Abstract:
During an extensive field program, glaciologcal data have been collected at Nioghalvfjerdsfjiorden Glacier (79 North Glacier) in NE-Greenland in 1997 and 1998. A central part of the field work was dedicated to seismic investigations of the floating part of the glacier, determining the ice thickness, the underlying water column depth and the bedrock elevation. The seismic reflexion measurements were carried out with a 24-channel seismograph (Strataview). 600g explosives were used as energy source at a distance of 100 m from the first geophone. Details about the measurements and the project can be found in Mayer et al. (2000).
