NASA provides new perspectives on the earth's changing ice sheets

It is widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. What most do not know is that until just six years ago, we had no real way of measuring whether the ice sheets were shrinking or growing, or at what rate. Waleed Abdalati of NASA's Goddard Space Flight Center, provides an overview of recent findings at the American Geophysical Union meeting, December 11 at 7:15 p.m. EST (session C14B-02).

1. Lakes beneath Antarctic ice sheets found to initiate and sustain flow of ice to ocean
   02-21-2007 · EurekAlert!
   Geophysicists Robin Bell and Michael Studinger from the Lamont-Doherty Earth Observatory, a part of the Earth Institute at Columbia University, led a team that discovered four large, subglaical lakes that for the first time the link these water bodies locked beneath miles of ice, to fast flowing ice streams in Antarctica. Together with colleagues from NASA, the University of New Hampshire and the University of Washington, the scientists found that, in four separate cases, lakes appear to contribute to the formation of ice streams.

2. Greenland Ice Sheet Still Losing Mass
   09-29-2006 · ScienceDaily
   Data gathered by a pair of NASA satellites orbiting Earth show Greenland continued to lose ice mass at a significant rate through April 2006, and that the rate of loss is accelerating, according to a new University of Colorado at Boulder study.

3. LSU professor looks for life in and under antarctic ice
   08-31-2007 · EurekAlert!
   Antarctica is home to the largest body of ice on Earth. Prior to approximately 10 years ago, no one thought that life could exist beneath the Antarctic ice sheets, which can be more than two miles thick in places, because conditions were believed to be too extreme. However, Brent Christner, assistant professor of biological sciences at LSU, has spent a great deal of time in one of the world's most hostile environments conducting research that proves otherwise.

5. Arizona State University scientist finds Martian ice is patchy and variable
   05-02-2007 · EurekAlert!
   For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.

   Using echo-sounding equipment to create images and maps of areas below the ocean floor, researchers have begun to unravel a new story about the Antarctic Ice Sheet.Images of areas below the Eastern Ross Sea, next to West Antarctica, provide evidence that the subcontinent was involved in the general growth of the Antarctic Ice Sheet as it formed many millions of years ago, according to scientists at the University of California, Santa Barbara. The National Science Foundation provided funding for the project.
