The National Oceanic and Atmospheric Administration (NOAA) proposed on Friday to list six types of seals as "threatened" under the Endangered Species Act because they face hardships due to disappearing sea ice and melting snow packs. The NOAA said that four types of ringed seals that live in the Arctic basin and North Atlantic as well as two populations of bearded seals in the Pacific Ocean should be listed as threatened. The Saimaa ringed seals in Finland are already recognized as...

A NASA analysis of satellite data has quantified, for the first time, the amount of older and thicker "multiyear" sea ice lost from the Arctic Ocean due to melting. Since the start of the satellite record in 1979, scientists have observed the continued disappearance of older "multiyear" sea ice that survives more than one summer melt season. Some scientists suspected that this loss was due entirely to wind pushing the ice out of the Arctic Basin -- a process that scientists refer to as...

Proof-of-Concept Study Published in Journal of Geophysical Research-Oceans In a research paper published online Saturday in the Journal of Geophysical Research Oceans, a publication of the American Geological Union (AGU), scientists reported the southern Baffin Bay off West Greenland has continued warming since wintertime ocean temperatures were last effectively measured there in the early 2000s. Temperatures in the study were collected by narwhals, medium-sized toothed Arctic whales, during...

Climate scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA) reported Thursday that Arctic temperatures are on the rise again. The sea ice extent has also fallen to one of the lowest levels on record, according to NOAA's annual Arctic report card, which was prepared this year by 69 researchers in eight countries. "A return to previous Arctic conditions is unlikely," wrote the scientists in the report. "Record temperatures across Canadian Arctic and Greenland, a...

Researchers at the University of British Columbia are deploying an underwater robot to survey ice-covered ocean in Antarctica from October 17 through November 12. Scientists predict that the sea ice area around Antarctica will be reduced by more than 33 percent by 2100, accelerating the collapse of ice shelves. Up to hundreds of meters thick, ice shelves are floating platforms of ice that cover almost half of Antarctica's coastline. The mission will study the effect of ice shelves on the...

The likelihood of summer Arctic ice cover disappearing within the next few years is unlikely, according to researchers from the University of Colorado at Boulder, though the minimum of ice found in the ocean has dipped to its third lowest levels since 1979. According to a press release, scientists at the university's National Snow and Ice Data Center (NSIDC) found that the Arctic ice extent dropped to 1.84 million square miles at its lowest point, on September 10. That is 630,000 square miles...

The Arctic Ocean is covered by a dynamic layer of sea ice that grows each winter and shrinks each summer, reaching its yearly minimum size each fall. While the 2010 minimum remains to be seen, NASA's Aqua satellite captured this snapshot on Sept. 3. How does the Aqua satellite "see" sea ice? Microwaves. Everything on Earth's surface -- including people -- emits microwave radiation, the properties of which vary with the emitter, thereby allowing the AMSR-E microwave sensor on Aqua to map the...

Melting sea ice in the southern Arctic Ocean has caused tens of thousands of walruses to come ashore in northwest Alaska. US federal scientists say the move to shore by these marine mammals is unusual for the United States- although this has happened at least twice before, in 2007 and 2009. In those years Arctic sea ice was also near record low levels. U.S. Geological Survey biologist Anthony Fischbach told The Associated Press (AP) in a phone interview that the walruses "stretch out for...

GREENBELT, Md., Sept. 1 /PRNewswire-USNewswire/ -- Operation IceBridge - a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice - is soon to embark on its fourth field season in October. The mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.

The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists at the Alfred Wegener Institute are concerned about the long-term equilibrium in the Arctic Ocean. They have indications that the mass of sea ice is dwindling because its thickness is declining. To substantiate this, they are...

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...
