WASHINGTON, Sept. 16, 2014 /PRNewswire-USNewswire/ -- Over the past few decades, average global temperatures have been on the rise, and this warming is happening two to three times faster in the Arctic. As the region's summer comes to a close, NASA is hard at work studying how rising temperatures are affecting the Arctic. http://photos.prnewswire.com/prnvar/20081007/38461LOGO NASA researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed...

Maria-José Viñas, NASA’s Earth Science News Team One of the most visible signs of climate change in recent years was not even visible at all until a few decades ago. The sea ice cap that covers the Arctic Ocean has been changing dramatically, especially in the last 15 years. Its ice is thinner and more vulnerable – and at its summer minimum now covers more than 1 million fewer square miles than in the late 1970s. That’s enough missing ice to cover Alaska, California and Texas....

Chuck Bednar for redOrbit.com - Your Universe Online The sea level around the coast of Antarctica is expected to rise faster than the projected global rate, experts from the University of Southampton report in research appearing Sunday in the advanced online edition of the journal Nature Geoscience. In the paper, lead author Craig Rye and colleagues from the National Oceanography Centre, the British Antarctic Survey and the Scottish Association for Marine Science explain that satellite...

Patrick Lynch, NASA’s Earth Science News Team As we near the final month of summer in the Northern Hemisphere, NASA scientists are watching the annual seasonal melting of the Arctic sea ice cover. The floating, frozen cap that stretches across the Arctic Ocean shrinks throughout summer until beginning to regrow, typically around mid-September. As of Aug. 19, Arctic sea ice covered about 2.31 million square miles. While this is on track to be larger than the record-breaking low year in...

Climate Impacts Of Arctic Sea Ice Loss To Be Investigated By NASA

[ Watch The Video: NASA’s ARISE Arctic Mission Takes Shape ] Steve Cole, NASA 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. ARISE is NASA's first Arctic airborne campaign designed to take simultaneous measurements of ice, clouds and the...

Snow on top of sea ice

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

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...

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...
