Robotic Probe Developed to Study Antarctic Lake May Explore Ice-bound Worlds

5/31/2007 A robotic probe designed to draw a three-dimensional underwater map of an ice-bound Antarctic lake may prove an ideal tool to search for life on frozen planets or moons. A three-year, $2.3 million NASA project is building the probe--dubbed ENDURANCE (Environmentally Non-Disturbing Under-ice Robotic ANtarctiC Explorer)--that will map Antarctica's Lake Bonney, located in the McMurdo Dry Valleys.

Training Robots as Polar Explorers

5/31/2007 Engineers at the U.S. Army's Cold Regions Research and Engineering Laboratory (CRREL) are studying how to use robots to assist in making scientific measurements in the Polar Regions. They have recorded a Greenland field test on video. More

NASA Mission Checks Health of Greenland's Ice Sheet and Glaciers

5/30/2007 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. During the 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. More

NASA Researcher Finds Days of Snow Melting on the Rise in Greenland

5/29/2007 In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations. More

A System of Lakes and Rivers Buried Under the Antarctic Ice Sheets is "One of the Last Unexplored Places on Earth"

5/24/2007 A vast system of lakes and other aquatic features under the Antarctic ice sheet is one of the "last unexplored places on Earth" and great care will have to be taken in the years ahead as scientists consider how to sample the waters. More

USGS Alaska Science Center Developing Circumpolar Map

5/23/2007 The USGS Alaska Science Center is developing a geologic map and spatial database of the Circumpolar Region. The map will represent the region north of 60 degrees latitude and will cover about 90 percent of Alaska's land area. It is expected to be completed in 2008. More

NASA Finds Vast Regions of West Antarctica Melted in Recent Past

5/15/2007 A team of NASA and university scientists has found clear evidence that extensive areas of snow melted in west Antarctica in January 2005 in response to warm temperatures. This was the first widespread Antarctic melting ever detected with NASA's QuikScat satellite and the most significant melt observed using satellites. More

Space Station Provides New 'Window' for International Polar Year

5/11/2007 Crew members on NASA's International Space Station are supporting the IPY scientific program by taking new snapshots of Earth's polar regions from the unique vantage point of space. More

Visit the Arctic National Wildlife Refuge...via the Net

5/8/2007 Established in 1960 and managed by the U.S. Fish & Wildife Service, the Arctic National Wildlife Refuge encompasses the traditional homelands and subsistence areas of Inupiaq Eskimos and Athabascan Indians. The 19.2-million acre refuge is home to an unbroken continuum of arctic and subarctic ecosystems. More

Labrador Retrievers Assist Ringed Seal Researchers

5/4/2007 Working dogs have long been integral to Arctic cultures, but today research biologists are relying on canine co-workers to sniff out ringed seals, whose annual movements and breeding habitats they are studying. More
