Ancient Antarctic Ice Melt 66 Feet
2013-07-22 08:50:47

Brett Smith for redOrbit.com - Your Universe Online A large team of international researchers has looked millions of years into the Antarctic past and found evidence that massive sections of the continent's eastern ice sheet once melted to raise sea levels by around 66 feet. "Scientists previously considered the East Antarctic ice sheet to be more stable than the much smaller ice sheets in West Antarctica and Greenland, even though very few studies of East Antarctic ice...

Glass Sponge Community Thrives Despite Antarctic Ice Loss
2013-07-11 18:53:49

Brett Smith for redOrbit.com - Your Universe Online The waters around Antarctica can be an inhospitable place, but a new study has shown that dynamic events in the region are constantly shaping and even boosting the ecosystems in the Southern Ocean. The study, published in Current Biology, reports on a surprisingly prolific community of glass sponges colonizing an area formerly covered by permanent ice - surprising because the sponges live long, slow lives that can extend up to 10,000...

Massive Iceberg Breaks Off Pine Island Glacier In Antarctica
2013-07-10 12:28:33

Brett Smith for redOrbit.com - Your Universe Online One of the Earth's most watched glaciers, Pine Island Glacier (PIG), has released a massive iceberg about eight times the size of Manhattan Island, according to images released by the German Space Agency (DLR). The ice chunk was part of the PIG's ice shelf, which floats on and pushes out into the Southern Ocean for tens of miles. A relatively common occurrence that scientists aren't blaming directly on global warming, similar...

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...

Antarctic King Crabs May Actually Be Native
2013-07-05 05:58:25

Brett Smith for redOrbit.com - Your Universe Online Citing the recent discovery of a major colony of King crabs near Antarctica, some global warming alarmists theorize that rising temperatures have allowed the crabs to claim territory that was previously uninhabitable. According to a new review of crab records published in the journal PLOS ONE, the crabs are not newly established settlers; they've been there all along. The so-called "invasion hypothesis is based on a geographically...

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...

PASADENA, Calif., June 13, 2013 /PRNewswire-USNewswire/ -- Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the sea. But...

Carbon Dioxide Absorption In Antarctic Seas Studied
2013-06-13 09:39:28

Georgia Institute of Technology The seas around Antarctica can, at times, resemble a garden. Large-scale experiments where scientists spray iron into the waters, literally fertilizing phytoplankton, have created huge man-made algal blooms. Such geoengineering experiments produce diatoms, which pull carbon dioxide out of the air. Experts argue that this practice can help offset Earth´s rising carbon dioxide levels. However, the experiments are controversial and, according to a new...

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...

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...
