This British Geological Survey (BGS) marine geophysical survey took place in May to July 1985 in the Minches on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The objectives were a gravity survey of the Minches and a number of high resolution seismic profiles. Sea floor data were collected using echosounder and Transit Sonar. Sub-bottom seismic profiling data were collected using Pinger and Sparker. Gravity data were also recorded. These records are archived by BGS. Technical details of the survey data processing are contained in BGS report WB/89/9R.
Information for this survey is sourced from BGS report WB/89/9R. Vessel type - motor vessel. Navigation - Transit satellite, Magnavox integrated system. 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: Pinger and Sparker. Gravity meter LaCoste and Romberg S75. For more detailed information see the Cruise Report.
