Global Warming Could Explain Exponential Sea Ice Growth
2013-09-18 12:28:55

Michael Harper for redOrbit.com - Your Universe Online In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National...

New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas. Iceberg production and melting causes 2,800 cubic kilometers of ice to leave the Antarctic ice sheet every year. Most of this is replaced by snowfall but any imbalance contributes to a change in global sea level. For many decades, experts have believed that the most important process...

ESA’s CryoSat Mission Provides New Insights Into Our Fragile Polar Regions
2013-09-11 11:48:06

[ Watch The Video - Arctic Ice Thickness 2010 to 2013 ] ESA Offering new insights into our fragile polar regions, ESA’s CryoSat mission has provided three consecutive years of Arctic sea-ice thickness measurements, which show that the ice continues to thin. Although satellites have witnessed a downward trend in the extent of sea ice over the last two decades, it is essential to have accurate information on the mass or volume of ice being lost. This is a more accurate measure of the...

Important Role In Polar Ocean Carbon Budgets Played By Micro-gels From Tiny Arctic And Antarctic Ice Algae
2013-09-10 10:47:21

Aarhus University Secretion of polysaccharides from the micro community living within the sea ice stick organism together and forms greater particles introducing a rapid transport of carbon to the seafloor. New research now makes it possible to forecast the importance for the global carbon budget of this transport. A community of microscopic algae and bacteria thrives within the Arctic and Antarctic pack ice. These ice-organisms are adapted to growing on the ice crystal surfaces and...

Arctic Sea Ice Political Controversy
2013-09-09 10:50:24

Brett Smith for redOrbit.com - Your Universe Online Instead of providing a sneak-peek into cutting-edge climate research, a recently leaked UN report on Arctic sea ice has mostly provided insight into the political divide surrounding the contentious issue of global warming. Two of the UK’s supposedly more conservative periodicals, the Daily Mail and The Telegraph, seized on the leaked report’s finding that Arctic sea ice was 60 percent larger in August 2013 compared to August 2012....

2013 Ice Melt Will Not Be Record Year Despite Continuing Downhill Trends
2013-08-23 10:06:14

[WATCH VIDEO: Summer Arctic Ice Retreat 2013] Lee Rannals for redOrbit.com - Your Universe Online Arctic sea ice is reaching its annual "minimum" melt for the summer, but NASA says this year's low will unlikely be breaking any records. Last year, Arctic sea ice melted to a record low, making it the largest summer melt since satellites began measuring the process in 1979. This year's melt is beginning to reach its minimum now, and even though it’s not going to catch any records,...

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
2013-08-02 07:11:40

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...

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...

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...

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...
