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...

NASA's Rover Prototype 'GROVER' To Explore Greenland Ice Sheet
2013-05-02 12:30:17

NASA NASA's newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, will roam the frigid landscape collecting measurements to help scientists better understand changes in the massive ice sheet. This autonomous, solar-powered robot carries a ground-penetrating radar to study how snow accumulates, adding layer...

NASA's Arctic IceBridge Campaign Closes With Much Success
2013-04-30 14:14:59

Lee Rannals for redOrbit.com — Your Universe Online NASA said its Operation IceBridge team has finished up another successful campaign to continue collecting data of Arctic ice measurements. IceBridge was started in 2009 to help continue and expand a dataset started by NASA's Ice, Cloud and Land Elevation Satellite (ICESat) in 2003. During this year's campaign, the team measured sea ice, mapped sub-ice bedrock and gathered data on Greenland's glaciers by flying science missions...

1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Ice Flow Critical To Health Of The Planet
2013-04-10 10:43:29

April Flowers for redOrbit.com - Your Universe Online "Go with the flow" has been a standard, if somewhat glib, piece of nearly universally applicable advice for a long time — and never more so than now. Shujie Wang, a geography doctoral student at the University of Cincinnati's McMicken College of Arts & Sciences, recently led a team of researchers who discovered that the best way to monitor the environmental health of the Antarctic is just to go with the flow. The ice...

Greenland's 2012 Record Ice Melt Due To Thin Cloud Cover
2013-04-04 11:15:46

April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

Arctic Ice Cover Continues To Shrink
2013-04-04 08:52:02

[ Watch the Video: An Interesting Year for Arctic Sea Ice ] April Flowers for redOrbit.com - Your Universe Online The Arctic Ocean's ice cover shrank to its lowest extent on record last September at the end of the northern hemisphere summer. This continues a long-term trend diminishing the ice to about half the size of the average summertime extent from 1979 to 2000. The sea ice refreezes during the cold and dark Arctic winter, achieving its maximum extent usually in late February or...

Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

Greenland's Peripheral Glaciers Also Contribute Significantly To Sea-Level Rise
2013-03-18 13:39:33

Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island...
