Seaweed Surges May Alter Arctic Fjord Carbon Dynamics
Climate change–accelerated seaweed growth could cause seaweed-dependent microbes to proliferate and consume more oxygen, leading to a rise in oxygen-starved zones.
Have We Finally Found the Source of the “Sargassum Surge”?
The complexity of modeling the tropical Atlantic makes identifying the source of the ongoing seaweed blooms difficult.
The Uncertain Fate of the Beaufort Gyre
Climate models produce widely varying predictions for what will happen to this influential ocean current, but most models predict it will weaken or stop.
A Great Whale Conveyor Belt Transports Nutrients Across Oceans
Baleen whales shift huge amounts of nutrients, including nitrogen, from high-latitude feeding waters to tropical breeding areas.
A Leap Toward Next-Generation Ocean Models
GPU-optimized ocean modeling achieves decade-long simulations in a day, enabling mesoscale-resolving climate simulations that open new opportunities for long-term planning in a changing climate.
Coastal Models Quantify How Natural Islands Respond to Sea Level Rise
Coastal models enhance understanding of future flooding frequency on atoll islands, paving the way to explore the limits of adaptation in the face of rising sea levels and climate change.
Trump Moves to Allow Seabed Mining in International Waters
A new executive order aims to establish the United States “as a global leader in seabed mineral exploration and development both within and beyond national jurisdiction.”
Avalanches of Microplastics Carry Pollution into the Deep Sea
Scientists observed a once-theorized process ferrying microplastics into the deep ocean.
Upwelling Near Fronts Initiate Offshore Phytoplankton Blooms
A new study finds that phytoplankton blooms, often seen near the separation point of western boundary currents, are supported by nutrient supply upwelling and cross-shelf transport.
