A seismic refraction survey on sea ice at New Harbour and Dailey Islands
Entry ID:
K042_1982_1983_NZ_2
Summary
Abstract:
A seismic refraction survey was conducted on sea ice at New Harbour and the Dailey Islands to provide data on sediment thickness for possible further drilling for Cenozoic investigations in the Western Ross Sea. At New Harbour, two seismic lines, each 8.66km long with shot points at each end and at the centre were laid out in the form of a cross. Water depth was measured at each shot site. At the Dailey Islands, sea bottom depth and dip along the seismic line were determined at each spread by stacking sledge hammer blows on the ice. Two 8.66km lines similar to those at New Harbour were laid out in the for of a "T". Four extra shot points were incldued on line A because a complex sea bottom was expected near the islands.
