Latest Sea ice Stories
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.
A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate.
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.
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.
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.
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.
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.
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.
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.
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.
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...
