Proposal follows first continent-wide survey of Antarctic biogeography An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

Continuing Deep Ocean Change In The Southern Ocean
2012-05-22 03:53:13

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

Antarctic Octopus Provides Clues To Ice Sheet Collapse
2012-05-10 08:34:34

Brett Smith for Redorbit.com A joint team of UK and Australian researchers has found that two separate groups of Antarctic octopuses, from the Ross and Weddell seas on different sides of the continent, are almost genetically identical. This suggests that the two seas, which are now separated by the West Antarctic Ice Sheet, were once joined together, possibly a result of the partial collapse of the continental ice sheet. Researchers analyzed the genes of 450 Turquet's octopuses...

Researchers Track Emperor Penguins From Space
2012-04-15 03:39:04

Thanks to new technology, a study reveals there to be twice as many emperor penguins in Antarctica than had previously been estimated. The study will be used as a benchmark to understand the effects climate change is having on these flightless birds. Published this week in the journal PLoS ONE, an international team of scientists reports how they used a Very High Resolution (VHR) satellite images to estimate the size of the emperor penguin communities. In order to distinguish the birds...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

First-ever Use Of Airborne Resistivity System In Antarctica Allows Researchers To Look Beneath Surface In Untapped Territories
2012-03-24 03:01:55

NSF partners with international team to gather new information on hidden environments and past climate conditions in Antarctica National Science Foundation- (NSF) funded researchers have successfully tested equipment to map the hidden distribution of groundwater and ice in the McMurdo Dry Valleys region for the first time in Antarctica. The mapping technique, an airborne electrical resistivity instrument, will enable researchers to study microbial ecosystems in sub-glacial environments....

Endangered Antarctic Blue Whales Show Surprising Genetic Diversity
2012-03-09 03:30:09

More than 99 percent of Antarctic blue whales were killed by commercial whalers during the 20th century, but the first circumpolar genetic study of these critically endangered whales has found a surprisingly high level of diversity among the surviving population of some 2,200 individuals. That, says lead author Angela Sremba of Oregon State University, may bode well for their future recovery. Results of the study have just been published in the open-access journal, PLoS ONE. As part of...

Invasive Species Put Antarctic Natives At Risk
2012-03-06 11:15:04

As temperatures warm along Antarctica´s outer fringes, it allows for invasive plants and organisms to be carried in inadvertently by visiting scientists and tourists, putting the pristine ecosystem at risk, researchers have found. An international team of researchers, writing in the Proceedings of the National Academy of Sciences (PNAS), said they scoured the clothes and boots of those visiting the southernmost continent and found that most were carrying plant seeds. The risks from...

In a modern iteration of the great age of Antarctic exploration of the 19th and 20th centuries, three teams of scientists are rushing to reach not the South Pole like Roald Amundsen, Robert Falcon Scott and Ernest Shackleton, but lakes deep below the surface of the Frozen Continent believed to hold scientific treasures. That quest by Russian, British and American scientific teams for water samples is the topic of an article in the current edition of Chemical & Engineering News, the weekly...

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

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...
