This British Geological Survey (BGS) geophysical and sampling survey took place in May 1974 in the South Forties area using the MV Whitethorn. The main purpose was to compare methods of geophysical profiling and geotechnical testing. Sea-bed samples and cores at fifty seven stations were collected using Gravity corer, Vibrocorer and shipek grab/camera. Geophysical lines run included Pinger, sparker, boomer and echosounder equipment. Position fixing during the cruise was Decca Main Chain. These data are archived by BGS. Technical details of the survey are contained in BGS Technical Reports WB/MI/74/10.

This geophysical and sampling survey has been carried out by Institute of Geological Sciences now British Geological Survey (BGS) for BGS, the survey took place in September 1975 mainly in the area of Haig Fras on board the MV Gardline Locator. Shallow geophysical surey work took place at night with sampling operations during the day.The purpose was to collect data as part of the UK regional mapping programme. Sub-bottom profiling data were collected using pinger and sparker. Sea-bed samples were collected using a gravity corer and shipek grab. These data are archived by BGS. No BGS survey report currently available, IGS 1975 annual report contains summary..

This British Geological Survey (BGS) marine sampling and geophysical survey took place from the May to June 1975 in the North Sea on board the RRS John Murray. Sub-bottom seismic profiling data were collected using Pinger and Sparker. Sample data were collected using dredge, gravity corer and shipek grab. These records are archived by BGS. No cruise report available.

This British Geological Survey (BGS) regional geophysical and sampling survey took place in May 1976 in North Sea, west of Scotland on board the RRS Challenger. The purpose was to gather data which could be used to map the regional geology of the area. Seabed samples and cores were collected using IGS Shipek grab, Gravity corer and midi drill and unmanned submersible Consub. Sea floor data were collected using a echo-sounder and a precision depth recorder. Subsurface seismic data were gathered using a pinger. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report 76/7.

Multichannel airgun survey carried out in the SW Approaches during October 1976; March, April, December 1977. Coverage 2564Km.

This British Geological Survey (BGS) regional marine sampling survey took placein May 1976 in the North Sea on board the RRS John Murray. The purpose was to gather data which could be used to map the regional geology of the area and undertake geochemical analysis.Seabed samples and cores were collected using Shipek grab and cone dredge. A total of 1750 km of data were collected in a grid of survey tracks. Sea floor data were collected using a transit sonar. Subsurface data were gathered using a pinger. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report 76/10.

During the period 31 January 1977 to 15th February 1977 approximately 490km of subsurface data in UK blocks 97 and 98 (Bournemouth Bay) were acquired for The Institute of Geological Sciences (BGS) by S & A Geophysical Ltd and subsequently processed by them at their Swanley, England processing centre. survey vessel: M/V Oil Hunter.
