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...

Basal Melt Responsible For Antarctic Ice Shelf Loss
2013-06-14 06:20:18

redOrbit Staff & Wire Reports - Your Universe Online The majority of Antarctica´s ice loss is caused by warm ocean waters eating away at the undersides of ice shelves, not the sudden release and breaking away of ice masses from glaciers (a process known as calving), according to new research appearing in Friday´s edition of the journal Science. In what is being called “the first comprehensive survey of all Antarctic ice shelves,” researchers from the University...

NASA's Operation IceBridge Mission Contributes To New Map Of Antarctica
2013-06-06 09:26:57

NASA A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data–known as Bedmap–that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation...

Organisms In 33.6 Million Year Old Ice Pack Evolved To Survive
2013-05-28 09:17:24

Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers publishing a paper in the latest issue of the journal Science have found through Antarctic planktonic ice core examinations that the continental ice cap formed more than 33 million years ago. Scientists from the Andalusian Institute of Earth Sciences (IACT), a joint collaboration between the University of Granada and the Spanish National Research Council (CSIC), said the seasonal primary productivity of planktonic...

For Antarctic Clams Age Matters
2013-04-19 09:03:56

April Flowers for redOrbit.com - Your Universe Online According to a new study from the British Antarctic Survey (BAS), the University of Kiel, and the Alfred Wegener Institute, age matters for Antarctic clams when it comes to adapting to the effects of climate change. The study, published in the journal Global Change Biology, provides new insights into the likely impact that predicted environmental change could have on the future of ocean biodiversity. The Antarctic clam (laturnula...

New Chart Shows Entire Topography Of Antarctic Seafloor In Detail
2013-04-09 15:10:20

Alfred Wegener Institute for Polar and Marine Research Reliable information on the depth and floor structure of the Southern Ocean has so far been available for only few coastal regions of the Antarctic. An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first time succeeded in creating a digital map of the entire Antarctic seafloor. The International Bathymetric Chart of the Southern Ocean...

Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

NSF Issues Response To Recommendations For Streamlining Scientific Logistics In Antarctica
2013-03-22 11:34:46

National Science Foundation Focus is on cost-effective and efficient ways to support Antarctic science as research frontiers evolve The National Science Foundation (NSF) has issued a summary response to the recommendations of an external panel of experts that was charged with advising the agency on how to improve and streamline its logistical capabilities to more efficiently support world-class Antarctic science in coming decades. The NSF document, which was made public on March 21,...

Different Genetic Mechanisms Used By Antarctic and Arctic Insects To Cope With Lack of Water
2013-03-13 08:00:08

National Science Foundation Although they live in similarly extreme ecosystems at opposite ends of the world, Antarctic insects appear to employ entirely different methods at the genetic level to cope with extremely dry conditions than their counterparts that live north of the Arctic Circle, according to National Science Foundation- (NSF) funded researchers. Writing in the Proceedings of the National Academy of Sciences, the researchers concluded, "Polar arthropods have developed...

Antarctic Minke Whale, Balaenoptera bonaerensis
2013-06-22 16:21:07

The Antarctic minke whale (Balaenoptera bonaerensis), also known as the southern minke whale, is one of two minke whales within the Mysticeti suborder, which contains baleen and rorqual whales. It can be found in every ocean in the southern hemisphere, residing in Antarctic waters in the summer months and northern waters in the winter months, where its range overlaps that the smaller common minke whale. The Antarctic minke whale was once classified with the common minke whale as a single...

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...

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...

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
