Pacific island nations launch plan for world’s first Indigenous-led ocean reserve
The governments of the Solomon Islands and Vanuatu have announced their commitment to create a massive multinational Melanesian Ocean Reserve. If implemented as envisioned, the reserve would become the world’s first Indigenous-led ocean reserve, covering an area nearly as big as the Amazon Rainforest. Speaking at the U.N. Ocean Conference underway in Nice, France, representatives […]
French Polynesia creates world’s largest marine protected area
French Polynesia has announced the creation of the world’s largest marine protected area. Speaking on the first day of the United Nations Ocean Conference in France, French Polynesian President Moetai Brotherson said the MPA will cover the territory’s entire exclusive economic zone (EEZ), or 4.8 million square kilometers (roughly 1.9 million square miles). “We have […]
Stars & lighthouses: Marine conservation that blends Pacific Islander wisdom and Western knowledge (commentary)
- The U.N. Ocean Conference this week is tackling a range of issues, such as how to conserve and sustainably use the oceans and marine resources: a new op-ed argues that the strength of Indigenous islander conservation practices lies in their flexibility and adaptability, while Western conservation efforts bring clear, formal, and intentional goals — and that blending the two can return inspiring results.
- “Conservation is not just about the number of lighthouses we build — about visible policies and formal designations — but we must also name and recognize the stars that have guided us all along; the quiet, steadfast traditions that have protected our oceans for thousands of years,” the author writes.

Samoa’s new marine spatial plan protects 30% of the country’s ocean
- The Samoan government announced June 3 that it has enacted a law establishing a marine spatial plan to sustainably manage 100% of its ocean by 2030.
- The country has also created nine new marine protected areas that cover 30% of its ocean.
- Fishing is prohibited in the new protected areas, which include a migration route for humpback whales.
- The plan became law on May 1.
Marine artificial upwelling, problematic climate solution slow to advance
- Artificial upwelling is a form of geoengineering that aims to use pipes and pumps to channel cool, nutrient-rich water from the deep ocean to the surface. In doing so, it could fertilize surface waters, prompting the growth of plankton, which can then absorb and store large amounts of atmospheric carbon.
- Long considered a potential marine carbon dioxide removal (CDR) method, artificial upwelling has more recently been coupled with seaweed farming to potentially soak up even more atmospheric CO2.
- But technological challenges have plagued open-water upwelling experiments, while environmentalists worry that large-scale use could ultimately prove ineffective and ecologically harmful.
- Experts state that though upwelling could prove a viable solution to improve fisheries and protect coral reefs from marine heat waves, more research is needed. Considering the rapid current pace of climate change, it’s debatable as to whether implementation at scale could come in time to stave off dangerous warming.
Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
- Drifting fish aggregating devices (dFADs) are floating rafts with underwater netting used by fishing vessels to attract tuna.
- A recent study estimated that between 2007 and 2021, 1.41 million dFADs drifted through 37% of the world’s oceans, stranding in 104 maritime jurisdictions and often polluting sensitive marine habitats.
- Strandings were most frequent in the Indian and Pacific oceans, with the Seychelles, Somalia and French Polynesia accounting for 43% of cases; ecosystem damage and cleanup costs fall on local communities.
The blobby little sea squirt that stowed away across the Pacific to California
- In 2023, scientists found a nonnative species of marine invertebrate in a private marina near Los Angeles, California.
- The arrival of this new member of California’s marine fauna highlights the massive, largely uncontrolled movement of marine species via ships that travel the world.
- Concerned about potential ecological and economic impacts, the state of California has tried to curb the movement of nonnative marine species through regulations of large ships and commercial ports, but the regulations don’t apply to smaller vessels.
- Beginning in 2025, California will have to comply with less-stringent federal biofouling and ballast water regulations.
Brazil & China move ahead on 3,000-km railway crossing the Amazon
Plans to build a railway that would slice South America from east to west, crossing part of the Amazon Rainforest, are advancing with Chinese funding, according to a recent announcement by the Brazilian government. Brazil President Luiz Inácio Lula da Silva, along with ministers and Chinese officials, including President Xi Jinping, met in Beijing on […]
Our responsibility for cetacean conservation grows with proof of their intelligence (commentary)
- In the search for other intelligent life in our galaxy, we must look to the oceans before we turn to the stars, states the writer of a new commentary.
- In recent years, cetacean researchers have shown that whales, dolphins and porpoises live socially complex lives that require elaborate communication systems, and possibly even language.
- “If people can understand what they have in common with an animal that is seemingly so alien on the surface, it would allow for a greater extension of empathy,” and therefore greater conservation efforts, the writer argues.

Under Trump, US retreats from global fisheries and oceans leadership
- The United States has long been an international leader in fisheries and oceans science, with influence at international fora that it has sometimes wielded to support conservation measures and crackdowns on illegal fishing.
- However, U.S. influence at fisheries and oceans fora appear to be waning during the second Trump administration, which could compromise fisheries health and marine conservation, experts say.
- The administration, which took office Jan. 20, has begun to institute a program of budget and staff cuts at U.S. departments and agencies that work on fisheries and oceans governance, while turning away from or undercutting multilateral organizations.
Sweeping cuts and deregulation imperil U.S. fisheries, experts warn
- The United States has long had one of the best systems of fisheries management in the world, supporting 2.3 million jobs and a relatively high number of healthy fish populations.
- The Trump administration is enacting sharp cuts to the budget, staff and facilities of the agency that manages U.S. fisheries, the National Oceanic and Atmospheric Administration (NOAA), and on April 17 ordered widespread deregulation of fisheries.
- The administration says the changes are necessary to reduce government waste and fraud, save taxpayer money, create jobs and enhance profitability, but experts and former NOAA employees told Mongabay these moves have been poorly planned and will be “devastating” for U.S. fisheries.
- The staff cuts, regulatory changes and facilities downsizing are not easy for the public to track, raising questions about the transparency of the Trump administration’s moves.
‘Substantial’ transshipment reforms adopted at North Pacific fisheries summit
- The annual meeting of the North Pacific Fisheries Commission (NPFC), a multilateral body that manages most non-tuna fisheries in the region’s international waters, was held March 24-27 in Osaka, Japan.
- In a bid to deter illegal fishing, the NPFC’s nine members agreed to require independent observers on ships that transfer fish at sea.
- The parties agreed to study the impact of bottom fishing on ocean habitats and to protect two small areas on one seamount. They also increased transparency in the NPFC compliance process and reduced the total allowable catch for two key pelagic species.
Panama conducts large illegal fishing bust in protected Pacific waters
- Panamanian authorities seized six longliner vessels on Jan. 20 for fishing illegally in protected waters. They also opened an investigation into an additional 10 vessels that surveillance data showed had apparently been fishing in the area but left by the time authorities arrived.
- The seizures took place in the Cordillera de Coiba, a marine protected area that’s part of the Eastern Tropical Pacific Marine Corridor, which connects several MPAs in four countries. It was the largest illegal fishing bust in the history of Panama’s MPAs.
- The vessels, whose activity is still under investigation, were Panamanian-flagged, meaning they were registered in the country, but the identity and nationality of the owners isn’t clear.
- The surveillance work in the case was done in part through Skylight, an AI-powered fisheries intelligence platform, and was supported by a group of fisheries monitoring nonprofits.
‘Fatal Watch’: Interview with documentary makers on fisheries observer deaths
- A new documentary, “Fatal Watch,” shows the dangers of work as a fisheries observer, a job that involves collecting scientific data aboard industrial fishing vessels and documenting compliance with conservation and other rules.
- The film focuses on four cases in which fisheries observers died or disappeared on the job during the last decade.
- “Fatal Watch” also casts a critical eye on the fishing industry as a whole, touching on management and transparency issues that the filmmakers see as intertwined with the observer safety problem.
- The film will premiere in California on March 21 at the Sonoma International Film Festival and play in Washington, D.C., on March 24 at the DC Environmental Film Festival, where Mongabay is a media partner.
Seal ‘oceanographers’ reveal fish abundance in Pacific Ocean’s twilight zone
- The open ocean’s twilight zone, a vast deep ecosystem rich in fish biomass, is poorly understood because it is expensive and challenging for humans to reach its depths 200–1000 meters (660–3,280 feet) below the surface.
- A new study used northern elephant seals (Mirounga angustirostris) — marine predators that forage in the twilight zone — to help understand fish abundance deep down, both five decades into the past and two years into the future.
- The findings illustrate how apex marine predators, such as elephant seals, can serve as sentinels in understanding how fish abundance cascades through marine food webs.
- Given increased interest in fishing in the twilight zone and the unfolding effects of climate change, seals and other deep-diving marine predators could help keep an eye on changes in the oceans’ depths.
500,000 barrels of DDT in the sea: Interview with documentary directors on California coast crisis
- “Out of Plain Sight,” directed by journalist Rosanna Xia and filmmaker Daniel Straub, documents the legacy of mass amounts of DDT waste dumped off the California coast decades ago, with environmental consequences continuing today.
- The documentary features journalism as a main character, following Xia’s real-time investigation and highlighting both the process of science and storytelling through immersive cinematography and sound design.
- The film raises urgent questions about today’s “forever chemicals” and our relationship with the ocean environment.
- The film will be screened in Washington, D.C., on March 29 at the 2025 DC Environmental Film Festival, where Mongabay is a media partner.
Initiative sets sights on rewilding three New Zealand islands
Three New Zealand islands will join an international initiative to remove invasive species and restore native wildlife. With the addition of Maukahuka (Auckland) Island, Rakiura (Stewart) Island and Chatham Island, the Island-Ocean Connection Challenge (IOCC) will have 20 ongoing projects aimed at restoring and rewilding 40 globally significant island-ocean ecosystems by 2030. “New Zealand’s three […]
Study finds signs of tuna abundance outside marine protected areas
- Experts debate the degree to which marine protected areas (MPAs) that are closed to industrial fishing boost fish population abundance or fishing success outside their borders.
- A recent study indicates that large-scale no-fishing MPAs do provide “spillover” benefits: It showed purse seiner vessels caught more tuna per unit of fishing effort in the 100 nautical miles (185 kilometers) surrounding large MPAs than they would have if the MPAs did not exist.
- Such findings could strengthen the case for establishing large MPAs, which could be on the table once international agreements, including the High Seas Treaty, are rolled out in coming years.
- Some fisheries scientists argue that MPAs are not a good method of fisheries management; one critiqued the recent study.
New Zealand blocks tighter trawling rules at South Pacific fisheries meeting
- The South Pacific Regional Fisheries Management Organisation (SPRFMO), a multilateral body that regulates fishing in the vast waters of the South Pacific Ocean, held its annual meeting Feb. 17-21 in Santiago, Chile.
- At the meeting, Aotearoa New Zealand blocked an effort to implement a rule that would reduce bottom trawling, a fishing practice that disrupts the seabed, in areas occupied by vulnerable marine ecosystems.
- Conservationists lambasted New Zealand’s move, while a New Zealand official defended the country’s approach.
- In other meeting news, the parties raised the fishing quota for jack mackerel above scientifically advised limits and, at the same time, moved forward toward adopting a harvest strategy for the stock that could prevent such abrupt quota hikes in the future.
Funerary practices in Fiji protect marine areas while honoring the deceased
- Indigenous (iTaukei) people across Fiji have historically protected their freshwater and marine areas in memory of chiefs and community members who have passed away. These are called aquatic funerary protected areas (FPAs).
- Researchers published a study to shine a light on this sustainable resource management practice, which they say could present a community marine conservation solution in the region but is largely absent from scientific literature and rarely implemented as a strategy.
- FPAs differ in size and practice but can stretch from shoreline to fringing reefs and tend to ban fishing and harvesting of many species for 100 nights after they are declared.
- From 1960 to 2019, communities established a total of 188 FPAs where 44% of FPAs were protected for 100 nights, and 47% protected all resources and associated ecosystems form fishing and harvesting.
Wisdom, the world’s oldest known bird at 74, has a new chick
Wisdom, the world’s oldest known wild bird, made headlines recently for laying an egg with a new partner, her first egg in four years. The egg has now hatched, and Wisdom, a Laysan albatross (Phoebastria immutabilis), or mōlī in Hawaiian, was spotted caring for her chick, the U.S. Fish and Wildlife Service (USFWS) Pacific region […]
Over half of Pacific atoll forests are coconut palm plantations — Study
What’s new: More than half of the tree cover in Pacific atolls is largely composed of “abandoned and overgrown” colonial-era coconut palm plantations, reveal satellite images in a study published in December 2024. What the study says: While coconut palm is an integral part of the cultures and economy of Pacific Island communities, colonial powers […]
Marshall Islands protects ‘pristine’ Pacific corals with first marine sanctuary
The Marshall Islands government has announced it will protect an area of the Pacific Ocean described as one of the most “remote, pristine” marine ecosystems on Earth. The 48,000-square-kilometer (18,500-square-mile) marine sanctuary covers two of the country’s northernmost uninhabited atolls, Bikar and Bokak, and the surrounding deep sea, and it is the first federal marine […]
In Panama, major port construction begins at key mangrove site
- The Puerto Barú project, located outside the town of David in the Pacific province of Chiriquí, will be a new industrial port on Panama’s west coast, where channels and lagoons support mangroves, breeding grounds and nurseries for a variety of marine species.
- The project requires dredging a riverbed and increasing maritime traffic of cargo ships, cruise ships and yachts.
- More than 50 conservation groups have organized a “No to Puerto Barú” campaign, but an initial injunction to stop construction was shot down in court.
Global ocean temperatures set new record in 2024
- Average temperatures across the world’s oceans reached an all-time high in 2024, according to a multi-team study published Jan. 10.
- The temperatures surpassed even those of 2023, which themselves represented a marked uptick over any previous years on record.
- Each of the two main metrics for ocean temperature hit a record high in 2024, while a commonly cited overall metric that accounts for both land and sea temperatures also reached a new high.
- The findings fit with a decades-long trend of ocean heating. The long-term rise is both a result of climate change and a cause of climate change effects like sea-level rise and increased likelihood of extreme weather.
Pacific’s ‘Blob’ heat wave killed millions more seabirds than thought: Study
In 2016, scientists became aware of a die-off of common murres, seabirds resembling flying penguins, that were found washed ashore from Alaska to California. A 2020 study estimated, based on an extrapolation from carcasses found on beaches, that roughly 1 million murres may have died, calling it “unprecedented and astonishing,” even “biblical.” However, a new […]
Research vessel E/V Nautilus spots multiple nautiluses for the first time
The crew of the research vessel E/V Nautilus erupted in excited chatter as they watched live video from a remotely operated vehicle traversing the German Channel in the Pacific island state of Palau. “It’s finally happened!” someone could be heard saying as the camera on board the ROV Hercules zoomed in to reveal a lone […]
First-of-its-kind crew welfare measure adopted at Pacific fisheries summit
- The organization that sets fishing rules for a swath of the Pacific Ocean covering nearly 20% of Earth’s surface and supplying half the world’s tuna catch held its annual meeting in Fiji from Nov. 28 to Dec. 3.
- Parties to the Western and Central Pacific Fisheries Commission (WCPFC) adopted a landmark crew welfare measure — the first binding labor rights measure adopted by any of the world’s 17 regional fisheries management organizations.
- The parties, 25 countries plus the European Union, also adopted a voluntary measure to implement electronic monitoring of catches.
- However, they didn’t adopt a proposal to curb potentially dodgy ship-to-ship transfers known as transshipments, or substantive new protections for sharks and seabirds, as NGO observers had hoped.
Teamwork makes the dream work for orcas hunting world’s biggest shark
Orcas, or killer whales, are the apex predator in the ocean when they work together. A new study documents how a pod of orcas is able to hunt and kill the largest fish in the world, the whale shark (Rhincodon typus), which can be twice the size of an individual orca (Orcinus orca), though the […]
In a Noah’s Ark move, PNG migrants bring thousands of trees to safer ground
- Facing sea level rise and food insecurity, 17 families from the Carteret Islands have relocated to nearby Bougainville, bringing hundreds of specimens of trees and plants, representing dozens of species, across a small stretch of ocean.
- They’ve planted more than 175,000 plants, breathing life into a forest on new lands donated by the Catholic Church.
- This “green migration” is helping them preserve their lifestyle and identity, sources say, echoing the journey of early Polynesian settlers who carried “canoe plants” as they sailed and settled across the Pacific.
- Scientists say green migrations could become part of climate relocation planning, but there also needs to be careful consideration of whether species can be moved and become unsustainably invasive.
World’s largest known coral — visible from space — found in Solomon Islands
Scientists aboard a National Geographic research vessel recently discovered the largest known coral in the world. The massive coral, which is 34 meters wide (112 feet) and 32 meters (105 feet) long, is visible from space. It’s a coral of the species Pavona clavus, which typically grows to just 2-3 meters (6.5 to 9.8 feet) […]
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.
Largest dam removal ever, driven by Tribes, kicks off Klamath River recovery
- The largest dam-removal project in history was completed in October, freeing 676 kilometers (420 miles) of the Klamath River and its tributaries in California and Oregon.
- The project involved removing four dams, built between 1918 and 1964 to provide electricity. They had devastating effects on salmon populations and tribal communities, leading to a decades-long, tribe-led movement for their removal.
- The $450 million project involved complex engineering to remove the dams and, now, to restore the river ecosystem, including replanting native vegetation and reshaping the river channel, incorporating tribal knowledge to improve habitats for salmon and other species.
- The first chinook salmon in more than 60 years are already spawning above the former Iron Gate dam and a fall-run Chinook salmon was identified in Oregon for the first time in more than 100 years. Experts expect coho salmon populations to recover in six to 12 years and Chinook salmon in 15 to 20 years in what was once the third-largest salmon producing river in the contiguous U.S.
U.S. government and Indigenous tribes to co-manage newest marine sanctuary
In advance of Indigenous Peoples’ Day in the U.S., the federal government announced a new national marine sanctuary off the coast of California that will be co-managed with tribes and Indigenous groups in the area. The Chumash Heritage National Marine Sactuary will be the third-largest federally protected stretch of water, encompassing more than 11,600 square […]
In the Pacific depths, an underwater mountain hosts a bonanza of new species
- Scientists discovered a new underwater mountain and more than 100 potentially new-to-science species during recent expeditions in the Southeast Pacific, including rare creatures like flying spaghetti monsters and Casper octopuses.
- The newly found seamount, located about 1,450 km (900 mi) off Chile’s coast, rises 3,100 meters (nearly 2 miles) from the seafloor and hosts thriving deep-sea ecosystems with ancient corals and glass sponges.
- These findings highlight the rich biodiversity of the high seas and come at a crucial time as the U.N. finalizes the high seas treaty to protect international waters.
- While the treaty sets rules for marine protected areas, challenges remain in its implementation, including formal adoption and ratification by at least 60 countries.
Fishing in a fog: Ship noise hampers orcas’ hunting success
Underwater noise from ships is making it tough for killer whales, or orcas, to find and catch their favorite fish, a recent study has found. Orcas (Orcinus orca) rely heavily on sound to hunt. They emit ultrasonic echolocation clicks that bounce off objects. By listening for the echoes of these clicks, the orcas can identify […]
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.
Oxygen made by metal redefines scientific understanding
Potato-sized lumps of metal on the seafloor are generating oxygen, a new study has found. Scientists previously believed that oxygen was strictly formed as a byproduct of photosynthesizing plants. However, these oxygen-producing bits of metal, called polymetallic nodules, were found in the deep ocean, far beyond the reach of the sun’s rays. Researchers made the […]
French Polynesians revive traditional rāhui to protect fish — and livelihoods
- In French Polynesia, fishing is of paramount importance. Many residents depend on fishing to feed their families and make a living.
- Confronted with a decline in fish stocks, communities across the country are reviving a traditional method of managing natural resources called rāhui.
- This bottom-up solution, managed by local communities with help from scientists and the government, although imperfect, appears to demonstrate some degree of effectiveness.
- The island of Tahiti currently counts 13 rāhuis, and more communities are establishing them as a way to fight poverty, sustain fishers’ incomes and regain their culture.
Otter-preneurs: Female sea otters lead the way in tool use for survival
- In Monterey Bay, California, southern sea otters face food scarcity as their preferred prey, urchins and abalone, have declined due to climate change, overfishing and other environmental factors.
- To adapt, some sea otters, particularly females, use tools like rocks, shells and even discarded glass bottles to crack open harder-shelled alternative prey like snails, clams and mussels.
- A study of 196 tagged sea otters found that frequent tool users, especially females, could consume prey up to 35% harder than non-tool users and had significantly less tooth damage.
- The findings highlight the importance of behavioral flexibility in the face of ecological challenges and underscore the need to protect the threatened southern sea otter population, which plays a crucial role in maintaining the balance of coastal ecosystems.
18 years on, how are sharks faring in French Polynesia’s shark sanctuary?
- While sharks are feared and threatened in many parts of the world, French Polynesia decided to protect them two decades ago by declaring its entire exclusive economic zone a massive sanctuary for sharks and rays.
- The move aligns with traditional beliefs that hold sharks as sacred animals that represent gods and the link between past and present.
- New citizen-science data offer some evidence the sanctuary is working to protect sharks, but more research is needed to confirm it.
- Sharks still face threats there from accidental bycatch and illegal fishing, and some conflicts with local fishers have emerged.
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.
It will take 880 years to achieve UN ocean conservation goals, at this rate (commentary)
- Indigenous conservationist Angelo Villagomez will speak at the Our Ocean conference, one of the largest and highest profile conferences of its kind, this week in Athens, Greece.
- He plans to say that ocean conservation has lost momentum toward protecting 30% of the ocean by 2030 and that a lot more needs to be done to address the human dimensions of conservation, including guaranteeing access rights, equity, and justice.
- “At this rate, raising the area of global ocean protection from 8% to 30% will take an additional 880 years,” he argues in a new op-ed.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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.
‘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.
Salmon and other migratory fish play crucial role in delivering nutrients
- Pacific salmon can play a key role in transporting nutrients from marine to freshwater and terrestrial ecosystems.
- In the past, Pacific salmon and other anadromous fish that spawn in freshwater and spend part of their life in the ocean likely played a much larger role in global nutrient cycles, scientists find.
- But today, many populations of Pacific salmon and other anadromous fish are under pressure from habitat loss, overfishing, climate change, dams and other pressures that have greatly reduced their numbers, weight and ability to migrate freely.
- Population declines could further curtail their role in global nutrient transport in future, with increasing consequences, especially for nutrient-poor ecosystems that have relied in the past on migratory fish for significant nutrient additions.
Photos: Top species discoveries from 2023
- Scientists described a slew of new species this past year, including an electric blue tarantula, two pygmy squid, a silent frog, and some thumb-sized chameleons.
- Experts estimate less than 20% of Earth’s species have been documented by Western science.
- Although a species may be new to science, it may already be well known to local and Indigenous people and have a common name.
- Many new species of plants, fungi, and animals are assessed as Vulnerable or Critically Endangered with extinction as soon as they are found, and many species may go extinct before they are named, experts say.
Marine conservation technology hub rises from old L.A. wharf (analysis)
- In 2014, the Port of Los Angeles gave a 50-year lease to an aging wharf called City Dock No. 1 to a project called AltaSea.
- AltaSea is a non-profit project founded in 2014 that in less than 10 years has become a leading ‘blue economy’ research hub focused on renewable ocean energy, sustainable aquaculture and other blue technologies.
- Hub tenants include marine renewable energy startups, sustainable aquaculture projects, a marine seed bank, a research effort aimed at decarbonizing oceanic shipping, and other projects.

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.
Galápagos waters yield massive deepwater corals in latest biodiversity find
- Researchers have found two new deepwater coral reefs, including one that spans more than 800 meters, or half a mile long, in the waters around the Galápagos Islands.
- They were discovered through the process of mapping the seafloor in Galápagos Marine Reserve with laser scanning technology.
- The reefs displayed a diversity of stony coral species and other organisms such as crustaceans, sharks and skates.
- The discovery of these two reefs occurred six months after the first discovery of deepwater reefs in the waters of the Galápagos Islands.
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.
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.
Hope, but no free pass, as Pacific corals show tolerance to warming oceans
- New research suggests that coral reefs in the Pacific islands of Palau are becoming increasingly tolerant to thermal stress brought on by climate change.
- The study found that Palau’s coral reefs appeared to suffer less bleaching over three successive marine heat waves in 1998, 2010 and 2017.
- While the findings provide some hope for coral reefs, one expert says the study has some limitations in providing a clear picture of how corals respond to different heat events.
- Scientists also say that reducing carbon emissions is essential to safeguard coral reefs — and to secure the planet’s future.
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.
To protect the oceans, we must map them (commentary)
- About 80% of our oceans remain “unmapped, unobserved, and unexplored,” according to NOAA.
- Technologies like un-crewed marine drones, high-resolution satellites, and remote operating vehicles are now being paired with modern digital mapping techniques to reveal critical new insights about the oceans.
- “Considering we’ve barely mapped a quarter of [the oceans] so far, imagine what we could know, what we could prepare for, if every inch was mapped,” a new op-ed suggests.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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.
Australia bushfires may have caused global climate phenomenon La Niña: Study
- The 2019-2020 Australian bushfires threw up so much ash into the atmosphere that it resulted in a cooling of the southern Pacific and hence a La Niña climate phenomenon, a new study says.
- Volcanic eruptions that send vast ash plumes into the atmosphere are thought to trigger La Niña events, but this is the first time a fire has been recorded as doing so.
- La Niña can produce ruinous weather conditions in contrasting ways, from additional hurricanes in North America and droughts in the Horn of Africa, to crop failures in South America.
- The study’s findings call into question the assumption in current climate models that biomass emissions — including from bushfires — will decrease over time.
Hawaiian communities restore Indigenous conservation, from mountains to sea
- In Hawai’i, an Indigenous stewardship and conservation system known as ahupua’a is slowly being revived on a mountain-to-sea scale in partnership with U.S. government agencies.
- Three Indigenous communities that have successfully reintroduced the ahupua’a system are seeing some conservation successes, such as a 310% increase in the biomass of surgeonfish and an increase in the Bluespine unicornfish (Naso unicornis) population.
- The inclusion of Indigenous Hawaiian conservation, social and spiritual values, like Aloha kekahi i kekahi, have been key to building these conservation areas and forming better working relations with the government.
