abstract: This British Geological Survey (BGS) marine geophysical survey took place in April and May 1985 to the west of the Hebrides on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The objective was to survey the St. Kilda sheet and part of the Little Minch sheet. Sea floor data were collected using echosounder and Transit Sonar. Sub-bottom seismic profiling data were collected using Airgun/Water gun, Pinger and Sparker. Gravity and Magnetometer data were recorded. These records are archived by BGS. Techical details of the survey are contained in BGS report WB/89/6R.
additional info: Information for this survey is sourced from BGS report WB/89/6R. Vessel type - motor vessel. Navigation - Transit satellite, Magnavox integrated system; in deep-water Magnavox MX1107L system used. Positions transformed to Internation Spheroid, European Datum 1950. Accuracy details - (Position +/- 200m in water depth &lt400m). Echo-sounder - Atlas Deso 20. Transit sonar. Geophysical equipment: Airgun/Water gun, Pinger and Sparker. Magnetometer - Barringer M123; Gravity meter LaCoste and Romberg S75. For more detailed information see the Cruise Report.
