早在20世纪20年代，主动地震测量就是南极冰盖地球物理穿越的重要组成部分。由于地震数据采集需要大量的后勤工作，这些方法在冰厚测量中失去了主导作用，取而代之的是更快的陆基和机载雷达测量。然而，在主动地震勘探（简称可控震源）方面取得的新成就可以开辟新的前景，促进今后在南极洲和格陵兰以及在冰盖和冰川上进行地质和冰川学调查。
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.
