Antarctic Ecosystem Caused Rapid Evolution 041913
2013-04-19 09:39:52

redOrbit Staff & Wire Reports - Your Universe Online The development of the sea-ice ecosystem in the circum-Antarctic Southern Ocean may have triggered further adaptation and evolution of larger organisms such as baleen whales and penguins, according to a new study published Thursday in the journal Science. The area´s ecosystem can be traced back to the emergence of the Antarctic ice sheets some 33.6 million years ago and plays an important role in global marine food webs and...

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...

1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

Antarctic Ice Flow Critical To Health Of The Planet
2013-04-10 10:43:29

April Flowers for redOrbit.com - Your Universe Online "Go with the flow" has been a standard, if somewhat glib, piece of nearly universally applicable advice for a long time — and never more so than now. Shujie Wang, a geography doctoral student at the University of Cincinnati's McMicken College of Arts & Sciences, recently led a team of researchers who discovered that the best way to monitor the environmental health of the Antarctic is just to go with the flow. The ice...

Antarctica's Adelie Penguins May Benefit From Global Warming
2013-04-04 14:02:14

Brett Smith for redOrbit.com - Your Universe Online While some may be lamenting the impending forces of climate change, Adélie penguins could actually benefit from rising global temperatures. According to a new study in the open-access journal PLoS ONE, the Adélie penguin population on Antarctica´s Beaufort Island increased 84 percent as the region´s ice fields retreated from 1958 to 2010. "This research raises new questions about how Antarctic...

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...

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...

Mount Erebus
2014-08-19 09:49:48

Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...

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...
