How stable is deep ocean circulation in warmer climate?

If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe—a scenario that has occurred during past cold glacial periods.

Arctic ice melt is changing ocean currents

A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows. The current is part of a delicate Arctic environment that is now flooded with fresh water, an ...

North Atlantic Current may cease temporarily in the next century

The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and ...

Could we cool the Earth with an ice-free Arctic?

The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. IIASA researchers explored strategies for cooling down the oceans ...

Fresh water found in the Norwegian Sea

When we the found fresh water leaking from the seabed, we were very surprised," explains scientist and marine geologist Wei-Li Hong at the Geological Survey of Norway (NGU).

Following the food trail to help right whales

Scientists are gathering data on a flea-sized, fat-rich organism that could be key to predicting where North Atlantic right whales venture in their search for food in the southern Gulf of St. Lawrence.

Scientists discover the biggest seaweed bloom in the world

Scientists led by the USF College of Marine Science used NASA satellite observations to discover the largest bloom of macroalgae in the world called the Great Atlantic Sargassum Belt (GASB), as reported in Science.
