This geophysical magnetic survey has been carried out by, Institute of Geological Sciences (IGS) now British Geological Survey (BGS) in cooperation with Hydrogrphic Department of the Navy for BGS, the survey took place from spring/summer 1972 in the western English Channel on board the MV Researcher. The purpose was to collect data as part of a regional geophysical survey programme. Details of the survey are contained in IGS Annual Report 1972.

This marine multibeam geophysical survey took place in August/September 2010 between Little Cumbrae Island and Hunterston on board the RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) on behalf of Magnox North Ltd. Phase 1 (1-8 August 2010) collected Multibeam data and Phase 2 (7-8 September 2010) collected Surface Tow Boomer and Magnetometer data. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. Sub bottom seismic data were collected using an Applied Acoustics Surface Tow Boomer (STB). Magnetometer data were collected using a SeaSpy Magnetics Magnetometer. These data are archived by BGS. Paper records were also generated for Boomer. Technical details of the survey are contained in Cruise report BGS CR/11/38. Geophysical dataset interpretation is contained in report BGS CR/10/142.

The Institute of Geological Sciences now British Geological Survey (BGS) were invited by French institutes BRGM and CNEXO to participate in a magnetic and shallow seismic survey in the English channel between Cherbourg and Falmouth on the first operational cruise of the new French oceanographic ship Noroit in August 1971.

This geophysical survey has been carried out by British Geological Survey (BGS) for BGS, the survey took place in July 1989 off the coast of East Anglia on board the MV Shorething. The purpose was to collect data as part of the UK mapping programme for 1:50k special sheets. Sea floor data were collected using echosounder. Sub-bottom profiling data were collected using surface tow boomer and sidescan sonar. These data are archived by BGS. No BGS survey report currently available.

Wessex Archaeology (WA) was commissioned by Cadw to acquire, process and interpret marine geophysical data over a number of known and suspected wreck site locations off the coast of Wales. This survey was conducted under the Protection of Wrecks Act (1973) contract and the data is Crown Copyright©. The data were acquired and processed by Wessex Archaeology. The marine geophysical surveys targeted a total of nine suspected wreck locations in Milford Haven area, off the coast of South Wales, seven of which represent the locations for the remains of 19th century Welsh vessels associated with the coal mining industry. Additional survey data were acquired over two 20th century sites within the Milford Haven, the Thor and the Sunderland. The acquisition of these data aimed to assist RCAHMW maritime team and the Sunderland Trust with on-going archaeological research and fund-raising. The marine geophysical surveys also targeted a total of ten suspected and known wreck site locations off the coast of Lleyn peninsula in North Wales. These included eight unconfirmed positions of 19th century Welsh vessels associated with the slate mining industry, two designated sites the Diamond and the Tal-Y-Bont, and the marine hazard of St Patrick’s Causeway with the aim of discovering new wreck sites. The project aimed to acquire marine geophysical data consisting of high resolution sidescan sonar and magnetic gradiometer data over a total of total of 21 known and suspected wreck positions and along the known marine hazard of St. Patrick’s Causeway. Since the sites were located in two different areas, they were surveyed during two separate surveys from the Pembroke based vessel Blue Shark. The first session surveyed sites mostly off Milford Haven in south Wales between 17th and 18th April 2010. The second session surveyed sites off the coast of Lleyn peninsula and along St. Patrick’s Causeway in north Wales between 23rd April 2010 and 2nd May 2010 with a day of mobilisation and a day of demobilisation at the start and end of the survey session. The geology and geophysics component of the data are archived at British Geological Survey (BGS) MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Data were also provided to other archive centres as appropriate.

This British Geological Survey (BGS) marine geophysical and multibeam survey took place in May/June 2006 in the Rockall-Hatton-Faeroes region west of Scotland on board the RRS Charles Darwin. The purpose was to define the size and shape of the basalt window, identify and/or contrain compressional folds/faults/thrusts and to investigate the siesmo-stratigraphy of the Faeroe-Bank Channel to identify potential borehole locations. Additional seismic reflection data were run south of St Kilda and Stanton Bank. Subsurface seismic data were collected using an airgun, sparker and pinger. Seafloor bathymetry data were collected using a Simrad EM12 multibeam system and magnetic and gravity data were also collected. All data were recorded digitally. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report IR/06/076 (http://nora.nerc.ac.uk/id/eprint/7301/) and Report on a survey over Stanton Bank 4 for MESH, June 2006 (http://nora.nerc.ac.uk/id/eprint/7422). A preliminary overview and interpretations of data gathered are contained in Geological Summary Report CR/06/190 (http://nora.nerc.ac.uk/id/eprint/507380/).

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) marine geophysical survey took place in May 1969 in the Firth of Clyde on board the MV Moray Firth IV. The purpose was to investigate the superficial deposits of the clyde area, this survey was Phase 1 of a 5 phase project. Sea floor data were collected using echosounder and sidescan sonar. Sub-bottom seismic profiling data were collected using Pinger and Sparker. These records are archived by BGS. Details of the survey are contained in IGS report 73/9.

This British Geological Survey (BGS) marine geophysical survey took place in April and July 1985 in the North Sea on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The objectives were to investigate igneous bodies in the Forties area and acquire gravity and magnetic data along BIRPS deep seismic lines. Sea floor data were collected using echosounder. Gravity and Magnetometer data were recorded. These records are archived by BGS. Technical details of the survey are contained in BGS report WB/89/8R.
