Arctic Ice Improving
2013-12-16 15:27:28

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) CryoSat satellite has delivered some good news about the Arctic sea ice this fall. New measurements taken by CryoSat show the volume of Arctic sea ice has significantly increased this fall, rising by about 50 percent compared to last year. Satellites have been showing a downward trend in the area of Arctic Ocean covered by ice over the past few decades, so the latest measurements are much welcomed news....

Extreme Summer Weather May Be Caused By Ice Loss In The Arctic
2013-12-09 11:16:06

redOrbit Staff & Wire Reports - Your Universe Online The cause of increasingly intense summer heat waves and downpours throughout the US and Europe could be due to thawing Arctic ice and snow, according to new research published Sunday in the journal Nature Climate Change. In the study, researchers from the Chinese Academy of Sciences and the Rutgers University Institute of Marine and Coastal Sciences looked at satellite observations of snow cover and sea-ice extent during the...

The Health Of Antarctic Glaciers Relies On Salt Intake: NASA
2013-12-06 10:19:26

April Flowers for redOrbit.com - Your Universe Online An intriguing link between sea ice conditions and the melting rate of Totten Glacier, the glacier in East Antarctica that discharges the most ice into the ocean, has been found by a NASA-led study. The discovery, published in Nature Communications, involves cold, extra salty water—brine—that forms within openings in sea ice. The findings will add to our understanding of how ice sheets interact with the ocean, and may improve our...

Algae Reveal History Of Arctic Sea Ice
2013-11-19 12:15:57

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has developed a novel method for tracking changes in Arctic sea ice through the analysis of growth layers of seafloor algae, according to their report in the Proceedings of the National Academy of Sciences. The study found that the algae Clathromorphum compactum accumulates a calcite crust as it grows and changes to this crust over time can be analyzed to reveal historical conditions of the...

WASHINGTON, Oct. 31, 2013 /PRNewswire-USNewswire/ -- For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) NASA's C-130 research aircraft flew from the Wallops Flight Facility in Wallops Island, Va., to Greenland Wednesday where they will conduct survey flights to collect data that will improve...

Retreating Arctic Ice To Blame For Bad British Weather
2013-10-29 11:43:24

Brett Smith for redOrbit.com - Your Universe Online Britons never seem to get a break from bad weather, and now one scientist believes he may have found a culprit to point the finger at: retreating Arctic sea ice. According to a new study from the University of Exeter’s James Screen that was published in the journal Environmental Research Letters, the run of wet summers that hit northwest Europe between 2007 and 2012 was partially due to the loss of Arctic sea ice that shifted the jet...

Climate Change May Be Indirectly Threatening Caribou In The Arctic
2013-10-01 14:04:59

Lee Rannals for redOrbit.com - Your Universe Online New research indicates that caribou may be indirectly affected by climate change due to sea-ice loss in the Arctic. Researchers, publishing a paper in the journal Nature Communications, say that melting sea ice is leading to fewer caribou calf births and higher calf mortality in Greenland. The team was able to link the melting Arctic sea ice with changes in the timing of plant growth on land, which in turn led to lower production of...

Arctic Sea Ice Minimum For 2013 Sixth Lowest On Record
2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

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...

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...
