Full description

The active seismics are all part of a survey of the Sorsdal Glacier. They are designed to measure ice thickness, and the thickness of the water column underneath the ice shelf where the ice is floating. This was part of an investigation to determine the location of the grounding line on Sorsdal Glacier.
