National Science Foundation A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot--dubbed Yeti--could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could...

Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder. The new study showed ice sheets like the Greenland Ice Sheet can respond to such warming on the order of decades rather than the centuries projected by conventional thermal models. Ice flows more readily as...

Researchers learning more about how water beneath glaciers contributes to ice loss Scientists who study the melting of Greenland's glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined. Researchers previously thought that meltwater simply lubricated ice against the bedrock, speeding the flow of glaciers out to sea. Now, new studies have revealed that the effect of meltwater on acceleration and ice loss -- through fast-moving...

The conference showed that the Arctic climate is changing rapidly in a number of different ways: The recent rate of decrease in thickness and volume of the Arctic sea ice has been faster than the rate of aerial shrinkage determined from satellites. Given that the present trend of melt continues, some models indicate that it is quite likely that the Arctic Ocean could be ice free in the summer time as early as 2015-16. There has been a rapid increase in the mass-loss from the Greenland ice...

Researchers Make First Observations of Surface Meltwater Cutting through the Ice Sheet to Lubricate the BottomResearchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Washington (UW) have for the first time documented the sudden and complete drainage of a lake of meltwater from the top of the Greenland ice sheet to its base.From those observations, scientists have uncovered a plumbing system for the ice sheet, where meltwater can penetrate thick, cold ice and...

BUENOS AIRES, Argentina (Reuters) - Rescue workers battled with rough Antarctic weather on Monday in an effort to rescue two Argentine men who fell into a glacial crevasse believed to be at least 165 feet deep. An Argentine scientist and a naval officer were traveling between research bases on Saturday when their snowmobile plummeted through the snow cover. Three other people swerved away in time and were rescued from the glacier by helicopter on Sunday. No contact has been made...
