Data Center Description
The Center for Geophysical Studies of Ice and Climate (CEGSIC) is a National Science Foundation sponsored research project based in the Physics Department at St. Olaf College. Their main goal is to understand the response of the world's ice masses to global change. More specifically, we utilize the tools of ice-penetrating radar and satellite imagery to study the dynamics of glaciers and ice sheets in various parts of the world. Ice radar is an remote sensing technique analogous to sonar in water, except it works with electromagnetic waves instead of acoustical waves. Echoes arise from the ice/bedrock interface, from water and air pockets, and also from volcanic debris layers which depict how the ice deforms as it flows. Satellite remote sensing is a complementary technique which gives information about surface topography and motion.
