Basal Melt Responsible For Antarctic Ice Shelf Loss
redOrbit Staff & Wire Reports - Your Universe Online The majority of Antarctica’s ice loss is caused by warm ocean waters eating away at the undersides of ice shelves, not the sudden release and breaking away of ice masses from glaciers...

Stevens Institute of Technology continues to shape the policy discussion around climate change and extreme weather, as Dr. Philip Orton and Dr. Nickitas Georgas contributed advanced scientific research to inform the proposals outlined in “A Stronger, More Resilient New York,” a major report released this week by New York City Mayor Michael Bloomberg. The report outlines more than 250 specific recommendations to fortify the city against climate events. Hoboken, N.J. (PRWEB) June 13,...
PASADENA, Calif., June 13, 2013 /PRNewswire-USNewswire/ -- Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the...
NASA A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as Bedmap—that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation...
April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...
Lee Rannals for redOrbit.com - Your Universe Online Ocean data collected over 135 years ago by the crew of the HMS Challenger oceanographic expedition has helped confirm global warming. Researchers from NASA and the University of Tasmania used the data to provide further confirmation that humans have played a part in today's changing global climate. The team combined the ship's measurements of ocean temperatures with modern observations from the international Argo array of ocean...
Alaska’s melting glaciers remain one of the largest contributors to the world’s rising sea levels, say two University of Alaska Fairbanks geophysicists. UAF Geophysical Institute researchers Anthony Arendt and Regine Hock joined 14 scientists from 10 countries who combined data from field measurements and satellites to get the most complete global picture to date of glacier mass losses and their contribution to rising sea levels. “Sea level change is a pressing societal...
April Flowers for redOrbit.com - Your Universe Online Scientists have known for some time that melting glaciers are contributing to the global sea-level rise. However, the amount being contributed by each region of the planet has never before been calculated with the accuracy of a new study led by researchers at the University of Colorado at Boulder and Clark University. Ninety-nine percent of Earth’s land ice is locked up in the Greenland and Antarctica ice sheets. The study,...
WASHINGTON, May 16, 2013 /PRNewswire-USNewswire/ -- A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259...
April Flowers for redOrbit.com - Your Universe Online If someone said “climate refuge” to you, what would come to mind? More than likely, the image of someone from a small tropical island in the Pacific, or of a low-lying delta like in Bangladesh – places where residents have been forced out of their homes by sea-level rise. The strict definition of a refugee in international law, according to a report by The Guardian, is rather narrow and typically includes only people displaced...
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...

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
