  • Report: Davies, AJ, Mould, AS, Roberts, PR. & Kimber, PD. 1974. Geophysical Surveys in the Celtic Sea Area, MV Briarthorn. MGU Project 74/06. (IGS Report No 52, WB/MG/74/52) Navigation: Decca Main Chain. Equipment: EG&G 9 element spark array with Bolt and Geomechanique hydrophone systems and Huntec recorder. Transit Sonar MS 47.

  • This marine geophysical survey was carried out by British Geological Survey (BGS) and engineers from Hunting Surveys Ltd, Sodera and IOS Barry. The survey took place 27 July to 8 August and 5-18 October 1974 in the Northern North Sea on board the MV Briarthorn. The purpose was to collect data to identify trace reflectors and features observed on deep seismic sections from the project area. Sea floor data were collected using Transit Sonar. Subsurface data were gathered using a suite of seismic instruments (airgun, sparker, pinger and watergun), plus a gravity meter and a magnetometer. These data were recorded as paper records and are archived by BGS. Technical details of the survey are contained in BGS report WB/MG/74/53.

  • This geophysical survey has been carried out by British Geological Survey (BGS) for BGS, the survey took place in June 1974 in Plymouth Bay area, western English Channel on board the MV Briarthorn. The purpose was to collect data as part of UK regional mapping programme. The main objectives were the completion of gravity coverage between MOD surveys to the south and the coast of Plymouth Bay. Acquisition of sparker data along deep seismic lines. Completion of routine sparker coverage over the IGS 1:250000 Lands End sheet, and the eastern part of the IGS 1:250000 Lizard sheet. Sub-bottom profiling data were collected using Sparker. Seabed data were collected using Transit sonar. Gravity and Magnetometer data were recorded. Navigation: Decca Main Chain. These data are archived by BGS. Technical details of the survey are contained in BGS report WB/MG/81/114.

  • This marine geophysical survey was carried out by British Geological Survey (BGS) and engineers from Hunting Surveys Ltd, and IOS Barry. The survey took place in August to October 1974 around Shetland, Orkney and off north west Scotland on board the MV Briarthorn. The purpose was to collect data for UK regional mapping. Sea floor data were collected using Transit Sonar. Subsurface data were gathered using a suite of seismic instruments (airgun, pinger and sparker), plus a gravity meter and a magnetometer. These data were recorded as paper records and are archived by BGS. Technical details of the survey are contained in BGS report WB/MG/74/54.

  • Report: Dobinson, A. 1975. Survey Data Report South Forties Area July 1974. Continental Shelf Unit II Survey 74/BR/02. MV Briarthorn.(IGS Report No 62, 98, WB/MI/74/12 & 75/3 & UC97). This survey was carried out in conjunction with sampling survey 1974/2.

  • This sampling and geophysical survey has been carried out by, Institute of Geological Sciences (IGS) now British Geological Survey (BGS) for BGS, the survey took place from August to December 1974 in the Bristol Channel, Irish Sea and English Channel on board the MV Whitethorn. The purpose was to collect data as part of a geological mapping programme. Sample data were collected using Drilling equipment,: Rock Gravity Corer, Sediment Gravity Corer, Vibrocorer and Shipek Grab. These data are archived by BGS. Details of the survey are contained in IGS Annual Report 1974 and IGS report 79/8.

  • This sampling and geophysical survey has been carried out by Institute of Geological Sciences now British Geological Survey (BGS) for BGS, the survey took place in May 1975 in the Thames Estuary from a helicopter. The purpose was to collect data for a helicopter gravity survey for the Applied Geophysics unit. Beach sample data were collected for the marine geology unit for the UK regional mapping programme. Beach photographs taken at some stations. These data are archived by BGS. No BGS survey report currently available.

  • This geophysical and sampling survey has been carried out by Institute of Geological Sciences (IGS) now British Geological Survey (BGS) for BGS, the survey took place in April 1975 in the Clyde and Sea of the Hebrides on board the RRS Challenger. The purpose was to carry out further trials of the IGS submersible Consub in obtaining small cores from solid rock outcrops. Sea floor data were collected using Echo Sounder and Sidescan Sonar. These data are archived by BGS. Details of the survey are contained in IGS Annual Report 1975.

  • 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.
