Locked in glaciers, ancient ice may return to life as glaciers melt
08-06-2007 · EurekAlert!The DNA of ancient microorganisms, long frozen in glaciers, may return to life as the glaciers melt, according to a paper published online this week in the Proceedings of the National Academy of Sciences by scientists at Rutgers, the State University of New Jersey, and Boston University. The article is scheduled to appear in the print edition on Tuesday, Aug. 14.

- Hundreds of Antarctic Peninsula glaciers accelerating as climate warms
06-05-2007 · EurekAlert!
Hundreds of glaciers on the Antarctic Peninsula are flowing faster, further adding to sea level rise according to new research published this week in the Journal of Geophysical Research. Climate warming that is already causing Antarctic Peninsula increased summer snow melt and ice shelf retreat is the most likely cause.

- Alaska glacier speed-up tied to internal plumbing issues, says CU-Boulder study
01-15-2008 · EurekAlert!
A University of Colorado at Boulder study indicates meltwater periodically overwhelms the interior drainpipes of Alaska's Kennicott Glacier and causes it to lurch forward, similar to processes that may help explain the acceleration of glaciers observed recently on the Greenland ice sheet that are contributing to global sea rise.

- Arctic expeditions find giant mud waves, glacier tracks
12-12-2007 · EurekAlert!
Scientists gathering evidence of ancient ice sheets uncovered a new mystery about what's happening on the Arctic sea floor today. Sonar images revealed that, in some places, ocean currents have driven the mud along the Arctic Ocean bottom into piles, with some "mud waves" nearly 100 feet across.

- Return to Europa: A closer look is possible
12-13-2007 · EurekAlert!
New research brings scientists closer to exploring the ice-covered ocean of Europa, one of Jupiter's moons. New methods in measuring gravity and magnetic fields, new radar sounding techniques, new technology being field tested in Antarctica, and findings of lower radiation levels and the presence of carbon dioxide (a key ingredient for life) on Europa make the moon a tantalizing prospect for exploration, as scientists explain at the 2007 meeting of the American Geophysical Union.

- Prototype space probe prepares to explore Earth's deepest sinkhole
03-07-2007 · EurekAlert!
Scientists return this week to the world’s deepest known sinkhole for tests of a NASA-funded robot called DEPTHX, designed to survey and explore for life in one of Earth’s most extreme regions and potentially in outer space. DEPTHX's technology could aid future space probes of Europa, where scientists believe deep holes in the ice could hold extraterrestrial life.

- Himalayan glacier melting observed from space
03-27-2007 · EurekAlert!
The Himalayan glaciers are melting under the effect of global warming. However, the extent of this melting remains difficult to assess from ground surveys owing to the great number of glaciers, the difficulty of access and the vastness of the mountain chain. IRD and CNRS scientists from the research units Great Ice and Legos have overcome these difficulties by using satellite imagery. This is the first step of a much more extensive project: evaluation and surveillance of the whole system of Himalayan glaciers .
