Without its insulating ice cap, Arctic surface waters warm to as much as 5 C above average
12-12-2007 · EurekAlert!Record-breaking amounts of ice-free water have deprived the Arctic of more of its natural "sunscreen" than ever in recent summers. The effect is so pronounced that sea surface temperatures rose to 5 C above average in one place this year, a high never before observed, says the University of Washington oceanographer who has compiled the first-ever look at average sea surface temperatures for the region.

- Researchers setting up observatories to examine changes under the Arctic ice
04-16-2007 · EurekAlert!
Researchers from the Woods Hole Oceanographic Institution are venturing this month to the North Pole to deploy instruments that will make year-round observations of the water beneath the Arctic ice cap. Scientists will investigate how the waters in the upper layers of the Arctic Ocean -- which insulate surface ice from warmer, deeper waters -- are changing from season to season and year to year as global climate fluctuates.

- MCA backs closure of Arctic waters
06-12-2007 · EurekAlert!
The Marine Conservation Alliance supports action today by the North Pacific Fishery Management Council to close all federal waters north of the Bering Strait to commercial fishing until a management plan, including habitat protection, is fully developed."Climate change is having a significant effect on the Arctic, opening previously ice-covered waters and drawing cold water species further north," said MCA's Dave Benton. "The council is right to look at closing these waters as a precautionary measure."

- Melting of the Greenland ice cap may have consequences for climatic change
05-07-2007 · EurekAlert!
At the last ice age, before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which covered the British Isles had already begun to affect the circulation of the ocean currents. Based on this observation, scientists consider that the acceleration of the melting of the Greenland ice cap could play an important role in the development of climate change.

- Global warming is evaporating Arctic ponds, new study shows
07-02-2007 · EurekAlert!
High Arctic ponds -- the most common source of surface water in many polar regions -- are now beginning to evaporate due to recent climate warming, say two of Canada's leading environmental scientists.

- Warm winter also in the Arctic
03-29-2007 · EurekAlert!
Central Europe is not the only place where the past, warm winter has caused record temperatures. Unusually mild temperatures also prevented ice formation in the Arctic, specifically in the region around Spitsbergen. This is the conclusion drawn by scientists of the Alfred Wegener Institute for Polar and Marine Research and the German Aerospace Centre (DLR). Both institutes are members of the Helmholtz Association of German research centres in collaboration with the European Space Agency.
