Giant iceberg set to calve from Larsen C ice shelf

A huge iceberg, roughly the size of Norfolk, looks set to break away from the Larsen C ice shelf on the Antarctic Peninsula.  Larsen C is more than twice the size of Wales. Satellite observations from December 2016 show ...

Getting to know the Getz Ice Shelf

As scientists and crew with NASA's Operation IceBridge mission prepared for a research flight on Nov. 5, 2016, the weather in Punta Arenas, Chile, was cold, wet, and windy. But when they reached their survey site in West ...

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.

Study helps explain sea ice differences at Earth's poles

Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern ...

Improved modelling of ice-ocean processes

Pine Island Glacier in West Antarctica is currently one of the single biggest contributors to sea-level rise with an estimated volume loss of 1.2mm sea-level equivalent per decade. The loss is caused, at least partly, by ...
