Deep waters spiral upward around Antarctica

Since Captain James Cook's discovery in the 1770s that water encompassed the Earth's southern latitudes, oceanographers have been studying the Southern Ocean, its physics, and how it interacts with global water circulation ...

Analyzing ocean mixing reveals insight on climate

Scientists at Los Alamos National Laboratory have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean.

'Dead zones' found in Atlantic open waters

A team of German and Canadian researchers have discovered areas with extremely low levels of oxygen in the tropical North Atlantic, several hundred kilometres off the coast of West Africa. The levels measured in these 'dead ...

Swirling currents deliver phytoplankton carbon to ocean depths

Just as crocus and daffodil blossoms signal renewal and the start of a warmer season on land, a similar "greening" event—a massive phytoplankton bloom—unfolds each spring in the Atlantic Ocean from Bermuda to the Arctic. ...
