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...

Surprising Resilience Shown By Alaska Tundra After Unprecedented Fire
2013-08-30 09:20:21

Institute of Arctic Biology Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska’s North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition according to University of Alaska Fairbanks scientist Syndonia “Donie” Bret-Harte and colleagues in a recent scientific paper. In April 2007, a wall of smoke was visible 23 miles south of the fire at the UAF Institute of Arctic Biology Toolik Field Station...

Sea Ice Decline Changing The Vegetation Of The Arctic
2013-08-23 10:26:03

Geophysical Institute, University of Alaska Fairbanks Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists. Uma Bhatt, an associate professor with UAF’s Geophysical Institute, and Skip Walker, a professor at UAF’s Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic. “Our...

Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor. The research by scientists at UNSW and the Australian Antarctic Division predicts that biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm. The study, Light-driven tipping points in polar ecosystems, will be published in the journal...

QUEBEC CITY, July 26, 2013 /CNW Telbec/ - The Canadian Coast Guard Ship (CCGS) Amundsen will celebrate its 10(th) Anniversary as a research icebreaker this year as it departs Quebec City on 26 July for its annual expedition to the Canadian Arctic. Over the last 10 years, the CCGS Amundsen has been a major catalyst in revitalizing Canadian Arctic science by giving Canadian researchers and their international collaborators unprecedented access to the Arctic Ocean. Thanks to major...

Russia Blocks Antarctic Sanctuary
2013-07-17 08:34:56

redOrbit Staff & Wire Reports - Your Universe Online Russia has blocked attempts to establish marine reserves in the Ross Sea and Eastern Antarctica, preventing the formation of what would have become the world's largest ocean sanctuary. According to BBC News, the Russian representative challenged the legality of a meeting that would have allowed for the creation of the reserves. The three-day-long conference, held in Bremerhaven, Germany was called by the Commission for the...

Swamp-Like Water System Revealed Under Antarctica's Thwaites Glacier
2013-07-09 14:43:50

Lee Rannals for redOrbit.com - Your Universe Online While using an innovative radar analysis method to accurately image the sub-glacial water system under West Antarctica's Thwaites Galcier, scientists discovered a swamp-like canal system beneath the ice. The scientists, from The University of Texas at Austin's Institute for Geophysics, reported in the Proceedings of the National Academy of Sciences (PNAS) that the swamp-like canal is several times as large as Florida's Everglades....

Subglacial Life Found In Ice Cores From Lake Vostok, Antarctica
2013-07-05 11:58:56

Lawrence LeBlond for redOrbit.com - Your Universe Online Lake Vostok, the largest of some 400 subglacial lakes scattering Antarctica's frozen depths, has been the subject of ambitious research for at least the past 15 years. Lying more than 2 miles below the surface, the lake was first drilled in 1998 by a team of Russian, French and American scientists. Because the lake is buried so deeply under an Antarctic glacier and is so dark and cold, researchers have surmised it would be an...

Ghost Lake Found Beneath Antarctica's Ice Sheet
2013-07-03 05:32:53

April Flowers for redOrbit.com - Your Universe Online A vast crater has been found in Antarctica's icy surface by the European Space Agency's (ESA) CryoSat satellite. The crater was formed, scientists believe, when a lake lying under about 2 miles of ice drained suddenly. There are lakes of fresh water trapped without a connection to the ocean, deep below the thick ice sheet that covers Antarctica. Scientists who are trying to understand water transport and ice dynamics beneath the...

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...

The Amundsen-Scott South Pole Station is a U.S. research facility based at the South Pole, in Antarctica. It is the southernmost continually inhabited place on the planet. Its name honors Roald Amundsen who reached the South Pole in December 1911, and Robert F. Scott who reached the South Pole in January 1912. The station was constructed in 1956 to support the International Geophysical Year in 1957. It has been continuously occupied since then. It currently lies within 330 feet of the...

Arctic Circle

Arctic Circle -- The Arctic (Land of the Midnight Sun) is the area around the earth's North Pole while antarctic is in South Pole. It includes parts of Russia, Alaska, Canada, Greenland, Lapland and Svalbard as well as the Arctic Ocean. The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone. This is the parallel of...
