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,...

redOrbit Staff & Wire Reports - Your Universe Online A rapidly melting region of the West Antarctic Ice Sheet appears to have reached an irreversible state of decline, meaning that nothing can be done to prevent the glaciers from melting into the sea, researchers from NASA and the University of California, Irvine claim in a new study. The researchers came to that conclusion after analyzing four decades worth of data on glaciers located in the Amundsen Sea sector of West Antarctica....

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...

NASA IceBridge Science Team Making Plans For The Future

George Hale - NASA Twice a year, members of NASA's Operation IceBridge science team meet to discuss the mission's goals and progress, to define plans for upcoming field campaigns and get feedback from the scientific community. The science team met from January 28 through 30, 2014, at NASA's Goddard Space Flight Center in Greenbelt, Md. This was the first meeting for IceBridge's new science team, which will serve from 2014 until 2017. IceBridge's previous science team was selected in...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

Ice sheets have been losing mass at an accelerated rate over the past two decades, and these changes could soon become the dominant contributor to rising global sea levels, a NASA-funded study has discovered. The results of the nearly 20-year satellite research project--the longest study ever to track changes in polar ice sheet mass--showed that ice sheets in Greenland and the Antarctic lost an average of 475 gigatons of combined mass annually. Each gigaton is roughly equal to 2.2 trillion...
