Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface. The map gives a view of the landscape beneath the ice, and incorporates decades of survey data acquired by planes, satellites, ships and even people on dogsleds. In the map, the highest elevations are marked in red/black, while the light blue color shows the extent of the continental shelf.  The lowest elevations are dark blue, some of which lie below today's seal...

Researchers funded by the National Science Foundation may have finally found how Antarctica´s Gamburtsev Subglacial Mountains were formed, a conundrum that has plagued scientists since they were first discovered in 1958. The international team of scientists explored the subglacial mountain range -- buried under nearly 10,000 feet of ice -- during the International Polar Year (2007-2009) by using two twin-engine aircraft equipped with ice penetrating radar, gravity meters and...

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...

New research by scientists in Britain and China reveals evidence of how the East Antarctic ice sheet initially formed. The work provides a snapshot of terrain that has lain hidden miles beneath the ice for millions of years, when rivers ran through mountain valleys that were oddly similar to the modern European Alps. The scientists used radar to map an area of the Gamburtsev mountains, believed to be where the ice originated. The region would have been cold enough to support the...

Scientists said on Tuesday that Antarctica's ice is covering up jagged mountains the size of the Alps, providing new clues about the vast ice sheet that will raise world sea levels if even a fraction of it melts, Reuters reported. First detected by Russian scientists 50 years ago at the heart of the East Antarctic ice sheet using radar and gravity sensors, the experts made the first detailed maps of the Gamburtsev subglacial mountains. Fausto Ferraccioli, a geophysicist at the British...

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....
