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...

WASHINGTON, Oct. 31, 2013 /PRNewswire-USNewswire/ -- For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) NASA's C-130 research aircraft flew from the Wallops Flight Facility in Wallops Island, Va., to Greenland Wednesday where they will conduct survey flights to collect data that will improve...

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...

Global Warming Could Explain Exponential Sea Ice Growth
2013-09-18 12:28:55

Michael Harper for redOrbit.com - Your Universe Online In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National...

British Antarctic Survey To Launch Long-Term Survey Of Pine Island Glacier
2013-09-09 10:34:32

Lawrence LeBlond for redOrbit.com - Your Universe Online An ambitious science mission is about to begin in Antarctica, with team members from the British Antarctic Survey (BAS) looking to understand why the continent’s Pine Island Glacier (PIG), located on the West Antarctic Ice Sheet, is rapidly diminishing. The goal of the mission is to ultimately discern if rapid ice loss will continue to increase or if it will slow down. The team argues that this research is crucial for...
