Russian, Chinese Ships Escape Death Throes Of Southern Ocean Ice
2014-01-07 09:45:02

redOrbit Staff & Wire Reports - Your Universe Online UPDATE: January 7, 2014 @ 9:45 a.m. Two ships that had been stranded in a sea of ice in the Southern Ocean, one since Christmas Eve, have broken free. The passengers of the Russian research vessel Akademik Shokalskiy were rescued on January 2 by helicopter from Chinese icebreaker Xue Long. However, that ship also got stuck in the sea ice the following day. The rescued passengers were safely boarded onto an Australian ship...

Antarctic Heritage Trust Finds Lost Shackleton Expedition Photos
2013-12-30 07:25:44

redOrbit Staff & Wire Reports – Your Universe Online Undeveloped photos taken during one leg of Ernest Shackleton's Imperial Trans-Antarctic Expedition have been discovered in the hut of another polar region explorer, various media outlets reported on Sunday. According to CNN’s Ralph Ellis, the negatives were discovered in an expedition hut used by British explorer Capt. Robert Falcon Scott during his unsuccessful 1912 attempt to become the first man to reach the South Pole....

Diamonds  On Antarctica
2013-12-17 15:37:20

[ Watch the Video: Traces Of Diamonds Found In Antarctica ] Brett Smith for redOrbit.com - Your Universe Online Researchers working in Antarctica have announced the discovery of kimberlite deposits on the frozen continent. Kimberlites are rocks known for their propensity to contain diamonds. The discovery is not expected to set off a diamond rush anytime soon, however, as an international treaty has banned mining on Antarctica until 2041. However, it does make a potential extension...

East Antarctica Is Pushing Around Its Softer-Mantled Western Half
2013-12-12 07:51:20

April Flowers for redOrbit.com - Your Universe Online It's easy to know what to do when half-siblings are pushing each other around, but what do you do about half-continents? A team of researchers, led by Ohio State University, have discovered that East Antarctica is pushing West Antarctica around. West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East...

ESA CryoSat Mission Confirms Antarctic Ice Loss Is On The Rise
2013-12-12 06:08:21

Alan McStravick for redOrbit.com - Your Universe Online With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica. This environmental faux pas directly affects the estimates on global sea level rise as well. The team presenting these findings conducted their research with the Natural Environment Research Council’s Center for...

Antarctic High Ridge Gets Distinction As Coldest Place On Earth
2013-12-10 09:03:50

[ Watch the Video: Coldest Place On Earth Is The East Antarctic Plateau ] redOrbit Staff & Wire Reports - Your Universe Online If you think it’s cold where you live, consider this: NASA satellites have just discovered the chilliest place on Earth, where temperatures can plummet to minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius). This “glad I don’t live there” location is a high ridge in Antarctica on the East Antarctic Plateau, where temperatures in several...

WASHINGTON, Dec. 9, 2013 /PRNewswire-USNewswire/ -- What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists made the discovery while analyzing the most detailed global surface temperature maps to date, developed with data from remote...

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...

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...

Cryolophosaurus, meaning "cold crest lizard", is a genus of theropod dinosaur from the Early Jurassic Period (Pliensbachian Age). It is known from the Hanson Formation (previously known as the Upper Falla Formation). It was discovered by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica. It was also the first dinosaur from Antarctica to be officially named. Dr. William Hammer and his team unearthed the dinosaur during the...
