redOrbit Staff & Wire Reports - Your Universe Online Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience. Lead author Robin Bell, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, and her colleagues used ice-penetrating radar to discover the ragged...

An international team of scientists working in the most remote parts of Antarctica have discovered that masses of ice form underneath the ice sheet instead of on top, according to a study published Thursday in the journal Science.Liquid water locked deep under Antarctica's coat of ice regularly thaws, and then refreezes to the bottom, creating as much as half the thickness of the ice in some places, the researchers said. "We usually think of ice sheets like cakes -- one layer at a time added...

Researchers are preparing to explore an Antarctic mountain range that has never been seen before. The Gamburtsevs match the Alps in scale but no one has ever seen them because they are covered by up to 4km of ice. Now, researchers plan to use aircraft and seismic studies to map the mountain range. The U.S.-led multinational team of scientists from six nations is setting out on this deep-field survey to discover how such a massif could have formed and persisted in the middle of Antarctica....

Ancient water bodies may contain ecosystems adapted to life beneath more than two miles of ice Columbia -- Lying beneath more than two miles of Antarctic ice, Lake Vostok may be the best-known and largest subglacial lake in the world, but it is not alone down there. Scientists have identified more than 145 other lakes trapped under the ice. Until now, however, none have approached Vostok's size or depth. In the February 2006 issue of Geophysical Review Letters, scientists from the...
