This British Geological Survey (BGS) marine geophysical survey took place in May to June 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 Miller and Flett map sheets and part of the Foula sheet. Sea floor data were collected using Echosounder and Sidescan Sonar. Sub-bottom seismic profiling data were collected using Airgun, Deep-tow Boomer, Pinger, Sparker and Deep-tow Sparker. Gravity and Magnetometer data were recorded. These records are archived by BGS. No survey report currently available.

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.

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.

Report: Armstrong, EJ. 1979. Cruise Report for Project 79/14, West Shetland and Project 79/15, Bosies Bank. (IGS Report No 101). Project 79/14 was designed to provide regional geophysical coverage of the Foula sheet, of the IGS 1:250000 map series, on a N-S, E-W grid of lines at approximately 15km by 9 km spacing. A number of gravity lines were also to be run over the Orkney sheet to complete gravity coverage in that area. In addition, some regional geophysical lines were to be surveyed on the Halibut Bank sheet after a study of the FLAGS pipeline route with the Huntec deep tow boomer. The watergun provided superior records to those of the airgun giving resolution comparable to the sparker in fair weather, down to 800ms of sediments. Up to 400ms penetration was achieved by the sparker, while the boomer provided good resolution in the shallow section. In depths less than 300m the transit sonar was used.

This British Geological Survey (BGS) marine geophysical survey took place from the May to June in the SW Approaches on board the TSS profiler. The purpose was to collect data for regional survey of the UK continental Shelf. See Survey 1973/7 for the second phase of the project. A total of 6395km over 91 survey lines were collected during 1973/6 (Lines 1-49) and 1973/7 (Lines 50-91) surveys. Sea floor data were collected using echo sounder and transit sonar. Sub-bottom profiling data were collected using gravity meter; magnetometer; pinger and sparker. The data were recorded as paper records. These data are archived by BGS. Technical details of the survey are contained in BGS report WB/MG/74/48.

Report: Brett, CP. 1981. Cruise Report on Project 81/04. A Regional Geophysical Survey in the Northern North Sea. (IGS Report No 120) The primary objectives were to survey the Fladen sheet area of the IGS 1:250000 map series and to run seven north-south lines to complete the coverage of the Forties and Cod shhet areas. A secondary objective was to complete a gravity survey.

This British Geological Survey (BGS) marine geophysical survey took place in May and June 1985 to the west of Scotland on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The main objective was to survey part of the Peach sheet. Sea floor data were collected using echosounder and transit sonar. Sub-bottom seismic profiling data were collected using Airgun/Water gun; Pinger; Sparker and surface tow Boomer. Gravity and Magnetometer data were recorded. These records are archived by BGS. Technical details of the survey are contained in BGS report WB/89/11R.

Report: Brett, CP. 1981. Cruise Report on Project 81/03. A Regional Geophysical Survey in the Southern North Sea. (IGS Report No 119) The primary objective was to complete the geophysical survey of the Tyne-Tees, California and Silver Well sheets of the IGS 1:250000 map series in advance of bottom sampling programme.
