The #BBNJ Agreement could help fix long-standing weaknesses in high seas fisheries management.
By coordinating fragmented efforts and filling governance gaps, authors argue it may strengthen regional fisheries bodies without undermining their mandates.
Tropical cyclones are travelling over rapidly warming waters, and their ability to cool the ocean surface is weaker than once thought.
This mismatch means storms may become stronger than climate models currently predict, increasing future risks. https://www.nature.com/articles/s41561-025-01900-3
A fundamental shift occurred around 2009: the Arctic has flipped from being limited by light to being limited by nitrogen. As sea ice retreats, increased plant growth on shallow Arctic shelves is driving far greater loss of nitrate from the water, reshaping the base of the food web.
📢 The third World Ocean Assessment documents a deepening crisis, as climate change, pollution, overfishing and biodiversity loss put ocean systems under severe strain. Its findings demand urgent action, through stronger multilateral cooperation, greater ambition & decisions grounded in science.
🌊 On #WorldOceanDay, we celebrate the incredible ocean processes that regulate our climate and make life on Earth possible.
From circulating currents to microscopic plankton—and even 🐟 fish—our ocean plays a huge role in capturing and storing carbon. #BlueCarbon #OceanClimate
🆕 1,121 new marine species discovered!
From a chimaera, to the "Glass Castle" Worm and Carnivorous "Ping-Pong Ball" Sponge, here are the new species discovered on @oceancensus.bsky.social -led expeditions:

Climate-driven changes in thermal habitat play a stronger role in pushing humpback whales into dangerous fishing zones. 🐋
Stopping #IUUFishing is an essential tool to restore ocean health and combat the global climate crisis. #WorldEnvironmentDay #FightIUUFishing
In response to #ClimateChange, seabirds are changing in geographic range size rather than body mass, and dispersing longer distances.
4 specific species face a severe, immediate risk of extinction under future warming scenarios.

#Antarctica experienced an unprecedented coastal disturbance event in 2025.
Record-low seasonal sea ice allowed exceptional iceberg movement, producing the highest seabed scouring ever recorded near the West Antarctic Peninsula, with potential major long-term biodiversity impacts.

Over decades, the management of the high sea fisheries have been frustrated by a series of enduring issues such as the “free-rider” and non-compliance…

Scientists say they’ve found more than 1,100 new marine species over the last year, emphasizing how unexplored the ocean really is.
Global drifter data reveal that tropical cyclone-induced sea surface cooling in storm-affected areas is far weaker than indicated by estimates from microwave satellites and state-of-the-art climate mo...

The Arctic Ocean may have crossed a dangerous tipping point. Scientists say the rapid disappearance of sea ice is triggering a hidden chemical shift that is stripping the ocean of nitrate — a nutrient...

Antarctica is an extreme region in many ways and long term marine ice monitoring shows 2025 was the most of those extremes. Seasonal sea ice duration was observed daily at Rothera Research Station, A...

Off the U.S. West Coast, humpback whales are increasingly entangling in fishing gear, posing a dire threat to their survival. New research from Jarrod Santora and colleagues at the National Oceanic
The authors reconstruct historical seabird dispersal routes, showing that birds responded to temperature shifts by changes in range size rather than body mass. These trends are projected to persist, w...
🪸 Coral reef restoration is growing across the Western Indian Ocean, but most projects remain small, fragmented and difficult to compare.
Stronger regional coordination and long-term monitoring are essential for scaling effective reef recovery. #WorldReefAwarenessDay
