Active seismic measurements were an important part of geophysical traverses on the Antarctic ice sheet as far back as the 1920s. These methods lost their leading role for ice thickness measurements to much faster ground-based and airborne radar surveys because of the considerable logistical effort necessary for seismic data acquisition. However, new achievements with a vibrator source in active seismics (vibroseis for short) could open new prospects and foster future geological and glaciological surveys in Antarctica and Greenland and on ice caps and glaciers.
