NASA's first dedicated oceanographic field campaign goes to sea June 15 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 "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment" mission, or ICESCAPE, will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas. A key focus is how changes in...

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...

Rate of ice-cap melt has been accelerating since 1985 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. A paper published in the March edition of Arctic, the journal of the University of Calgary's Arctic Institute of North America, reports that between 1961 and 1985, the ice cap grew in some years and shrank in others, resulting in an overall loss of mass. But that changed 1985 when scientists began...

The U.S. 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. The center said in a statement on Wednesday that cold weather and winds from the north over the Bering Sea and Barents Sea meant the area of ocean covered by ice expanded through last month.  That is two days later than in 1999, the previous latest start to a melting...

The main cause of a rapid global cooling period, known as the Big Freeze or Younger Dryas - which occurred nearly 13,000 years ago - has been identified thanks to the help of an academic at the University of Sheffield. A new paper, to be published in Nature on April 1, 2010, has identified a mega-flood path across North America which channeled melt-water from a giant ice sheet into the oceans and triggering the Younger Dryas cold snap. The research team, which included Dr Mark Bateman from...

As ESA's Mission Scientist for CryoSat, Mark Drinkwater's role in supporting the preparation of the mission has been to ensure that the satellite and data processing systems are compatible with achieving the mission's objectives of deriving accurate measurements of ice-thickness change. Mark Drinkwater, a British national, trained as a geophysicist and performed early pioneering research in the use of altimeter measurements over polar ice. He currently heads the Mission Science Division at...

A mammoth iceberg that struck a glacier off Antarctica, dislodged a newer chunk of ice that could affect ocean currents and also lower the levels of oxygen in the world's oceans, according to Australian and French scientists. The two icebergs are drifting together about 62 to 93 miles off Antarctica after the Feb 12-13 collision, said Neal Young, a glaciologist for the Australian Antarctic Division. The first iceberg, measuring 60 miles long, collided with the Mertz Glacier Tongue and...

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...
