Climate Models Reveal That Icebergs Once Reached As Far South As Florida

Chuck Bednar for redOrbit.com - Your Universe Online As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research...

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...

Greenland Ice Sheet
2014-09-30 04:38:53

Brett Smith for redOrbit.com - Your Universe Online Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however, and found that the ice sheet may be melting faster than previously thought. Published in the journal Nature Communications, the team’s report is based on the calculation, derived from ground surveys,...

April Flowers for redOrbit.com - Your Universe Online Data from the European Space Agency's (ESA) CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute (AWI) in Germany. The new maps, which are the most complete to ever be created from a single satellite mission, reveal the ice sheets are losing volume at an unprecedented yearly rate (approximately 500 cubic kilometers). The...

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study
2014-06-26 03:26:40

Oregon State University A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth's orbit around the sun. Results of the study,...

Analyzing The Role Of The Ocean In Greenland Ice Sheet Melting
2014-06-24 06:51:19

redOrbit Staff & Wire Reports - Your Universe Online Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and while warmer atmospheric conditions are to blame for increased melting at the glacier’s surface, scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost. According to researchers from the Woods Hole Oceanographic Institution (WHOI) and the University of Oregon,...

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience. Lead author Robin Bell, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, and her colleagues used ice-penetrating radar to discover the ragged...

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...

Greenland ice sheet

April Flowers for redOrbit.com - Your Universe Online In 1889 and 2012, there was large-scale melting of the Greenland ice sheet. Scientists have assumed these events were driven by warming alone, but a new study from the Thayer School of Engineering at Dartmouth College and the Desert Research Institute reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events. The findings, published in the Proceedings of the National...

WASHINGTON, May 19, 2014 /PRNewswire-USNewswire/ -- Scientists at NASA and the University of California, Irvine (UCI), have found that canyons under Greenland's ocean-feeding glaciers are deeper and longer than previously thought, increasing the amount of Greenland's estimated contribution to future sea level rise. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "The glaciers of Greenland are likely to retreat faster and farther inland than anticipated, and for much longer,...

University of California - Irvine Major UCI-NASA work reveals long, deep valleys connecting ice cap to the ocean Greenland's icy reaches are far more vulnerable to warm ocean waters from climate change than had been thought, according to new research by UC Irvine and NASA glaciologists. The work, published May 18 in Nature Geoscience, shows previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet. The bedrock canyons sit well below sea level,...
