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...

Scientists Find Bacteria Discovery In Antarctic Lake Was A Contaminant
2013-03-11 12:32:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Last Friday (Mar 8) headlines popped up everywhere reporting that Russian scientists had found initial evidence of a new bacterial life form pulled up from the depths of Antarctica´s largest subglacial body of water, Lake Vostok. The discovery was viewed as extraordinary, and may have sealed the deal for Russia becoming the first country to discover a new species of bacteria in such an extreme location. However, new claims...

New Bacteria Discovered In Samples From Antarctica's Lake Vostok
2013-03-08 12:21:54

Lawrence LeBlond for redOrbit.com - Your Universe Online Samples taken from an underground lake in Antarctica last January contain a new life form previously unknown to science, according to researchers who are in charge of studying the returned samples. The team said they have discovered a bacterium that has been sealed off for more than a million years in the depths of what is now known as Lake Vostok. The scientists, led by Sergei Bulat of the genetics laboratory at the Saint...

The Forming Of Antarctica's Hidden Fjords
2013-03-06 13:41:41

University of Arizona Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. Although radar surveys have revealed a rugged alpine landscape...

Autonomous Machine Makes Over-ice Travel Safer
2013-03-04 11:09:54

National Science Foundation A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot--dubbed Yeti--could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could...

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
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...

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...
