Seals help plug Antarctic water mystery

Elephant seals have helped scientists to demonstrate that fresh water from Antarctic's melting ice shelves slows the processes responsible for the formation of deep-water ocean currents that regulate global temperatures.

Ocean circulation implicated in past abrupt climate changes

There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ...

Wind-blown Antarctic sea ice helps drive ocean circulation

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than ...

When did the Andes mountains form?

The Andes have been a mountain chain for much longer than previously thought, new research from the University of Bristol, UK suggests.
