A new NASA study shows that the rising frequency and intensity of arctic storms over the last half century, attributed to progressively warmer waters, directly provoked acceleration of the rate of arctic sea ice drift, long considered by scientists as a bellwether of climate change. NASA researcher Sirpa Hakkinen of Goddard Space Flight Center in Greenbelt, Md., and colleagues from Woods Hole Oceanographic Institution, Woods Hole, Mass., and the Arctic and Antarctic Research Institute, St....

After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest Passage. This year marked the first time since satellite measurements began in the 1970s that the Northern Sea Route, also known as the Northeast Passage, and the Northwest Passage were both open at the same time for a few weeks. "NIC analysis of ESA's Envisat and other...

Researchers from TU Delft joined forces with the Center for Space Research (CSR) in Austin, Texas, USA, to develop a method for creating an accurate picture of Greenland's shrinking ice cap. On the strength of this method, it is now estimated that Greenland is accountable for a half millimeter-rise in the global sea level per year. These findings will be published in the scientific journal Geophysical Research Letters in early October. The research was based on data from the German-American...

Following a record-breaking season of arctic sea ice decline in 2007, NASA scientists have kept a close watch on the 2008 melt season. Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before. Each year at the end of summer, sea ice in the Arctic melts to reach its annual minimum. Ice that remains, or "perennial ice," has survived from year to year and contains...

U.S. scientists say global warming caused arctic sea ice to melt to its second-lowest level this year, rising slightly from 2007's record but still showing a downward trend. The National Snow and Ice Data Center said in March, that the thick, older sea ice was continuing to decline. According to NASA-processed satellite microwave data, this perennial ice used to cover 50-60 percent of the Arctic. Researchers found this winter it covered less than 30 percent. Temperatures have been lower in...

Observations on ice coverage and thickness show that sea ice in the Arctic may be headed for a consecutive record low in a trend that demands action from governments pursuing a new climate pact, the Worldwide Fund for Nation said on Monday. "If you take reduced ice thickness into account, there is probably less ice overall in the Arctic this year than in any other year since monitoring began," said Martin Sommerkorn, senior climate adviser of the WWF's Arctic program. "This is also the first...

Experts reported on Friday that the amount of sea ice around Antarctica has grown in recent Septembers in what could be an unusual side-effect of global warming. Since the late 1970s, in the southern hemisphere winter, when emperor penguins huddle together against the biting cold, ice on the sea around Antarctica has been increasing, perhaps because climate change means shifts in winds, sea currents or snowfall. But Arctic sea ice at the other end of the planet is now close to matching a...

By Richard Sadler New research by the Met Office has revealed that official predictions for sea level rise are out of date because they do not include the effects of melt water from the massive Greenland ice sheet.The situation is so serious that the Environment Agency is being forced to review its flood defence plans for London. Contingency plans for other major low-lying cities Hull, Newcastle, Glasgow and Norwich will also have to be re-evaluated.The extent of the problem was revealed...

Scientists said on Tuesday the ice shelves in Canada's High Arctic have lost a colossal area measuring 19 square miles after it broke away last month. The remaining shelves attached to Ellesmere Island, which have lasted for thousands of years, have seen almost a quarter of their cover break away. The Markham Ice Shelf, one of just five remaining ice shelves in the Canadian Arctic, split away from Ellesmere Island in early August.  Scientists also reported that two large chunks totaling...

Scientists at the National Snow and Ice Data Center say Arctic Ocean sea ice has melted to the second lowest level since satellite observations began.On Monday, they recorded Sea ice melt that exceeded the low recorded in 2005, which had held second place.Ice in summer 2008 has a chance to diminish below the record low set last year, according to scientists at the National Snow and Ice Data Center.Some environmentalists groups are calling the rapid melts another alarm bell warning...

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...
