This British Geological Survey (BGS) marine geophysical survey took place in June to August 1984 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 sidescan sonar. Sub-bottom seismic profiling data were collected using Airgun, Pinger and Sparker. Gravity and Magnetometer data were recorded. These records are archived by BGS. Technical details of the survey data are contained in BGS report WB/89/6R.
