Rockall Consortium (RCK) Geophysical Survey 1993/2_RCK: Northern Rockall Trough and adjacent areas (04/07/1993 to 14/08/1993)
This geophysical survey has been carried out by Digicon Geophysical, for British Geological Survey (BGS), the Multichannel Deep Seismic survey took place from July to August 1993 in the Rockall area on board the MV Acadian Searcher. The purpose was to collect data as part of Rockall Continental Margin Project: 1) to shoot a grid of lines on eastern flank of Rockall Bank; 2) to shot three long transect lines across Rockall Bank and the Rockall-Hatton Basin down to 18sec two-way time; 3) to acquire gravity data. Sub-bottom profiling data were collected using Airguns. Gravity data were collected. These data were recorded digitally and are archived by BGS. Technical details of the survey are contained in BGS report WB/93/28C and contractor report. GeoIndex Offshore - https://mapapps2.bgs.ac.uk/geoindex_offshore/home.html?cruise=1993/2_RCK&.
