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 marine geophysical and sampling survey took place in September 1975 in Malin Sea on board the MV Whitethorn. 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 Gravity corer, Vibrocorer and borehole drilling. Sea floor data were collected using a echo-sounder. Subsurface data were gathered using a pinger. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report 75/17.

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.

This high resolution marine multi-channel seismic survey commissioned by the Institute of Geological Sciences on behalf of Department of Energy took place in the Northern North Sea during 1st-27th November 1979 (Phase 1) aboard MV Aqua Star and 1st-14th February 1980 (Phase2) aboard Gardline Tracker. Phase 1 (Lines 1-5) was carried out by Fairfield Auatronics Ltd and Phase 2 (lines 5B-9) by Gardline surveys Ltd. Line coverage total 445km (Phase1 - 180km; Phase 2 - 265km). Sea floor data were collected using Echo sounder. Subsurface seismic data were gathered using a 9/15KJ sparker and line 4, Fairflex sleeve exploder. Survey details are contained in Fairfield and gardline acquisition reports and BGS technical report WB/MG/81/124.

This geophysical survey has been carried out by, British Geological Survey (BGS), the survey took place in July 1991 in the North Sea on board the RRS Challenger. The purpose was to collect data to investigate gas-leakage phenomena from pockmarks in the North Sea. Sea floor data were collected using Sidescan Sonar. Sub-bottom profiling data were collected using Deep Tow Boomer. These data were recorded digitally and are archived by BGS.

This geophysical survey has been undertaken by University College of North Wales (UCNW) for Natural Environment Research Council (NERC), the survey took place in September 1992 in the Tees, Seal Sands area on board the Sandpebbler. The purpose was to collect data as part of the NERC Land-Ocean Interaction Study (LOIS). British Geological Survey were a participant in the LOIS study. Sub-bottom profiling data were collected using surface tow boomer. Navigation positioning GPS system. These data are archived by UCNW.
