The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study. The discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Scientists Find Rapid Warming Threatens Rich Seafloor Communities
2013-12-04 10:09:25

University of Hawaii at Manoa Deep inside the dramatic subpolar fjords of Antarctica, researchers from the University of Hawai'i at Mānoa have discovered an unexpected abundance and diversity at the seafloor. During a recent expedition, UH scientists for the first time studied the seafloor communities of glacier dominated fjords along the west Antarctic Peninsula, a region undergoing very rapid climate warming. The scientists expected to find impoverished seafloor communities highly...

Airborne Radar Looks Through Thick Ice During NASA Polar Campaigns
2013-12-03 15:23:42

NASA The bedrock hidden beneath the thick ice sheets covering Greenland and Antarctica has intrigued researchers for years. Scientists are interested in how the shape of this hidden terrain affects how ice moves -- a key factor in making predictions about the future of these massive ice reservoirs and their contribution to sea level rise in a changing climate. NASA has been monitoring Antarctic and Arctic ice since 2009 with the Operation IceBridge airborne mission. Although the primary...

Greenland Ice Sheet Is Hiding Subglacial Lakes
2013-11-28 04:29:14

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a pair of subglacial lakes discovered over 800 meters beneath the Greenland Ice Sheet – the first ever to be discovered in the island nation, according to research appearing in the latest edition of the journal Geophysical Research Letters. The two lakes are reportedly between eight and 10 square kilometers in surface area, but might have been up to three times larger than their current size at one...

Brooding Marine Worm Found In Antarctica
2013-11-27 16:10:40

University of Barcelona Brooding is a usual behavior in animals. However, to observe it in a marine worm is exceptional and, more surprisingly, it guards eggs from external threats. The scientific finding, published recently in the journal Polar Biology, was developed by researchers Conxita Àvila and Sergio Taboada, from the Department of Animal Biology of the University of Barcelona (UB) and members of the Institute of Research in Biodiversity (IRBio); Juan Junoy, from the University of...

IceBridge P-3 Lands Safely At McMurdo
2013-11-26 11:33:48

[ Watch The Video: First Landing: IceBridge P-3 on the Sea Ice Runway ] NASA Making the current NASA Operation IceBridge campaign – the first to ever operate directly from Antarctica – a reality took a year and a half of planning and coordination, finishing with weeks of intense work both at home and in Antarctica. Before anything at all could happen, the mission's science team had to come up with science flight plans. And mission planners worked closely with the National...

Volcano Found Deep Below West Antarctica's Ice
2013-11-18 04:31:37

[ Watch the Video: Volcano Found In Western Antarctica ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Washington University in St. Louis have discovered a volcano located beneath roughly one kilometer of ice in western Antarctica, and they believe that the heat it produces could increase the rate of ice loss from one of the region’s primary ice streams. In January 2010, a team of investigators, led by professor of earth and planetary science...

Operation IceBridge 2013 Campaign Begins At McMurdo Station
2013-11-17 05:02:11

redOrbit Staff & Wire Reports - Your Universe Online The arrival of NASA scientists and aircraft at McMurdo Station in Antarctica on Saturday marks the beginning of the 2013 Operation IceBridge field campaign in that region, the US space agency has announced. As part of the mission, daily survey flights will take place through November 26 on a NASA P-3 research aircraft departing from a base of operations at the National Science Foundation (NSF) facility. Researchers traveling on...

Mount Erebus
2014-08-19 09:49:48

Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...

Antarctica

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...

Ross Seal, Ommatophoca rossii
2013-01-01 15:44:30

The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...

Weddell Seal, Leptonychotes weddellii
2012-06-27 21:35:24

The Weddell seal (Leptonychotes weddellii) is a large true seal in the Lobodontini tribe. It is native to Antarctica, with its range consisting of a large “ring” that surrounds Antarctica. This seal will spend most of its time in the water instead of on land. The Weddell seal appears on the IUCN Red List with a conservation status of “Least Concern”.  It is estimated this seal numbers over 800,000 individuals in the wild. First discovered in 1820s by a British sealing captain...

Antarctic Silverfish, Pleuragramma antarcticum
2012-04-02 17:14:35

The Antarctic Silverfish, (Pleuragramma antarcticum), is a member of the Notothenioidei family of fish. It is widely distributed around the Antarctic, but has largely disappeared from the western side of the northern Antarctic Peninsula based on 2010 research funded by the National Science Foundation. It is also found throughout the Southern Ocean. It grows to an average size of 6 inches, but has been known to reach lengths of up to 10 inches. It is usually pink with a silver tint, and...
