Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor. The research by scientists at UNSW and the Australian Antarctic Division predicts that biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm. The study, Light-driven tipping points in polar ecosystems, will be published in the journal...

Polar Pool Not Extreme
2013-07-31 11:23:48

Brett Smith for redOrbit.com - Your Universe Online Last week, pictures from the North Pole Experimental Observatory (NPEO) showed the North Pole seemingly covered by a sea of water, but according to a statement from the project's principal investigator, conditions in the Arctic are typical for this time of year and viewing the images is all a matter of perspective. "Every summer when the sun melts the surface the water has to go someplace, so it accumulates in these ponds," said Jamie...

Arctic Winters Were Ice-Free Three To Five Million Years Ago
2013-07-30 06:29:43

April Flowers for redOrbit.com - Your Universe Online During the Pliocene Epoch, the Earth was substantially warmer than it is today, despite similar concentrations of carbon dioxide in the atmosphere. A new study, led by the University of Colorado Boulder, suggests year-round ice-free conditions across the surface of the Arctic Ocean could explain the difference. The study was published in a recent issue of Palaeogeography, Paleoclimatology, Palaeoecology. A new record was marked by...

New research by UM bioclimatology Assistant Professor Ashley Ballantyne models the influence of Arctic sea ice on Arctic temperatures during the Pliocene era. His research was published in the Research Highlight section of the July issue of Nature Geoscience. The full paper will be published in Palaeogeography, Palaeoclimatology, Palaeoecology: An International Journal for the Geosciences. Ballantyne and coauthors from Northwestern University, the University of Colorado and the National...

Fund recommended to hedge against greatest threat: a breached oil sands tailing pond; Biodiversity in watershed covering roughly 20% of Canada compared to Africa's Serengeti; Alarm raised at melting of permafrost, ice that plays vital global climate role Canada's Mackenzie River basin -- among the world's most important major ecosystems -- is poorly studied, inadequately monitored, and at serious risk due to climate change and resource exploitation, a panel of international scientists warn...

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice extent in the satellite era, on atmospheric circulation and surface temperatures. Two 30-year simulations, one using the sea ice levels of 2007 and another using sea ice levels at the end of the 20th...

NASA's Arctic IceBridge Campaign Closes With Much Success
2013-04-30 14:14:59

Lee Rannals for redOrbit.com — Your Universe Online NASA said its Operation IceBridge team has finished up another successful campaign to continue collecting data of Arctic ice measurements. IceBridge was started in 2009 to help continue and expand a dataset started by NASA's Ice, Cloud and Land Elevation Satellite (ICESat) in 2003. During this year's campaign, the team measured sea ice, mapped sub-ice bedrock and gathered data on Greenland's glaciers by flying science missions...

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...

Researchers Predict Sea Ice-Free Arctic Summers By 2050
2013-04-13 08:18:46

April Flowers for redOrbit.com — Your Universe Online The question of ice-free summers in the Arctic, for most scientists, is not "if," but "when." A new study by two National Oceanic and Atmospheric Administration (NOAA) scientists says that "when" is coming sooner than many thought. Already, the Arctic has experienced a loss of thick, multi-year ice, with last September´s extent being less than half the average of 1979-2000. The scientists, James Overland...

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
