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....

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...

Moss And Microbes Reveal Unprecedented Ecological Change On Warming Antarctic Peninsula
2013-08-29 13:21:21

Cell Press By carefully analyzing a 150-year-old moss bank on the Antarctic Peninsula, researchers reporting in Current Biology, a Cell Press publication, on August 29 describe an unprecedented rate of ecological change since the 1960s driven by warming temperatures. "Whilst moss and amoebae may not be the first organisms that come to mind when considering Antarctica, they are dominant components of the year-round terrestrial ecosystem in the small ice-free zones during an austral...

Glacier Geometry Linked To Diverse Calving Patterns
2013-07-23 05:24:37

April Flowers for redOrbit.com - Your Universe Online Large stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean in events over the coming decades that could aggravate sea level rise. The new study, published in Nature Geoscience, describes new iceberg calving simulations from the University of Michigan. "If this starts to happen and we're right, we might be closer to the higher end of sea level rise estimates for...

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 Ice Shelf Collapse Has Been Occurring For 600 Years, Manmade Climate Change Is Now Adding To Problem
2012-08-23 10:53:35

Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...

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...

Antarctica Ice Sheet May Begin Melting Rapidly By Century's End
2012-05-09 13:58:16

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century. The finding, made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, refute a widely believed theory that ice shelves in the Weddell Sea would not be affected by global warming due to the peripheral location of the sea. "The Weddell Sea was not really on the screen because we all thought that unlike the Amundsen...

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...
