Performance of light vibroseis sources on polar firn
Small vibrator sources have been succesfully operated on cold Alpine firn in the last years. Here we present results from first operations on the Antarctic plateau, near Kohnen station, Dronning Maud Land with the electrodynamic vibrator system ELVIS. Because of its light weight, such vibrator sourc...
