WASHINGTON, Aug. 14, 2014 /PRNewswire-USNewswire/ -- A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct research flights Aug. 28 through Oct. 1, covering the peak of summer sea ice melt. http://photos.prnewswire.com/prnvar/20081007/38461LOGO ARISE is NASA's first Arctic airborne campaign designed to take simultaneous measurements...

Snow on top of sea ice
2014-08-14 03:30:55

George Hale, NASA's Goddard Space Flight Center Over the past few decades, Arctic sea ice has been retreating, and although research shows a downward trend in snow on land in the Arctic, long-term measurements of snow depth on sea ice have been less clear. But now, new research using data from NASA's Operation IceBridge shows that snow depth on Arctic sea ice has been decreasing over the past several decades, a trend largely owing to later sea ice freeze-up dates in the Arctic. Arctic...

Finding Deepest Iceberg Scours To Date Provides New Insights Into Arctic’s Glacial Past
2014-08-13 03:02:09

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. The five lineaments, at a depth of 1,200 meters, are the lowest-lying iceberg scours yet to be found on the Arctic sea floor. This finding provides new understanding of the dynamics of the Ice Age and the extent of...

Arctic Melt Ponds

Kate Ramsayer, NASA's Earth Science News Team Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools. On July 16 and July 17, NASA’s ER-2 aircraft flew above Alaskan glaciers and to the North Pole, carrying an instrument called the Multiple Altimeter Beam Experimental Lidar, or MABEL. MABEL is a laser altimeter,...

Hannah Hickey, University of Washington As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the...

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings were published July 22 in The Cryosphere, a journal of the European Geosciences Union (EGU). Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice...

Scientists Tracking Breakup Of Arctic Summer Sea Ice
2014-07-17 03:27:40

By Hannah Hickey, University of Washington As sea ice begins to melt back toward its late September minimum, it is being watched as never before. Scientists have put sensors on and under ice in the Beaufort Sea for an unprecedented campaign to monitor the summer melt. The international effort hopes to figure out the physics of the ice edge in order to better understand and predict open water in Arctic seas. "This has never been done at this level, over such a large area and for such...

redOrbit Staff & Wire Reports - Your Universe Online In less than 100 years, global warming’s impact on the sea ice where emperor penguins breed will result in the loss of at least one-fifth of the species’ population, according to new research appearing in the June 29 edition of the journal Nature Climate Change. There are currently 600,000 emperor penguins living in Antarctica and populations in 45 known colonies are expected to increase slightly by 2050 before declining over...

Antarctic icebergs
2014-06-17 05:19:27

April Flowers for redOrbit.com - Your Universe Online Summer and winter on the Antarctic shore are drastically different. Winters are dark and frozen, while summers are characterized by bright, clear waters, thick with algae and drifting icebergs. Over the last 20 years of warming, however, the region has experienced massive losses of sea ice in the winter that has allowed icebergs to roam freely for most of the year. A new study from the British Antarctic Survey demonstrates how...

Arctic Amplification Has Reduced Risk Of Extreme Cold Weather

redOrbit Staff & Wire Reports - Your Universe Online Despite the fact that many parts of the United States experienced extremely cold conditions this past winter, the risk of such conditions increasing as a result of climate change is unlikely, according to research appearing in the latest edition of Nature Climate Change. Study author Dr. James Screen of the University of Exeter reports that the Arctic amplification phenomenon, which refers to the increased warming rate experienced...

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...
