New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas. Iceberg production and melting causes 2,800 cubic kilometers of ice to leave the Antarctic ice sheet every year. Most of this is replaced by snowfall but any imbalance contributes to a change in global sea level. For many decades, experts have believed that the most important process...

Pine Island Glacier Is Melting From Below
2013-09-13 04:27:05

[ Watch the Video: Warm Ocean Melting Pine Island Glacier ] redOrbit Staff & Wire Reports - Your Universe Online The floating ice shelf in a remote region of Antarctica is being melted by warm ocean water, not hot air, an international team of researchers report in the latest edition of the journal Science. As described in the new study, an expedition to Pine Island Glacier allowed scientists to get an up-close-and-personal look beneath the ice of one of the most difficult to...

ESA’s CryoSat Mission Provides New Insights Into Our Fragile Polar Regions
2013-09-11 11:48:06

[ Watch The Video - Arctic Ice Thickness 2010 to 2013 ] ESA Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin. Although satellites have witnessed a downward trend in the extent of sea ice over the last two decades, it is essential to have accurate information on the mass or volume of ice being lost. This is a more accurate measure of the...

Subglacial Antarctic Lake Sediments Contain Diversity Of Ancent Lifeforms
2013-09-11 09:28:57

April Flowers for redOrbit.com - Your Universe Online A group of British scientists has for the first time found evidence of diverse lifeforms dating back nearly 100 thousand years in subglacial lake sediment. For decades, scientists have been fascinated by the idea that extreme lifeforms might exist in the cold and dark lakes hidden miles beneath the Antarctic ice sheet. Direct sampling of these lakes in the interior of Antarctica, however, presents major technological challenges even...

Important Role In Polar Ocean Carbon Budgets Played By Micro-gels From Tiny Arctic And Antarctic Ice Algae
2013-09-10 10:47:21

Aarhus University Secretion of polysaccharides from the micro community living within the sea ice stick organism together and forms greater particles introducing a rapid transport of carbon to the seafloor. New research now makes it possible to forecast the importance for the global carbon budget of this transport. A community of microscopic algae and bacteria thrives within the Arctic and Antarctic pack ice. These ice-organisms are adapted to growing on the ice crystal surfaces and...

British Antarctic Survey To Launch Long-Term Survey Of Pine Island Glacier
2013-09-09 10:34:32

Lawrence LeBlond for redOrbit.com - Your Universe Online An ambitious science mission is about to begin in Antarctica, with team members from the British Antarctic Survey (BAS) looking to understand why the continent’s Pine Island Glacier (PIG), located on the West Antarctic Ice Sheet, is rapidly diminishing. The goal of the mission is to ultimately discern if rapid ice loss will continue to increase or if it will slow down. The team argues that this research is crucial for...

West Antarctica's Ice Sheet 20 Million Years Older Than Previosuly Estimated
2013-09-05 07:26:16

April Flowers for redOrbit.com - Your Universe Online A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought. These results, published in Geophysical Research Letters, mark a paradigm shift for our understanding of the Earth’s great global ice sheets. Ice sheets first grew on the West Antarctic subcontinent around 34...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

Grand Canyon Found Lurking Beneath Greenland's Ice Sheet
2013-08-30 04:06:35

[ Watch the Video: Greenland’s Mega Canyon ] redOrbit Staff & Wire Reports - Your Universe Online One of the largest canyons in the world has been discovered beneath the Greenland ice sheet, according to new research appearing in the latest edition of the journal Science. Lead author Jonathan Bamber, a professor at the University of Bristol’s School of Geographical Sciences, and colleagues report the canyon is at least 460 miles (750km) long, up to 2,600 feet (800m) deep in...

Columbia Plateau
2013-04-19 16:35:47

The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Meltwater
2009-07-06 17:15:30

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
