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...

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...

Antarctica’s Halley VI Now Open For Business
2013-02-05 18:39:33

Lee Rannals for redOrbit.com — Your Universe Online A new scientific research facility in Antarctica has now officially opened, helping to bring a modern twist to adventuring to the most southern part of our world. The Antarctic Research Station has opened 100 years after Captain Robert Falcon Scott's Antarctica expeditions, replacing the 20-year-old Halley V facility. The Halley VI Research Station is the sixth to be built on the floating Brunt Ice Shelf, the first station...

Sea Level Predictions Aided By New Antarctic Geological Timeline
2013-01-16 18:35:25

Alan McStravick for redOrbit.com — Your Universe Online The uncertainty of future sea level rise is getting a little clearer thanks to research being conducted by a team comprised of scientists from the British Antarctic Survey (BAS), the Alfred Wegner Institute for Polar and Marine Research (AWI) and the University of Tromsø. Their study, entitled ℠Grounding-line retreat of the West Antarctic Ice Sheet from inner Pine Island Bay´, is being published in this...

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...

Lee Rannals for redOrbit.com - Your Universe Online Scientists believe they have discovered a hidden rift valley that may be contributing to ice loss in West Antarctica. University of Aberdeen and British Antarctic Survey (BAS) experts made the discovery below Ferrigno Ice Stream, which is a very remote region that has only been visited once before. The team has reveled that the ice-filled ancient rift basin is connected to the warming ocean, which impacts ice flow and loss. The...

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...

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...
