LONDON -- A British explorer said Tuesday he is planning the most accurate survey of the thickness of the Arctic ice during a 1,240-mile trek to the North Pole to gauge the effects of global warming. The Vanco Arctic Survey will take millions of readings of the thickness and density of the ice and snow next year to try to provide the clearest picture of the polar ice cap and how long it will last. Explorer Pen Hadow's three-member team will pull a sled-mounted, ground-penetrating radar from...

PASADENA, Calif. - A new NASA-led study found a 23-percent loss in the extent of the Arctic's thick, year-round sea ice cover during the past two winters. This drastic reduction of perennial winter sea ice is the primary cause of this summer's fastest-ever sea ice retreat on record and subsequent smallest-ever extent of total Arctic coverage. A team led by Son Nghiem of NASA's Jet Propulsion Laboratory, Pasadena, Calif., studied trends in Arctic perennial ice cover by combining data from...

Melting Arctic sea ice has shrunk to a 29-year low, significantly below the minimum set in 2005, according to preliminary figures from the National Snow and Ice Data Center, part of the University of Colorado at Boulder. NASA scientists, who have been observing the declining Arctic sea ice cover since the earliest measurements in 1979, are working to understand this sudden speed-up of sea ice decline and what it means for the future of Earth's northern polar region. "The decline in the amount...

The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage "“ a long-sought short cut between Europe and Asia that has been historically impassable. In the mosaic image above, created from nearly 200 images acquired in early September 2007 by the Advanced Synthetic Aperture Radar (ASAR) instrument aboard ESA's Envisat satellite, the dark gray colour represents the ice-free...

WASHINGTON -- More than two-thirds of the world's polar bears will be killed off by 2050 - including the entire population in Alaska - because of thinning sea ice from global warming in the Arctic, government scientists forecast Friday. The agency projects that polar bears during that time will lose 42 percent of the Arctic range they need to live in during summer in the Polar Basin when they hunt and breed. Polar bears depend on sea ice as a platform for hunting seals, which is their primary...

WASHINGTON -- There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported. "Today is a historic day," said Mark Serreze, a senior research scientist at the center. "This is the least sea ice we've ever seen in the satellite record and we have another month left to go in the melt season this year." Satellite measurements showed 2.02 million square miles of ice in the Arctic, falling below the Sept. 21,...

OSLO, Norway -- Danish scientists head for the Arctic ice pack on Sunday seeking evidence to position Denmark in a race to claim the potentially vast oil and other resources of the North Pole region. Russia sent two small submarines to plant a tiny national flag under the North Pole last week. Canada, the United States and Norway also have competing claims in the vast Arctic region, where a U.S. study suggests as much as 25 percent of the world's undiscovered oil and gas could be hidden....

A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. During the Arctic Ice Mapping Project, researchers measured critical areas of the island's ice sheet as well as its glaciers and monitored changes that may be connected to global climate change. The science team, using laser and radar instruments aboard aircraft, has been closely monitoring...

BOULDER, Colo. -- Arctic sea ice is melting three times faster than many scientists project, U.S. researchers reported Monday, just days ahead of the next major international report on climate change. Scientists at the National Center for Atmospheric Research and the University of Colorado in Boulder concluded, using actual measurements, that Arctic sea ice has declined at an average rate of about 7.8 percent per decade between 1953 and 2006. By contrast, 18 computer models used by the...

A new NASA study has found that in 2005 the Arctic replaced very little of the thick sea ice it normally loses and replenishes each year. Replenishment of this thick, perennial sea ice each year is essential to the maintenance and stability of the Arctic summer ice cover. The findings complement a NASA study released in fall 2006 that found a 14-percent drop in this perennial ice between 2004 and 2005. The lack of replenishment suggests that the decline may continue in the near future....

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...
