Observations off Ecuador document plastic debris at roughly 3,900 metres. The finding extends the evidence beyond beaches, while leaving transport routes and regional totals uncertain.

A global study asks whether newly flooded coastal land could become suitable habitat for marine species already established outside their native ranges.

A Brazilian sediment study shows why chemical measurements and biological tests answer different questions when dredged material is considered for disposal on land.

IWC70 has adopted a vessel-strike resolution. Its discussions on underwater noise also show why whale conservation needs evidence about how vessels use the sea.

Deep learning is helping researchers analyse decades of blue- and fin-whale recordings, with human review and explicit uncertainty.

A Thai marine protected area assessment shows why legal designation must be followed by staff, funding and evidence of outcomes.

A Jamaican study found most measured mangrove carbon below ground. Its lesson for conservation reaches beyond the visible forest canopy.

A Bay of Biscay modelling study explores how seasonal protection could complement permanent marine protected areas.

A Colombian fisheries study shows why understanding livelihoods and local knowledge should be part of conservation planning from the start.

A reanalysis of Ecuadorian Pacific samples shows why a pollution trend depends on the question, sampling design and statistical method.

NOAA is testing a drone-deployed suction-cup tag to study humpback hearing. The early results are promising, but a direct hearing measurement remains the goal.

New drone research shows that collision risk depends not only on where whales and vessels meet. What a whale is doing at that moment can substantially affect its vulnerability. Collisions with vessels are a serious threat to whales around the world. Understanding that risk has traditionally focused on a relatively straightforward question: where do shipping routes and whale habitats overlap? New research suggests that another question matters too: What are the whales doing wh

Local whale-watching guides are reporting unusually few humpback whale sightings in Golfo Dulce this season. At the same time, the Eastern Tropical Pacific is experiencing exceptional ocean warming. The connection is not yet proven, but it deserves close attention. August is normally one of the most reliable months for encountering humpback whales in Golfo Dulce. In 2026, something appears different. Experienced local guides have reported that humpbacks have been considerably

New research suggests that climate conditions may be changing when humpback whales arrive in Costa Rican waters. Golfo Dulce is extraordinary for many reasons. One of the most remarkable is that humpback whales migrating from both the Northern and Southern Hemispheres use Costa Rica's Pacific waters. For years, whale watching has generally been described in terms of two relatively predictable seasons. New research suggests that reality may be becoming more complicated. Scient

New research shows that protecting vegetation along rivers may be one of the most effective ways to protect the coastal waters of Golfo Dulce. When we think about marine conservation, we tend to look toward the ocean. But some of the most important decisions affecting Golfo Dulce are made kilometres inland. A major new study has analysed land use and coastal water turbidity around 119 river mouths and 64 watersheds in Golfo Dulce. The result is striking. Natural vegetation wi

August 17, 2026 Today we can share an important step in the development of #SaveGolfoDulce. TerraVita Solutions e.V., the non-profit organization behind #SaveGolfoDulce, has officially been recognized by the German tax authorities as serving charitable purposes. It may sound like an administrative milestone. For us, it means much more. From an idea to a lasting organization #SaveGolfoDulce began with a simple conviction. The Golfo Dulce is too exceptional to take for granted.

Every year, one of the world’s great wildlife migrations reaches the warm waters of southern Costa Rica. After travelling thousands of kilometres, humpback whales from the Southern Hemisphere arrive along the Pacific coast of Central America to reproduce, give birth and care for their young. And the Golfo Dulce is one of the places that matters. A nursery surrounded by rainforest The geography of the Golfo Dulce makes it extraordinary. Deep water extends far into a sheltered

When people think of the Golfo Dulce, they often picture rainforest-covered hills, dolphins, whales and calm tropical waters. But some of the most important ecosystems are found where land and sea meet. Mangroves are one of them. Around the Golfo Dulce, mangrove forests form a living connection between rivers, rainforest and ocean. They provide habitat for wildlife, stabilize coastlines and create sheltered areas used by fish and many other marine species during critical stag

The future of Golfo Dulce depends on how we treat its forests, rivers, mangroves and marine habitats today. Golfo Dulce is connected by water, forest and life. Rivers bring freshwater and nutrients into the gulf. Mangroves protect coastlines and serve as nurseries for fish. Rainforests stabilize the land and provide habitat for countless species. The ocean links all of it together. But this balance is vulnerable. Pollution, careless development, illegal activity and weak prot

Deep tropical waters, rainforest-covered shores and rare marine life make Golfo Dulce one of Costa Rica’s most extraordinary natural places. Golfo Dulce is often described as one of only four tropical fjords in the world. Whether you call it a tropical fjord, a fjord-like gulf or a rare marine basin, one thing is clear: this place is exceptional. Located in southern Costa Rica, Golfo Dulce combines deep sheltered waters, rainforest-covered coastlines, mangroves, rivers and ri
