Latest Ice sheet Stories
West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East Antarctica.
With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well.
An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study.
The bedrock hidden beneath the thick ice sheets covering Greenland and Antarctica has intrigued researchers for years. Scientists are interested in how the shape of this hidden terrain affects how ice moves -- a key factor in making predictions about the future of these massive ice reservoirs and their contribution to sea level rise in a changing climate.
Trapped air bubbles squirting out of disappearing glacial ice causes a sizzling noise that might provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar environments.
There have been many studies telling us how small the Greenland ice sheet is today. A new study, published in the journal Geology, reveals that the ice sheet was actually smaller between 3,000 and 5,000 years ago.
Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer.
The arrival of NASA scientists and aircraft at McMurdo Station in Antarctica on Saturday marks the beginning of the 2013 Operation IceBridge field campaign in that region, the US space agency has announced.
The discovery of hundreds of kilometers worth of channels beneath a floating ice shelf in Antarctica could help experts understand how the ice will respond to changes in environmental conditions.
