Latest Polar ice packs Stories
NASAâ€™s first oceanographic research expedition got underway this morning as the US Coast Guard icebreaker Healy steamed out of this island fishing port in the North Pacific.
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.
NASAâ€™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 oceanâ€™s chemistry and ecosystems that play a critical role in global climate change.
Less ice covers the Arctic today than at any time in recent geologic history.
Melting sea ice has been shown to be a major cause of warming in the Arctic.
Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise.
Close to 50 years of data show the Devon Island ice cap, one of the largest ice masses in the Canadian High Arctic, is thinning and shrinking.
The US National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records.
In 2007, the Arctic lost a massive amount of thick, multiyear sea ice, contributing to that year's record-low extent of Arctic sea ice.
The original proposal to build a satellite that would measure ice-thickness change came from Prof. Duncan Wingham in 1998.
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...
