Summary
[edit]DescriptionDriving the Radar Sled (5433412735).jpg |
Lora Koenig, of NASA's Goddard Space Flight Center, drove the snowmobile on Dec. 13, 2010, that pulled the radar sled holding two radars across a total of 400 kilometers of Antarctic snow. The radars, developed at University of Kansas' Center for Remote Sensing of Ice Sheets, detect layers in the snow related to accumulation over a larger area than possible from ice cores and snow pits. The traverse was the first of two field campaigns to study snow accumulation on the West Antarctic Ice Sheet and tie the information back to larger-scale data collected from satellites.
