A seismic refraction survey on sea ice near Butter Point, New Harbour, McMurdo Sound
Listed in NASA Earthdata CMR
Description
A seismic refraction survey was conducted on sea ice near Butter Point to provide data on sediment thickness for possible further drilling and to investigate the cause of a reported gravity anomaly. 12 vertical geophones were spaced at 29.95m intervals, frozen in to holes chipped in the sea ice and covered by 100-200mm of snow. Two reverse lines were shot, using four shot points.
