The U.S. space agency says it is ready to start a study of the Earth's southern ice-covered regions to identify changes in sea ice, ice sheets and glaciers. On Oct. 12, NASA's Operation Ice Bridge resumes when the space agency's DC-8 -- the largest aircraft in its science fleet -- leaves the Dryden Flight Research Center in California for Punta Arenas, Chile, where it will be based through mid-November. For six weeks, the Ice Bridge team will traverse the Southern Ocean for up to 17 flights...

According to a study that might help predict rising sea levels linked to climate change, scientists are surprised at how fast coastal ice in Antarctica and Greenland is thinning. Scientists at the British Antarctic Survey (BAS) and Bristol University said that glaciers speeding up when they flowed into the sea caused the biggest loss of ice, which was seen by analysis of missions of NASA satellite laser images. "We were surprised to see such a strong pattern of thinning glaciers across such...

This summer's melt of Arctic sea ice might not have been quite as bad as the past two years, but satellite images reveal that it has now had the third biggest melt in 30 years, according to U.S. government scientists. The announcement was made on Thursday by the National Snow and Ice Data Center, which reported that the Arctic sea ice pack had reached its yearly minimum just last Saturday. It will not begin to grow again until fall begins. As of last Saturday, the sea ice only covered...

CU-Boulder's Snow and Ice Data Center analysis shows negative summertime ice trend continues The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. While this year's September minimum extent was greater than each of the past two record-setting and near-record-setting low years, it is still...

Arctic thawing is likely to result in worldwide consequences - from an increase in greenhouse gases and global weather pattern changes, according to a WWF report on Wednesday. The World Wildlife Fund released a new study, titled "Arctic Climate Feedbacks: Global Implications," Wednesday that found that Arctic ice is shrinking at a much quicker pace than previously expected. The thawing Arctic is likely to have far-reaching implications that will affect hundreds of millions of people, WWF...

U.S. scientists using satellite data and records from cold war submarine missions have found Arctic Ocean ice thickness has declined 53 percent since 1980. This summer, a group of U.S. and Canadian scientists and students set out from Resolute Bay, Canada, to check the Arctic Ocean ice. One of the scientists was Ron Kwok of NASA's Jet Propulsion Laboratory. Kwok, the space agency said, has long provided checkups on the health of arctic sea ice -- the frozen sea water floating within the...

Back in 2002, NASA created a film using satellite data that took viewers on a tour of Earth's frozen regions. This year, NASA visualizers are taking viewers on a return trip to see how things have changed over the years. "The Tour of the Cryosphere 2009" combines satellite imagery and state-of-the-art computer animation software to create a fact-filled and visually stunning tour that shows viewers the icy reaches of Antarctica, the glacier-pocked regions along the Andes Mountains, the winter...

This summer, a group of scientists and students "” as well as a Canadian senator, a writer, and a filmmaker "” set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. They were headed through the Northwest Passage, but instead of opening shipping lanes in the ice, they had gathered to open up new lines of thinking on Arctic science.Among the participants in the shipboard workshop (hosted by Fisheries and Oceans Canada) was Ron Kwok of NASA's Jet Propulsion...

The conference showed that the Arctic climate is changing rapidly in a number of different ways: The recent rate of decrease in thickness and volume of the Arctic sea ice has been faster than the rate of aerial shrinkage determined from satellites. Given that the present trend of melt continues, some models indicate that it is quite likely that the Arctic Ocean could be ice free in the summer time as early as 2015-16. There has been a rapid increase in the mass-loss from the Greenland ice...

Average ocean surface temperatures reached an all-time high in July, according to a new US agency report. The National Oceanic and Atmospheric Administration's National Climatic Data Center reported Thursday that the average global ocean temperature reached 62.6 degrees in July "“ replacing the previous high temperature record set in 1998. The combined average of global land and surface temperature during July ranked fifth in the overall warmest since records began in 1880, according to...

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...
