Antarctic Sea Ice Reached New Record High Extent This Year
2014-10-10 03:41:14

[ Watch The Video: The Arctic And The Antarctic Respond In Opposite Ways ] Provided by Kate Ramsayer, NASA Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice...

Antifreeze Proteins Prevent Freezing And Melting For Antarctic Fish
2014-09-24 03:04:19

University of Illinois at Urbana-Champaign Antarctic fish that manufacture their own "antifreeze" proteins to survive in the icy Southern Ocean also suffer an unfortunate side effect, researchers report: The protein-bound ice crystals that accumulate inside their bodies resist melting even when temperatures warm. The finding is reported in the Proceedings of the National Academy of Sciences. "We discovered what appears to be an undesirable consequence of the evolution of antifreeze...

rising antartic sea level
2014-09-01 05:17:20

Chuck Bednar for redOrbit.com - Your Universe Online The sea level around the coast of Antarctica is expected to rise faster than the projected global rate, experts from the University of Southampton report in research appearing Sunday in the advanced online edition of the journal Nature Geoscience. In the paper, lead author Craig Rye and colleagues from the National Oceanography Centre, the British Antarctic Survey and the Scottish Association for Marine Science explain that satellite...

redOrbit Staff & Wire Reports - Your Universe Online An international team of biologists has discovered living microbes and an active ecosystem located one-half mile beneath the surface of the West Antarctic Ice Sheet, according to new research published online Wednesday in the journal Nature. The study, which was funded by the National Science Foundation (NSF) and led by Montana State University professor John Priscu, collected samples from subglacial Lake Whillans, which is...

redOrbit Staff & Wire Reports - Your Universe Online Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution. In research appearing in Monday’s edition of the Nature journal Scientific Reports, Joe McConnell of Nevada's Desert Research Institute (DRI) and his colleagues explain how data from 16 ice cores collected...

antarctic sea ice extent
2014-07-23 02:00:24

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings were published July 22 in The Cryosphere, a journal of the European Geosciences Union (EGU). Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice...

Better Protection From Humans Needed For Antarctica's Ice-Free Land
2014-06-19 06:55:51

April Flowers for redOrbit.com - Your Universe Online Despite the harsh conditions, the number of visitors arriving in the Antarctic is soaring each year. This worries the world's leading environmental scientists who say that Antarctica's ice-free land needs better protection from human activities. Of the 55 Antarctic areas designated for protection, all of them lie close to human activity sites and seven are at a high risk for biological invasions. According to the study, published in...

Melting Arctic Sea Ice Opens New Passages For Invasive Species
2014-05-28 03:24:06

Smithsonian Scientists say early action could protect coasts For the first time in roughly 2 million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave both coasts and Arctic waters vulnerable to a large wave of invasive species, biologists from the Smithsonian Environmental Research Center assert in a commentary published May 28 in Nature Climate Change. Two new shipping routes have opened in the Arctic: the...

Ice Mission And Harsh Polar Camping
2014-05-16 03:57:04

ESA While camping may appeal to some, scientists recently took the pastime to punishing limits. Enduring the bitter Arctic cold out on the sea ice, they were part of a major international effort to ensure ESA’s CryoSat satellite is delivering a true picture of Earth’s changing ice. Considered a barometer of climate change, diminishing polar ice has been a hot topic for a number of years. Over the last few decades, satellites have shown a downward trend in the area of Arctic Ocean...

WHOI's Nereus remotely operated vehicle
2014-05-12 05:07:47

Woods Hole Oceanographic Institution (WHOI) Scientists think Nereus imploded exploring the Kermadec Trench On Saturday, May 10, 2014, at 2 p.m. local time (10 p.m. Friday EDT), the hybrid remotely operated vehicle Nereus was confirmed lost at 9,990 meters (6.2 miles) depth in the Kermadec Trench northeast of New Zealand. The unmanned vehicle was working as part of a mission to explore the ocean's hadal region from 6,000 to nearly 11,000 meters deep. Scientists say a portion of it likely...

Antarctica
2013-02-18 10:15:24

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
2004-10-19 04:45:44

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...
