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...

As Arctic sea-ice recedes inexorably towards another record summer minimum, scientists have highlighted the exceptional contribution that satellites have made to the International Polar Year and charting the effects of climate change. Celebrating the remarkable accomplishments of the International Polar Year (IPY), the IPY Oslo Science Conference last week drew together 2400 researchers, educators and members of northern communities "“ making it the biggest polar science meeting ever...

North America, Europe and eastern Asia could see more cold, moist and snowy winters much like the one that just passed, according to one top scientist. James Overland of the US National Oceanic and Atmospheric Administration (NOAA) told the AFP news agency, "Cold and snowy winters will be the rule rather than the exception." It may seem counter-intuitive, but warmer Arctic climates caused by climate change influence air pressure at the North Pole, which shifts wind patterns in such a...

NASA's first dedicated oceanographic field campaign goes to sea next week to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change. The ICESCAPE mission, which stands for "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas along Alaska's...

Arctic Ocean

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...
