Major Increase In West Antarctic Glacial Loss
2014-03-28 17:26:44

American Geophysical Union Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, scientists report this month in Geophysical Research Letters, a journal of the American Geophysical Union. Pine Island Glacier, the most active of the studied...

Greenland river discharge
2014-03-19 03:59:06

redOrbit Staff & Wire Reports - Your Universe Online After growing frustrated attempting to measure the amount of water draining from Greenland’s melting ice sheet, one UCLA graduate student has developed a new method of measuring the width of a river over an extended period of time using freely available imagery from orbiting satellites. Currently, the volume of water running through a river at any given time is determined using a series of ground-based measurements. Hydrologists...

Greenland Ice Sheet Receding And Is Now Considered Unstable
2014-03-17 10:26:10

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal Nature Climate Change, the last stable section of the Greenland ice sheet is receding and now considered unstable – a development that could portend even more ice loss in the future and significant sea level rise. The report focused on a key ice stream in the Greenland ice sheet. Ice streams drain an ice basin from the interior of the sheet, in the same way that regular streams drain water...

redOrbit Staff & Wire Reports - Your Universe Online Scientists working on NASA’s Operation IceBridge mission are en route to Greenland to kick off this year’s Arctic land and sea ice data collection efforts, officials from the US space agency announced on Wednesday. On Monday, the researchers departed from the Wallops Flight Facility in Wallops Island, Virginia on board the agency’s P-3 research aircraft. They will be collecting and reporting valuable information on rapidly...

WASHINGTON, March 12, 2014 /PRNewswire-USNewswire/ -- Researchers aboard NASA's P-3 research aircraft left the agency's Wallops Flight Facility in Wallops Island, Va., March 10 for Greenland to begin a new season of collecting data on Arctic land and sea ice. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The mission, known as Operation IceBridge, is to gather data on changes to polar ice and maintain continuity of measurements between NASA's Ice, Cloud and Land Elevation...

Greenland Jakobshavn Glacier
2014-03-12 04:40:59

Lee Rannals for redOrbit.com - Your Universe Online New data obtained by NASA's Operation IceBridge program is shedding new light on how ice sheets in Greenland are changing. Scientists used satellite observations and ice thickness measurements made by Operation IceBridge to determine the rate at which ice flows through Greenland’s glaciers into the ocean. The findings have shown how glacier flow is affecting the Greenland Ice Sheet and that this process is being dominated by a small...

Greenland Ice Sheet
2014-02-07 04:35:58

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Nature say that ocean warming could be causing a four-fold increase in ice loss on the Greenland Ice Sheet. The Greenland Ice Sheet is about a 2-mile thick layer of ice that covers the country. Glaciers that drain the ice sheet plunge into coastal fjords that are about 2,000 feet deep, helping to expose the ice sheet edges that contact the ocean. Oceanographers from Woods Hole Oceanographic...

World's Fastest Moving Glacier Found In Greenland
2014-02-03 12:45:37

[ Watch the Video: Fastest Glacier In The World ] Lee Rannals for redOrbit.com - Your Universe Online Researchers from the University of Washington and the German Space Agency (DLR) say that a Greenland glacier is slipping off into the ocean at a speed never before seen. The scientists measured the speeds of Jakobshavn Isbræ (Jakobshavn Glacier) in Greenland and found that this glacier is the fastest moving ice sheet ever recorded. “We are now seeing summer speeds more than 4...

Pine Island Glacier Retreating
2014-01-14 14:44:51

Lee Rannals for redOrbit.com - Your Universe Online Antarctica’s Pine Island Glacier (PIG) is now in an irreversible retreat, according to a study published in the journal Nature Climate Change. PIG is one of the biggest single contributors to global sea-level rise, and the latest study says that it could add as much as 0.39-inches to ocean levels in 20 years. “Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating rate, so that at present it is...

greenland aquifer

redOrbit Staff & Wire Reports - Your Universe Online An “extensive” new aquifer discovered in the Greenland Ice Sheet by an international team of researchers contains liquid water year-round, according to research published in Sunday’s edition of the journal Nature Geoscience. According to the researchers, the reservoir fills 27,000 square miles and is known as a “perennial firn aquifer” because water persists inside the firn – layers of ice and snow that don’t melt...
