WASHINGTON, Oct. 16, 2014 /PRNewswire-USNewswire/ -- NASA is carrying out its sixth consecutive year of Operation IceBridge research flights over Antarctica to study changes in the continent's ice sheet, glaciers and sea ice. This year's airborne campaign, which began its first flight Thursday morning, will revisit a section of the Antarctic ice sheet that recently was found to be in irreversible decline. http://photos.prnewswire.com/prnvar/20081007/38461LOGO For the next several...

Arctic Melt Ponds
2014-08-05 03:00:50

Kate Ramsayer, NASA's Earth Science News Team Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools. On July 16 and July 17, NASA’s ER-2 aircraft flew above Alaskan glaciers and to the North Pole, carrying an instrument called the Multiple Altimeter Beam Experimental Lidar, or MABEL. MABEL is a laser altimeter,...

Space Laser To Collect Earth Elevation Data During ICESat-2 Mission

redOrbit Staff & Wire Reports - Your Universe Online The laser instrument component of NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) is currently being integrated and tested at the Goddard Space Flight Center in Maryland, US space agency officials announced on Tuesday. The instrument, which is known as the Advanced Topographic Laser Altimeter System (ATLAS), will be used to measure the elevation of the planet’s surfaces, including forests, oceans and even ice...

NASA IceBridge Wraps Up Arctic Field Campaign
2014-05-29 03:43:26

By George Hale, NASA Starting With Sea Ice IceBridge's campaign began on Mar. 10 when NASA's P-3 research aircraft left Wallops for Thule. For the first part of the campaign, researchers studied Arctic sea ice from Thule and Fairbanks, Alaska. Early in each campaign IceBridge spends a week in Alaska to survey sea ice north of Alaska. In addition, researchers study sea ice conditions across the entire Arctic Basin traveling from Thule to Fairbanks and back. IceBridge's sea ice...

April Flowers for redOrbit.com - Your Universe Online Flying over Greenland and the Arctic Ocean in April 2012, a high-altitude aircraft completed the first polar test of a new laser-based technology designed to measure the height of Earth from space. That instrument was the Multiple Altimeter Beam Experiment Lidar (MABEL), an airborne test bed instrument designed for NASA's ICESat-2 mission, which is slated for launch in 2017. MABEL has returned new results demonstrating that a...

NASA Airborne Campaign To Measure Summer Melt Of Greenland Ice Sheet

[ Watch The Video: 5 Questions About LVIS & IceBridge ] NASA For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. NASA's C-130 research aircraft flew from the Wallops Flight Facility in Wallops Island, Va., to Greenland on Wednesday where they will conduct survey flights to collect data that will improve our understanding of seasonal melt and...
