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...

A massive iceberg has broken off from a glacier in Greenland and has started drifting south into shipping lanes and waters occupied by oil rigs, according to a recent Associated Press (AP) report. On Tuesday, AP writer Karl Ritter noted that the iceberg, which detached from the Petermann glacier in Greenland last week, was "an island of ice more than four times the size of Manhattan." He also noted that the 260 square kilometer mass could cause "untold damage" as it drifts south towards 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...

NASA's first oceanographic research expedition got underway this morning as the U.S. Coast Guard icebreaker Healy steamed out of this island fishing port in the North Pacific. The five-week ICESCAPE mission, which stands for "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," is now heading for the Bering Strait on its way north into the Chukchi and Beaufort seas. The science teams on the mission spent a full day on Monday loading scientific gear and supplies...

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...

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...

Less ice covers the Arctic today than at any time in recent geologic history. That's the conclusion of an international group of researchers, who have compiled the first comprehensive history of Arctic ice. For decades, scientists have strived to collect sediment cores from the difficult-to-access Arctic Ocean floor, to discover what the Arctic was like in the past. Their most recent goal: to bring a long-term perspective to the ice loss we see today. Now, in an upcoming issue of Quarternary...

Melting sea ice has been shown to be a major cause of warming in the Arctic, according to a University of Melbourne, Australia study. Findings published in Nature today reveal the rapid melting of sea ice has dramatically increased the levels of warming in the region in the last two decades. Lead author Dr James Screen of the School of Earth Sciences at the University of Melbourne says the increased Arctic warming was due to a positive feedback between sea ice melting and atmospheric...

Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise. The research, published this week in Geophysical Research Letters, is the first assessment of how quickly floating ice is being lost today. According to Archimedes' principle, any floating object displaces its own weight of fluid. For example, an ice cube in a glass of water does not cause the glass to overflow as it melts. But because sea water is warmer and more salty...

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...
