Abstract:
Experiments using GPR around Scott Base showed the GPR could detect crevasses on the McMurdo Ice Shelf, in an area near Scott Base where distinctive surface undulations or 'pressure rollers' (pressure ridges) run parallel to the coastline where the ice shelf collides with the coast. In an 8 week period from mid-November 2001 to mid-January 2002, GPR, electromagnetic and spectral analysis of surface wave (SASW) surveys were performed on parts of the Pram Point shelf ice pressure ridges and the surrounding area to determine the internal structure of the rollers and whether zones of weakness could be detected in the ice and their relationship to crevasse formation.
Quality
All of the surveys and data are backed up on CD or DVD. The files are raw data files and often quite large (e.g. many Mbytes for ONE radar file). Please contact the investigator for access.
