British scientists plan to use a yellow submarine to explore beneath a giant melting Antarctic glacier whose collapse could raise sea levels 4 inches. The scientists hope to find out why Pine Island Glacier, flowing west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, is melting so quickly at its base, said the British Antarctic Survey, Britain's national Antarctic operator. The 23-foot-long, robotic yellow submarine, nicknamed Autosub, will map out...

 Researchers watching the loss of ice flowing out from the giant island of Greenland say that the amount of ice lost this summer is nearly three times what was lost one year ago.The loss of floating ice in 2008 pouring from Greenland's glaciers would cover an area twice the size of Manhattan Island in the U.S., they said."We now know that the climate doesn't have to warm any more for Greenland to continue losing ice," Box said.  "It has probably passed the point where it could...

Scientists say that enormous floods beneath the Antarctic ice sheet can now be linked directly to the speed at which that ice moves towards the ocean. The giant Byrd Glacier in east Antarctica sped up just as two lakes under the ice overflowed, according to Leigh Stearns and colleagues. They say the floodwater acts as a lubricant, easing the ice over the bedrock. Experts believe the more ice the Polar Regions dump in the ocean, the higher the waters will rise. Ice behavior in response to a...

PASADENA, Calif. -- Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study by NASA and university scientists. In a first-of-its-kind study, an international team led by Eric Rignot of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the University of California, Irvine, estimated changes in Antarctica's ice mass between 1996...

Increasing amounts of ice mass have been lost from West AntarcticaIncreasing amounts of ice mass have been lost from West Antarctica and the Antarctic Peninsula over the past ten years, according to research from the University of Bristol and published online this week in Nature Geoscience. Meanwhile the ice mass in East Antarctica has been roughly stable, with neither loss nor accumulation over the past decade.Professor Jonathan Bamber at the University of Bristol and colleagues estimated...

NASA -- Scientists using satellite data have now created the most detailed maps ever produced of the vast snow-covered Antarctic continent. The maps reveal unprecedented views of surface features that provide clues to how and why the continent's massive ice sheets and glaciers are changing. Researchers can now decipher the intricate history of ice movements in the just-released "Mosaic of Antarctica," which uses images from the Moderate Resolution Imaging Spectrometer onboard NASA's Terra and...

NASA -- At 32 degrees Fahrenheit, or 0 Celsius, ice changes to water. This simple, unique fact dominates the climate in Earth's polar regions. Using satellites to detect changes over time, NASA researchers and NASA-funded university scientists have found that Earth's ice cover is changing rapidly near its poles. Recent studies point to new evidence of relationships between climate warming, ice changes and sea level rise. Two researchers from NASA Goddard Space Flight Center (GSFC),...

NASA -- When people talk about something moving at a glacial pace, they are referring to speeds that make a tortoise look like a hare. While it is all relative, glaciers actually flow at speeds that require time lapses to recognize. Still, researchers who study Earth's ice and the flow of glaciers have been surprised to find the world's fastest glacier in Greenland doubled its speed between 1997 and 2003. The finding is important for many reasons. For starters, as more ice moves from...
