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...

On Aug. 5, 2010, an enormous chunk of ice, about 251 square kilometers (97 square miles) in size, or roughly four times the size of Manhattan, broke off the Petermann Glacier along the northwestern coast of Greenland. The Petermann Glacier lost about one-quarter of its 70-kilometer-long (40-miles) floating ice shelf, according to researchers at the University of Delaware, Newark, Dela. The recently calved iceberg is the largest to form in the Arctic in 50 years. Icebergs calving off the...

During NASA's ICESCAPE voyage to the Arctic, scientists have been looking at the phytoplankton in the Arctic's Chukchi Sea -- how many, how big and at what depths they are found. But there are other ways of looking at these small life forms. "We measure phytoplankton in terms of their pigments and light absorption properties," said Stan Hooker of NASA's Ocean Biology and Biogeochemistry Calibration and Validation Office at Goddard Space Flight Center, Greenbelt, Md. Hooker, Joaquin Chaves and...

Researchers from German Alfred Wegener Institute and KlimaCampus present forecasts on September minimum A critical minimum for Arctic sea ice can also be expected for late summer 2010. Scientists from the German "Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI)" in Bremerhaven and from "KlimaCampus" of the University of Hamburg have now published their projections in the current Sea Ice Outlook. The online publication compares the forecasts on ice...

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...
