Study Reveals Links Between Antarctic Climate And Food Chain
2014-07-08 03:24:51

By David Malmquist, Virginia Institute of Marine Science A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins. The study, published in today’s issue of Nature Communications, is authored by Dr. Grace Saba, an alumna of William & Mary’s Virginia...

Gentoo penguins
2014-06-13 07:30:18

Gerard LeBlond for redOrbit.com - Your Universe Online The penguin population from the last ice age to about 1,000 years ago has been on an up and down trend. However, due to a warming climate and retracting ice, certain penguin populations have steadily declined, according to a recent paper which was published in the journal Scientific Reports. The team of scientists from the Universities of Southampton and Oxford used a genetic technique to estimate penguin populations of the past....

Massive Iceberg Could Disrupt Shipping Lanes In The Southern Ocean
2014-04-23 08:56:59

Lawrence LeBlond for redOrbit.com - Your Universe Online An iceberg previously said to be more than eight times the size of Manhattan could soon disrupt shipping lanes as it moves well outside of Pine Island Bay in Antarctica. The iceberg (called B31), which broke off from Pine Island Glacier in November 2013, is now drifting out of the bay and into the Amundsen Sea off Antarctica’s western banks. Now said to be twice the size of Atlanta (six times the size of Manhattan), B31 will...

How Would You Like To Work At Concordia Research Station In Antarctica?
2014-04-17 09:23:47

ESA Are you a team player who is unafraid of long isolation? Do you have a medical degree and a healthy love of extremes? ESA is offering the chance of a lifetime to run space experiments in one of the world’s most isolated places: Concordia research station in Antarctica. Lying 1600 km from the South Pole in the Antarctic desert, Concordia was built on a plateau 3200 m up. Its location means that its inhabitants are pushed to their limits. Outside temperatures of –80°C...

Disappearing Snow Increases Risk Of Ice Shelves Collapsing  In Antarctica
2014-01-30 08:19:42

British Antarctic Survey Sea-level research in Antarctica A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises. A rapid reduction of greenhouse gas emissions could save a number of these ice shelves, researchers at Utrecht University and the British Antarctic Survey say in a new...

Iceberg Breaks Off Pine Island Glacier, May Disrupt Shipping Lanes
2013-11-14 15:21:30

Lee Rannals for redOrbit.com - Your Universe Online Researchers from the University of Sheffield and Southampton were awarded an emergency grant to study how an iceberg that recently separated from an Antarctic glacier could disrupt shipping lanes. Scientists were given $80,000 to fund a six-month study that will predict the movements of a 270-square-mile iceberg that began drifting away from Pine Island Glacier in Antarctica back in July. A NASA image (above) taken by the Aqua...

Massive Iceberg Breaks Off Pine Island Glacier In Antarctica
2013-07-10 12:28:33

Brett Smith for redOrbit.com - Your Universe Online One of the Earth's most watched glaciers, Pine Island Glacier (PIG), has released a massive iceberg about eight times the size of Manhattan Island, according to images released by the German Space Agency (DLR). The ice chunk was part of the PIG's ice shelf, which floats on and pushes out into the Southern Ocean for tens of miles. A relatively common occurrence that scientists aren't blaming directly on global warming, similar...

Antarctica's Salty Don Juan Pond Offers Watery Hope For Mars
2013-02-07 15:42:19

Lawrence LeBlond for redOrbit.com - Your Universe Online Several bodies of water around the world are known for their salty content. Among the most well-known are the Great Salt Lake in Utah and the Dead Sea. But these bodies of water pale in comparison to Don Juan Pond in Antarctica, known as the saltiest body of water on Earth. The pond, situated in the McMurdo Dry Valleys of the harsh, icy continent, keeps from freezing because of its salt-rich composition. But why this landlocked...

Three Canadians Believed To Have Crashed In Antarctic Mountains, Rescue Delayed Due To Bad Weather
2013-01-24 08:21:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Three Canadians who were aboard a small plane flying over the Antarctic are presumably missing after an emergency locator started transmitting a signal Wednesday night. Matters were complicated when bad weather forced a search and rescue mission to go on hold. The flight was going from the US-operated McMurdo Station near the South Pole to Zucchelli Station, an Italian research base in Terra Nova Bay. The emergency locator began...

Areas of Bendable Ice Help Support Antarctic Ice Shelf
2012-12-09 06:42:36

redOrbit Staff & Wire Reports - Your Universe Online The largest remaining Antarctic ice shelf contains several cracks and crevasses that could make it prone to collapse, but also areas in which different types of frozen water blend together to create areas of bendable ice that help hold it together, according to a new study presented late last week. Experts at the University of Colorado, Boulder's Cooperative Institute for Research in the Environmental Sciences (CIRES) discovered...

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...

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...
