Detailed Description
Scientist uses radio-echo-sounding to study firn compaction on Wolverine Glacier, Alaska. Radio-echo sounding (RES) is a technique used by glaciologists to measure the internal structure, ice thickness and sub-ice morphology of glaciers. This tool is equivalent to X-rays for the medical profession and the physicists.
