A new paper co-written by UM associate professor Mark Hebblewhite details ecological changes caused by a loss of Arctic sea ice. The paper concludes that the loss of sea ice obviously will impact the marine food web and the marine mammals that depend on sea ice habitat. Other major ecological changes in adjacent land-based habitats and species also will occur because of warming oceans. The findings were published in the Aug. 2 issue of Science magazine. Wildlife species like the polar...

Wildlife Greatly Impacted By Arctic Sea-Ice Loss

April Flowers for redOrbit.com - Your Universe Online Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades. An international team of scientists, led by Penn State University biologist Eric Post, examined relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus, as...

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...

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...
