East Antarctica Is Pushing Around Its Softer-Mantled Western Half
2013-12-12 07:51:20

April Flowers for redOrbit.com - Your Universe Online It's easy to know what to do when half-siblings are pushing each other around, but what do you do about half-continents? A team of researchers, led by Ohio State University, have discovered that East Antarctica is pushing West Antarctica around. 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...

ESA CryoSat Mission Confirms Antarctic Ice Loss Is On The Rise
2013-12-12 06:08:21

Alan McStravick for redOrbit.com - Your Universe Online 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. The team presenting these findings conducted their research with the Natural Environment Research Council’s Center for...

The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online 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 discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Airborne Radar Looks Through Thick Ice During NASA Polar Campaigns
2013-12-03 15:23:42

NASA 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. NASA has been monitoring Antarctic and Arctic ice since 2009 with the Operation IceBridge airborne mission. Although the primary...

Warm Water Causes Arctic Glaciers To Sizzle As They Melt
2013-11-28 06:11:28

[ Watch the Video: Melting Glacial Ice Has Its Own Sound ] April Flowers for redOrbit.com - Your Universe Online One of the most prominent sounds of a warming planet has been recorded and identified by scientists at the University of Alaska: the sizzle of glacial ice as it melts into the sea. Trapped air bubbles squirting out of the disappearing ice causes a noise that might provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar...

Arctic Fossil Record Traces Greenland Ice Sheet's Past
2013-11-23 05:24:05

April Flowers for redOrbit.com - Your Universe Online 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. Surprisingly, the sheet was as small during this period as it has ever been in recent history. The international research team used a new technique they developed for interpreting the Arctic fossil record. “What’s...

Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer Predictions of sea level rise could become more accurate, thanks to new insight into how glacier movement is affected by melting ice in summer. Studies of the Greenland ice sheet, including during a record warm summer, are helping scientists better understand how summer conditions affect its flow. This is important for predicting the future...

Operation IceBridge 2013 Campaign Begins At McMurdo Station
2013-11-17 05:02:11

redOrbit Staff & Wire Reports - Your Universe Online 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. As part of the mission, daily survey flights will take place through November 26 on a NASA P-3 research aircraft departing from a base of operations at the National Science Foundation (NSF) facility. Researchers traveling on...

Channels In Antarctic Ice Shelf Will Help Predict Future Of Antarctic Ice
2013-10-07 04:31:47

redOrbit Staff & Wire Reports - Your Universe Online 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, according to a study published Sunday in the journal Nature Geoscience. Researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey and the...
