International scientists, researchers and decision makers met at the "ËœSpace and the Arctic workshop' to identify the needs and challenges of working and living in the rapidly changing Arctic and to explore how space-based services can help to meet those needs. The workshop, held from 20 to 21 October in Stockholm, Sweden, was organized by the Swedish National Space Board and the Swedish Meteorological and Hydrological Institute together with ESA, EUMETSAT and the EC. The warmer...

WASHINGTON, Oct. 8 /PRNewswire-USNewswire/ -- NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Researchers will work from NASA's DC-8, an airborne laboratory equipped with laser mapping instruments, ice-penetrating radar...

Low-level aerial surveys aim to understand rapid Antarctic melting Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago. The flights, dubbed Operation Ice Bridge, are an effort by NASA in cooperation with university researchers to image what is happening on, and under, the ice, in order to...

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...

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...

NASA and the National Snow and Ice Data Center in Boulder, Colo., will hold a media teleconference on Monday, April 6, at 11 a.m. EDT, to present the latest observations of sea ice conditions in the Arctic. Sea ice cover over the Arctic Ocean typically reaches its maximum geographic extent and thickness just as spring begins in the Northern Hemisphere. In 30 years of satellite measurements of sea ice, the six smallest wintertime measurements all have occurred since 2004. Scientists also have...

NASA says it has produced a unique movie about Earth's changing ice and snow cover to be shown at U.S. science centers and museums. The National Aeronautics and Space Administration says the Goddard Space Flight Center in Greenbelt, Md., produced the film for its Science on a Sphere projection system -- a fully spherical video technology. The six-foot spheres are installed in more than 30 locations around the world. The space agency said Frozen uses satellite data to investigate all parts of...

NASA has created a unique "spherical" movie about Earth's changing ice and snow cover as captured by NASA spacecraft. "Frozen," a 12-minute, narrated film, premieres at science centers and museums March 27. NASA's Goddard Space Flight Center in Greenbelt, Md., produced the film for the "Science on a Sphere" projection system, a fully spherical video technology developed by the National Oceanic and Atmospheric Administration. The six-foot spheres are installed in more than 30 locations around...
