George Hale, NASA's Goddard Space Flight Center Thanks in part to support from NASA and the National Science Foundation, scientists have produced the first-ever detailed maps of bedrock beneath glaciers in Greenland and Antarctica. This new data will help researchers better project future changes to glaciers and ice sheets, and ultimately, sea level. Researchers at the Center for Remote Sensing of Ice Sheets, or CReSIS, at the University of Kansas in Lawrence, Kansas, recently built...

NASA IceBridge Wraps Up Arctic Field Campaign
2014-05-29 03:43:26

By George Hale, NASA Starting With Sea Ice IceBridge's campaign began on Mar. 10 when NASA's P-3 research aircraft left Wallops for Thule. For the first part of the campaign, researchers studied Arctic sea ice from Thule and Fairbanks, Alaska. Early in each campaign IceBridge spends a week in Alaska to survey sea ice north of Alaska. In addition, researchers study sea ice conditions across the entire Arctic Basin traveling from Thule to Fairbanks and back. IceBridge's sea ice...

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...

Study Explains Surprising Acceleration Of Greenland's Inland Ice
2013-07-24 14:49:30

NASA [ Watch The Video Greenland Ice Flow ] Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, a new NASA-funded study finds. During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or "snouts," of Greenland glaciers as they flow into the ocean along the western coast. Now, the new research shows that the interior regions are also...

Glacier Geometry Linked To Diverse Calving Patterns
2013-07-23 05:24:37

April Flowers for redOrbit.com - Your Universe Online Large stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean in events over the coming decades that could aggravate sea level rise. The new study, published in Nature Geoscience, describes new iceberg calving simulations from the University of Michigan. "If this starts to happen and we're right, we might be closer to the higher end of sea level rise estimates for...

Iceberg Production Modeled For Greenland Glaciers
2013-05-09 05:59:32

April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...

Study on Jakobshavn Isbrae supports growing evidence that calving glaciers are particularly sensitive to climate change Large, marine-calving glaciers have the ability not only to shrink rapidly in response to global warming, but to grow at a remarkable pace during periods of global cooling, according to University at Buffalo geologists working in Greenland. The conclusion stems from new research on Jakobshavn Isbrae, a tongue of ice extending out to sea from Greenland's west coast. Through...

NASA-funded researchers monitoring Greenland's Jakobshavn Isbrae glacier report that a 7 square kilometer (2.7 square mile) section of the glacier broke up on July 6 and 7. The calving front "“ where the ice sheet meets the ocean "“ retreated nearly 1.5 kilometers (a mile) in one day and is now further inland than at any time previously observed. The chunk of lost ice is roughly one-eighth the size of Manhattan Island, New York. Research teams led by Ian Howat of the Byrd Polar...

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...

Scientists are trying to determine what occurred in Greenland's history to cause its glaciers to rapidly melt, and what implications it might have for the earth's future in light of looming global warming. In 2005, scientists noticed that Greenland's Helheim Glacier had nearly doubled in speed as it moved through a river at a pace of 100 feet per day. The rapid movement caught researchers by surprise and sparked concerns that it could be a sign of a massive melting of the Greenland's ice...
