believed to be left in the world, most experts agree that this year will be critical to the vaquita’s survival.
Fewer than 100 of these giant whales make up a newly described species
- In January scientists announced the designation of a new whale species in the Gulf of Mexico they named Rice’s whale (Balaenoptera ricei).
- The team previously collected genetic samples of the whales but didn’t confirm the new species until they had a complete skeleton.
- Only between 33 and 100 individual members of the species exist, researchers estimate. The species is listed as endangered in the U.S.
- The Gulf of Mexico is fraught with many human-made threats to the whales’ survival, including dense ship traffic, oil and gas exploration, and marine trash.
New study warns that sea levels will rise faster than expected
- A new study has found that sea level rise may happen faster than current models project.
- The Intergovernmental Panel on Climate Change (IPCC) projects that the sea level will rise about a meter (39 inches) by the century’s end, but this study finds that estimate to be conservative.
- The results suggest that sea levels will rise about 25 centimeters (10 in) more per century if carbon emissions are not curbed and the Earth continues to heat up.
Activists make the case that bigger is better to protect Galápagos reserve
- A group of scientists, conservationists and NGOs are campaigning to expand the current Galápagos Marine Reserve to protect an additional 445,953 square kilometers (172,183 square miles) in the exclusive economic zone of the Galápagos Islands.
- According to a scientific proposal, the marine reserve expansion would help protect threatened migratory species, deter unsustainable and illegal fishing practices, and even bolster the legal Ecuadoran fishing industries.
- While the proposal has garnered both national and international support, Ecuador’s fishing sector is largely opposed to the expansion of the reserve.
Frustration as Antarctic conservation summit fails to declare marine sanctuaries
- A proposition to establish three new marine protected areas (MPAs) in East Antarctica, the Antarctic Peninsula and the Weddell Sea was not approved at a recent meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which was held online in the last week of October.
- Conservation experts who attended the meeting reported there was limited time for negotiations, and that discussions focused more on fishing renewal authorizations and the issue of a Russian vessel suspected of illegally fishing, rather than the MPA designations and climate change action.
- On the other hand, many delegates signed a pledge of support for the formation of the three MPAs, and the Weddel Sea MPA and East Antarctica MPA gained new co-sponsors.
Efforts to tackle shark fin trade need to focus closer to shore, study says
- A new study has found that shark fins being sold in Hong Kong, Vancouver, San Francisco and northern Brazil originated mostly from shark species in coastal waters, rather than the open ocean.
- The research team analyzed 500 shark fin samples using DNA barcoding techniques, and generated species distribution models to illustrate the areas in which these sharks were likely fished.
- While these findings can help focus conservation efforts in coastal regions, they can also introduce new challenges with fishing vessel monitoring efforts, the team says.
‘No other choice’: Groups push to protect vast swaths of Antarctic seas
- A coalition of conservation groups is advocating for the establishment of three new marine protected areas (MPAs) in East Antarctica, the Antarctic Peninsula and the Weddell Sea, which would encompass 4 million square kilometers (1.5 million square miles) of the Southern Ocean, or 1% of the global ocean.
- These proposals will be discussed at an upcoming meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which is due to take place online because of the pandemic.
- Conservationists anticipate that China and Russia may not support these MPA proposals due to fishing interests in the region, although they are optimistic that the MPAs will eventually be approved.
New evidence suggests China’s ‘dark’ vessels poached in Galápagos waters
- A fleet of Chinese-owned fishing vessels crowded along the edge of Ecuador’s exclusive economic zone (EEZ) near the Galápagos Islands between June and September, prompting international concern that they would illegally fish in Ecuador’s territorial waters.
- Several vessels turned off their GPS-based automatic identification systems (AIS), possibly to avoid discovery while partaking in illegal activities, several sources found.
- An analysis of new data, this time from radio signals, not GPS, detected unidentified ships within the Galápagos EEZ, with several of the boats operating immediately adjacent to the Chinese fleet.
- The new data provide additional, but still inconclusive, evidence that the Chinese fleet may have entered Ecuador’s EEZ.
Blooms driven by climate change threaten to smother marine life in Arabian Sea
- A strange single-celled organism that acts both as a plant and an animal has come to dominate wintertime algal blooms in the northern Arabian Sea.
- Winter blooms of Noctiluca scintillans, also known as the sea sparkle, have displaced microscopic algae called diatoms that form the basis of the marine food chain, a paper in Nature says.
- Scientists at Columbia University fear the outbreaks could herald massive declines in fisheries in the region, potentially impacting millions of fishers in India, Pakistan, Iran, Oman and Yemen.
- They have linked the emergence of N. scintillans blooms with the loss of ice cover in the Himalayan-Tibetan Plateau driven by climate change.
Flip-flops, fishing gear pile up at Aldabra, a UNESCO World Heritage Site
- More than 370,000 flip-flops from all over the world are piling up on the Aldabra coral atoll In Seychelles, one of the remotest corners of the planet and a UNESCO World Heritage Site, according to a new study.
- The second-largest atoll in the world, with a vast lagoon enclosed by raised coral atolls, Aldabra is home to the India Ocean’s last giant tortoises and only flightless bird species, among other rare and threatened wildlife.
- The authors of the new paper estimate that plastic garbage from fishing vessels accounts for more than 80% of the trash on the atoll by weight.
- They calculate that recovering the plastic trash on Aldabra could cost as much as $7.3 million, a large price to pay for a small island nation like Seychelles.
Birthday party on ship may have led to oil spill in Mauritius, Panama regulator says
- A Japanese ship that ran aground on a coral reef off Mauritius may have changed course to get a mobile data signal for a birthday celebration on board, according to investigators from Panama, the country under whose flag the vessel was sailing.
- The M.V. Wakashio crashed into the coral reef barrier on July 25 and leaked almost 1,000 tonnes of fuel oil into Mauritian waters.
- The vessel’s captain was taken into custody on Aug. 18 for endangering safe navigation as Mauritian authorities said the ship failed to respond to several calls from the Mauritian Coast Guard.
- Mitsui O.S.K. Lines (MOL), the Japanese company operating the ship, has pledged 1 billion yen ($9.5 million) for environmental preservation efforts and to shore up local fisheries.
In Indonesia’s coastal villages, the plastic crisis is both homegrown and invasive
- Proper management of plastic waste is lacking in Indonesia’s coastal communities, where the use of plastics is outpacing mitigation efforts, according to a newly published study.
- The paper found that nearly 6,700 households in the Selayar and Wakatobi island chains had relatively low knowledge about plastic and how to manage it properly, while their use of it, particularly, single-use plastic packaging, was growing.
- The researchers have called for producers to take greater responsibility for managing the waste generated by their products, and for a transition to a circular economy.
- Indonesia is the second-biggest contributor of the plastic waste in the world’s oceans, behind only China.
Mauritians take to the street over oil spill and dolphin and whale deaths
- People gathered in the thousands in Mauritius’s capital, Port Louis, to protest the government’s response to a recent oil spill.
- The Japanese-owned freighter M.V. Wakashio crashed into the coral reef barrier off the island’s southeastern coast on July 25 and leaked about 1,000 tons of fuel oil into the sea near ecologically sensitive areas, before breaking in half a few weeks later.
- The stranding of at least 39 dolphins and whales near the site has sparked an outcry, though a link between the Wakashio shipwreck and the beachings has not yet been established.
- In a controversial move, the Mauritian government decided to sink the front half of the ship several kilometers away from the crash site in open waters, which some experts say could have impacted the dolphin and whale populations.
Mauritius grapples with worst environmental crisis in a generation
- A ship that ran aground on a coral reef has leaked about 900 tons of fuel oil into the waters off the southeastern coast of Mauritius.
- The incident occurred on July 25, and by Aug. 6 the Japanese-owned ship started to spill oil from its fuel tank, leading Mauritian authorities to declare an environmental emergency.
- The oil sludge threatens Pointe d’Esny, the largest remaining wetland in Mauritius, and other ecologically sensitive areas like the Ile aux Aigrettes Nature Reserve, Blue Bay Marine Area, and Mahebourg Fishing Reserves.
- Water currents appear to be carrying the oil slick north along the eastern shoreline, putting mangrove forests in harm’s way.
App harnesses citizen power to keep tabs on Philippines’ coral reefs
- A series of coral bleaching events have affected reefs across the Philippines in previous years, and this year alone 11 such incidents have been reported.
- But bleached reefs aren’t necessarily dead, with some still able to recover if they are resilient enough and if no further stressors come into play.
- Given that the Philippines has an estimated 33,500 square kilometers (nearly 13,000 square miles) of reefs, a volunteer group is relying on a small but growing army of citizen scientists to keep track of these bleaching incidents by submitting photos online or through an app.
- Citizen science could also help identify other threats to coral reefs, including crown-of-thorns infestation and disease outbreaks, as well as identify corals that are more resilient.
Sharks are ‘functionally extinct’ in many global reef systems, study finds
- A new study surveyed 371 coral reefs in 58 countries, and found sharks were virtually absent from 20% of the surveyed reefs, indicating that they were functionally extinct from these ecosystems.
- The research team collected 15,165 hours of video via baited remote underwater video stations (BRUVS), and used this data to analyze shark abundance on global reef systems.
- The absence of sharks was usually connected to poor governance of nearby human settlements, including unregulated and destructive fisheries.
- While sharks were missing from many reefs around the world, other locations boasted healthy shark populations due to rigorous conservation efforts.
In picturesque Boracay, a crown-of-thorns infestation is eating away at the reef
- The coral reef surrounding the resort island of Boracay, which the Philippine government wants to reopen to tourists, is under attack from a crown-of-thorns starfish infestation.
- Local officials receiving reports of a possible outbreak weren’t able to confirm for four months because of the COVID-19-related lockdown, and were only allowed to dive in early July.
- A similar outbreak occurred in 2018, which prompted officials to tap volunteer divers to help collect the crown-of-thorns.
- But with the pandemic and lockdown, officials are short of volunteer divers and are considering training fisherfolks to help save Boracay’s coral reefs.
‘Our life is plasticized’: New research shows microplastics in our food, water, air
- Microplastics, plastic pieces smaller than 5 millimeters, have become increasingly prevalent in the natural world, and a suite of studies published in the last three years, including several from 2020, shows that they’ve contaminated not only the ocean and pristine wildernesses, but the air, our food, and even our bodies.
- Past research has indicated that 5.25 trillion plastic pieces are floating in the ocean, but a new study says that there are 2.5 to 10 times more microplastics in the ocean than previously thought, while another recent study found that microplastic “hotspots” could hold 1.9 million pieces per square meter.
- Other emerging research suggests that 136,000 tons of microplastics in the ocean are being ejected into the atmosphere each year, and blowing back onto land with the sea breeze, posing a risk to human health.
- Microplastics are also present in drinking water, and edible fruits and vegetables, according to new research, which means that humans are ingesting microplastics every day.
Oil slick threatens Philippine mangrove forest recovering from earlier spill
- An explosion aboard a power barge off the Philippine island of Guimaras has spilled up to a quarter million liters of fuel oil, threatening local communities and mangrove and seagrass habitats.
- The barge operator, AC Energy Inc., says the cleanup could take two weeks; local disaster mitigation officials say more than 300 families are affected and have ordered an evacuation.
- The mangroves off Guimaras were affected by the Philippines’ biggest ever oil spill in 2006, when an oil tanker sank, spilling half a million liters of fuel and affecting 648 hectares (1,600 acres) of mangrove forests and seagrass areas, which are only now recovering.
- Officials are conducting cleanup efforts to keep the latest oil spill away from the recovering mangrove swamps.
Deep-sea mining: An environmental solution or impending catastrophe?
- A new report by the Deep Sea Mining Campaign and MiningWatch Canada examines the potential risks of seabed mining operations targeting polymetallic nodules: rock concretions that harbor minerals like manganese, nickel, cobalt and copper.
- While deep-sea mining has not started in any part of the world, 16 international mining companies have contracts to explore the seabed for minerals within the Clarion Clipperton Zone (CCZ) in the Eastern Pacific Ocean, and other companies have contracts to explore for nodules in the Indian Ocean and Western Pacific Ocean.
- The report suggests that polymetallic nodule mining would negatively impact ecosystems, biodiversity, fisheries, and the social and economic dimensions of Pacific island nations, and that this mining requires a precautionary approach. Mining companies, on the other hand, say nodule mining is less destructive than land mining, and that mining operations can benefit Pacific island nations socially and economically.
- Mining companies also say polymetallic nodule mining is necessary to provide the minerals needed for renewable energy technologies, while opponents say these minerals can be extracted from land sources, including recycled electronics.
Scientists agree on the need to protect 30% of the seas. But which 30%?
- Scientists recommend protecting at least 30% of the ocean by 2030 to safeguard biodiversity, avoid fishery collapse and build ocean resistance to climate change.
- In 2018 and 2019, representatives from the United Nations were negotiating a high seas treaty to meet this goal through a network of marine protected areas (MPAs) throughout the open ocean, but the meeting meant to finalize the treaty in March was delayed due to COVID-19.
- Two reports were presented to show how to practically protect 30% of the ocean: one from a group of researchers from University of Oxford, the University of York and Greenpeace, and the other from the University of California, Santa Barbara, and other universities and institutions.
- The two reports used different methodologies and had slightly different results, but they also showed considerable overlap in their recommendations of safeguarding certain areas of biological and ecological importance.
Economists put a price tag on living whales in Brazil: $82 billion
- Last year, a team of four economists published a report suggesting that living whales have a high market value for the services they provide in terms of ecotourism, carbon sequestration, and fishery enhancement. Each whale is worth about $2 million USD, they estimated.
- The economists, in collaboration with two conservation organizations, Instituto Baleia Jubarte and the Great Whale Conservancy, estimated that Brazil’s whale population is worth $82 billion.
- The team says it hopes the notion of valuing whales in Brazil, as well as in other coastal nations, can help protect whales from common fatalities like ship strikes, fishing gear entanglement, and deliberate hunting.
Satellite imagery is helping to detect plastic pollution in the ocean
- A new study illustrates how optical satellite imagery from the European Space Agency can be used to identify aggregates of floating plastic, such as bottles, bags and fishing nets, in coastal waters.
- The researchers tested their methods at four main locations — Accra, Ghana; the San Juan Islands, U.S.; Da Nang, Vietnam; and east Scotland — and reported an 86% success rate.
- It is estimated that more than 8.3 billion tons of plastic waste enter the oceans each year, threatening global ocean health.
Decade after BP Deepwater Horizon spill, oil drilling is as dangerous as ever
- Ten years ago, the BP Deepwater Horizon exploratory rig exploded, killing 11 people and initiating the largest oil spill in the history of the United States.
- Nearly 5 million barrels of oil spilled into the Gulf of Mexico, causing catastrophic damage to the ecosystem and economy of the region.
- A newly published report by the nonprofit Oceana looks back at how this spill happened, the resulting ecological and economic impacts, and if this catastrophe has changed government or oil industry approaches to offshore drilling.
- Poor government oversight and inadequate safety culture paved the way for the BP Deepwater Horizon explosion. Now, a decade later, it appears these conditions, the prerequisites for disaster, have not improved.
Ocean optimism: Study says we can restore marine health
- A new study finds that it’s possible to repair the world’s oceans to a substantial level in three decades, as long as appropriate measures are taken to protect vulnerable marine species and habitats, rebuild damaged ecosystems, and alleviate the pressures of climate change.
- Several models of success are used to demonstrate that repairing the oceans is a realistic goal, including the positive impacts of wildlife trade and hunting regulations to protect endangered species and critical habitats.
- The biggest challenge in reinstating global ocean health is mitigating the effects of climate change, the authors say.
Great Barrier Reef suffers biggest bleaching event yet
- Australia’s Great Barrier Reef just experienced its third major bleaching event in the past five years, which has caused severe and widespread damage.
- The Australian Bureau of Meteorology (BOM) recorded its highest ever sea temperature this past February, which triggered the bleaching.
- The southern part of the reef, which remained relatively untouched during large bleaching events in 2016 and 2017, suffered the most acute damage this time.
- While some corals are able to recover from bleaching, this process can take more than a decade, and scientists fear the Great Barrier Reef won’t recover.
In race for a sustainable alternative to plastic, Indonesia bets on seaweed
- A local government initiative to revive seaweed farming off Bali comes amid growing interest in the crop’s promise to tackle environmental problems ranging from carbon emissions to plastic waste pollution.
- Cultivated at scale, seaweed can grow up to 60 times faster than land-based plants, making it an important carbon sink.
- Local startups are also exploring its potential to make bioplastic that is naturally degradable and even edible, for use in food packaging and other applications to replace plastic.
- For the new generation of seaweed farmers in Indonesia, the plant also offers revenue streams through ecotourism.
This solar-powered device aims to clean 1,000 rivers. Will it work?
- In October, Dutch nonprofit The Ocean Cleanup (TOC) unveiled a solar-powered river-cleaning device called the Interceptor.
- The organization plans to deploy the devices in 1,000 of the world’s most polluting rivers in just five years to stem the flood of plastic entering the ocean.
- Mongabay visited the prototype operating in Jakarta’s heavily polluted Cengkareng drain in February and found it stalled after a heavy rain.
- The designer of a similar device says TOC copied his company’s design and is attempting to interfere with its partnerships. A TOC representative denied the allegations and said lessons learned from the Jakarta prototype have led to adjustments to the second generation of Interceptors.
Plastic trash kills half a million hermit crabs on remote islands each year
- An estimated 570,000 hermit crabs become trapped and die in plastic containers on the remote Cocos (Keeling) Islands and Henderson Island each year, according to a new study.
- Accumulated plastics on beaches could cause a serious decline in hermit crab populations, the study’s authors say.
- Hermit crabs are at risk on beaches globally where crabs and plastic pollution overlap.
In Bali, young people lead the fight as a plastic plague threatens paradise
- The lack of a centralized waste management system in Bali, as in much of Indonesia, has led to most trash being dumped on land, rivers, and in the sea.
- Indonesia is the world’s No. 2 contributor to the plastic waste in the oceans, behind only China.
- In Bali, the fight against plastic waste is being spearheaded by local organizations, communities and youth groups, who have already convinced the local government to ban single-use plastics.
- The groups are pushing for a greater role by the government, particularly to centralize the waste collection and processing system.
The ‘blue acceleration’: Study shows humans’ surging incursions into the sea
- Population growth and demand for diminishing terrestrial resources are placing increasing pressure on the ocean.
- A new study highlights a sharp uptick in marine activity and defines the “blue acceleration” as the unprecedented rush for food, material and space taking place in the ocean.
- “[T]he ocean is not only crucial for sustaining global development trajectories but is being fundamentally changed in the process,” the study authors write.
Illegal industrial fishing hampers small-scale African fisheries
- A new analysis shows that industrial fishing fleets operating in the waters of African countries and territories spend an average of nearly 6% of their fishing effort inside zones set aside for small-scale fisheries.
- In some countries, foreign fleets spend the bulk of their time — more than 90% in Somalia, for example — within the prohibited zone.
- Communities along Africa’s coasts are often dependent on fish as a source of food and protein.
- But incursions by large-scale fishing vessels, called “the most common form of illegal fishing in the region,” can threaten the sustainability of the resource, create conflict over it, and endanger the lives of fishers themselves.
Key cetacean site in Philippines sees drop in dolphin, whale sightings
- A recent survey has confirmed a declining trend in sightings of dolphins and whales in the Tañon Strait in the central Philippines, a waterway declared an Important Marine Mammal Area by the IUCN.
- The strait is a migratory route for at least 11 cetacean species, including the vulnerable Gray’s spinner dolphin and the endangered false killer whale, but four surveys carried out since 1999 have shown a sharp decline in population and species sightings.
- One bright spot in the latest survey was the sighting of rose-bellied dwarf spinner dolphins, only the second time that the species has ever been spotted in Philippine waters.
- The strait is one of the country’s busiest sea lanes, encountering heavy fishing and tourism activities, which researchers say may be a factor for the downward trend. They call for further collaboration to enact stringent measures on fishing and tourism activities to protect the area.
Philippine coastal town leads war against plastic trash in Mindanao
- The town of San Isidro in Mindanao committed to eliminating plastic pollution in ten years after locals experienced repeated cases of rescuing sea turtles that eventually die with stomachs full of plastic wastes.
- The anti-plastic campaign comes at a time that the Philippines is struggling with solid wastes, particularly plastic, in its waters that endanger its rich marine life.
- The town is engaging the community by paying for collected plastic wastes, teaching financial literacy to children, and turning these wastes into “eco-bricks” for use in local construction.
- More stringent waste management policies are also being adopted, including requiring climbers who visit Mt. Hamiguitan, a UNESCO world heritage site, to carry their wastes out instead of leaving it in the mountain.
Nearly extinct vaquita mothers with calves spotted in recent expeditions
- The latest expeditions in the Gulf of California, Mexico, to survey the vaquita, the world’s smallest cetacean, have yielded sightings of both vaquita mothers and calves. This, researchers say, indicates that the mammals are still reproducing despite threats.
- In a survey carried out between August and September, researchers spotted what they say were likely six distinct individual vaquitas.
- During a subsequent expedition in October, researchers say they spotted vaquitas several times, including six different vaquitas in two groups, and three pairs of mothers and calves.
- This news is hopeful, but the mammal’s future is still perilous due to the continued use of illegal fishing nets in its habitat, experts say.
Coal spill bedevils Indonesian beach more than a year later
- Coal from a barge that spilled onto a beach in Indonesia’s Aceh province in July 2018 still hasn’t been fully cleaned up.
- Lampuuk Beach, on the northern tip of Sumatra, is hosting a surfing championship this weekend, but participants and residents say that coal continues to litter and contaminate the site.
- The coal was destined for a power plant run by a cement producer, which had experienced an identical spill in 2016 at a nearby beach.
- While authorities have ordered the cement producer to clean up the site, the company says the barge operator should be held responsible.
’Rampant’ fishing continues as vaquita numbers dwindle
- An expedition surveying the Gulf of California for the critically endangered vaquita porpoise has reported seeing more than 70 fishing boats in a protected refuge.
- Vaquita numbers have been decimated in the past decade as a result of gillnet fishing for another critically endgangered species, the totoaba, a fish whose swim bladder can fetch more than $20,000 per kilogram ($9,000 per pound) in Asian markets.
- Local fishing organizations in the region say that the government has stopped compensating them after a gillnet ban, aimed at protecting the vaquita from extinction, went into effect in 2015.
Commitments worth $63 billion pledged for ocean protection
- The sixth annual Our Ocean conference took place in Oslo, Norway, on Oct. 23 and 24.
- Governments, businesses, organizations and research institutions made 370 commitments toward improving marine health and productivity that were worth more than $63 billion.
- The commitments, a considerable boost from the $10 billion committed last year, reflect a new level of urgency around ocean protection as its role in mitigating climate change becomes ever clearer.
- Focus areas of the conference included building the sustainability of the global fishing industry and reducing plastic pollution.
In Indonesia, a court victory for Bali’s ban on single-use plastics
- Indonesia’s top court has rejected a challenge to a ban on single-use plastics on the island of Bali.
- The ban was proposed last December and was subsequently challenged by plastic-recycling industry, which argued it would harm the livelihoods of manufacturers, recyclers, and trash pickers.
- The ruling potentially paves the way for other local governments around Indonesia to impose their own bans on plastic.
- The country is the number two source of the plastic waste that ends up in the oceans, behind only China, and has set itself the target of reducing that waste output by 70 percent by 2025.
Twice as many fishing vessels now, but it’s harder to catch fish
- The global fishing fleet has more than doubled from about 1.7 million boats harvesting fish in 1950 to 3.7 million fishing vessels in 2015.
- More fishing vessels have become motorized as well: while only 20 percent of the world’s fishing vessels were powered by motors in 1950, this number rose to 68 percent in 2015.
- The growing fishing fleet is, however, catching less seafood for the same effort.
- There are geographic variations: while Asia’s fishing fleet has dramatically increased over the past decades, catching fewer fish for the same effort, fleet sizes in North America and Western Europe shrank slightly, accompanied by an increase in fish catch per unit effort.
Brazil green-lights oil prospecting near important marine park
- In April, the president of Brazil’s environmental regulatory agency authorized the auction of seven offshore oil blocks located in highly sensitive marine regions.
- In doing so, he ignored technical recommendations made by his own environmental team — a first in the team’s 11-year history.
- The environmental team argued that if there were to be an oil spill, the contamination could affect the coasts of two Brazilian states, including the Abrolhos Marine National Park, which is considered the most biodiverse area in the South Atlantic.
- More broadly, the Brazilian Congress is also considering a bill that would profoundly change the way environmental authorizations are issued, abolishing the need for licenses for most farming and infrastructure activities and accelerating the procedure for other ventures.
The health of penguin chicks points scientists to changes in the ocean
- A recent closure of commercial fishing around South Africa’s Robben Island gave scientists the chance to understand how fluctuations in prey fish populations affect endangered African penguins (Spheniscus demersus) absent pressure from humans.
- The researchers found that the more fish were available, the better the condition of the penguin chicks that rely on their parents for food.
- This link between prey abundance in the sea and the condition of penguin chicks on land could serve as an indicator of changes in the ecosystem.
’Unprecedented’ loss of biodiversity threatens humanity, report finds
- The U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services released a summary of far-reaching research on the threats to biodiversity on May 6.
- The findings are dire, indicating that around 1 million species of plants and animals face extinction.
- The full 1,500-page report, to be released later this year, raises concerns about the impacts of collapsing biodiversity on human well-being.
Weak governance undermines South America’s ocean ecosystems
- Illegal fishing, overfishing and pollution are common problems in the waters of South America.
- For instance, Ecuadoran small-scale fishing captures at least 250,000 sharks every year, most of them apparently illegally, and 62 percent of Chile’s fisheries are overexploited or depleted.
- But the overarching problem, the one that enables the rest, is weak governance, according to experts.
- This article encapsulates a series of stories by Mongabay Latam examining the state of the sea in Chile, Peru, Colombia and Ecuador.
Bird flu in Namibia’s penguins wanes, after killing nearly 500
- More than 450 African penguins, an IUCN-listed endangered animal, have died in an outbreak of bird flu on three islands off the coast of Namibia.
- The virus, H5N8, is thought to have been introduced to the colonies, which hold 96 percent of Namibia’s penguins, by another bird traveling from South Africa, where a similar outbreak occurred in 2018.
- The disease appears to be abating, and researchers are hopeful that the country’s penguins will recover.
- However, they continue to face threats from food shortages caused by overfishing and climate change.
Swelling amount of plastic in the ocean confirmed by new study
- A new study used log books from 60 years of plankton research to document the increase in the amount of plastic in the ocean.
- The study’s authors tabulated the entanglements of the continuous plankton recorder, a sampling device that’s towed behind ships, revealing a significant increase in plastic in the ocean since the 1990s.
- Scientists have long suspected such a trend but have been unable to demonstrate it with data until now.
Scientists urge overhaul of the world’s parks to protect biodiversity
- A team of scientists argues that we should evaluate the effectiveness of protected areas based on the outcomes for biodiversity, not simple the area of land or ocean they protect.
- In a paper published April 11 in the journal Science, they outline the weaknesses of Aichi Biodiversity Target 11, which set goals of protecting 17 percent of the earth’s surface and 10 percent of its oceans by 2020.
- They propose monitoring the outcomes of protected areas that measure changes in biodiversity in comparison to agreed-upon “reference” levels and then using those figures to determine how well they are performing.
Indonesia oil slicks highlight weak enforcement against bilge dumping
- An environmental monitoring group has published reports saying that two ships have been pumping their waste oil out to sea, in a process known as bilge dumping, off the coast of Sumatra.
- The findings are based on a combination of satellite imagery of the slicks, which extend a total of 135 kilometers (84 miles), and tracking data from the ships.
- Activists say these findings highlight just how common bilge dumping is in Indonesian waters, and the lack of enforcement against the practice.
- Officials had not commented on the matter as of the time this story was published.
