  • This geophysical survey was carried out under contract for the Marine Aggregate Levy Sustainability Fund (MALSF) as part of a Regional Environmental Characterisation, the survey took place from the 8th March to the 18th March 2010. This project is to extend the mapped coverage of the Eastern English Channel Marine Habitat Map (EECMHM) to include the coastal platform from Saltdean east to Dungeness and provide an integrated map dataset covering this extension area The geophysical data was acquired using Surface Tow Boomer and Sidescan sonar equipment. Technical detail of the survey are contained in BGS Open Report OR/10/052.

  • This marine multi-channel geophysical survey commissioned by the British Geological Survey (BGS), acquired by Delta Exploration Inc. and processed by Seiscom Ltd took place October 1972 and July 1973 in the Moray Firth aboard m.v. Caribe Tide. The survey was carried out as part of a regional mapping programme. Data were gathered using the following equipment Navigation: SAT/NAV; Subsurface data were gathered using a gas/airgun (sleeve exploder), 640 km were covered in a grid of 14 lines. These data are archived by BGS. Technical details of the survey are contained in an Acquisition Report (SO/90/029). Seismic Interpretation Training Package, IGS reports 74/12; 75/11 and BGS Techincal Report WB/92/37 includes data from this survey.

  • 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 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.

  • This marine multi-channel geophysical survey commissioned by the British Geological Survey (BGS), acquired and processed by Seismograph Service (England) Ltd took place 22nd August to 24 May and 13th Julyto 29th July 1968 in the Irish Sea aboard m.v. Norbjorn. Navigation: Decca Main chain. Sub surface data were gathered using explosive charges, 1094km were covered by 11 lines. These data are archived by BGS. Technical details of the survey are contained in an Acquisition Report.

  • This BIRPS deep profile survey took place in September 1991 off Cape Verde aboard the Bin Hai. The layout of the profiles consisted of two lines parallel to the spreading axis and nine lines perpendicular to the axis. The line spacing was 4 km so that structure within the oceanic basement could be mapped in three dimensions.

  • This British Geological Survey (BGS) marine geophysical and multibeam survey took place in July 2005 in the Summer Isles region and Loch Broom and Little Loch Broom aboard the RV Calanus. The survey was a part of the BGS Offshore Mapping and Modelling Project, North Atlantic Correlation. Subsurface seismic data were gathered using a Surface Tow Boomer. Multibeam bathymetry data was collected using a Geoacoustics GeoSwath system supplied and operated by Fathoms Ltd. All of the data were recorded digitally, but paper records were generated also. The data are archived by BGS. Backscatter and geophysical data are available for download. Technical details of the survey are contained in BGS Report IR/05/139 (http://nora.nerc.ac.uk/id/eprint/11140/).

  • 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 marine multibeam and geophysical survey took place in June 2011 in the Ardmucknish Bay area on board the BGS survey vessel RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) in collaboration with Scottish Association for Marine Science (SAMS) and National Oceanography Centre (SAMS). QICS (Quantifying and monitoring potential ecosystem impacts of geological carbon storage) was a scientific research project funded by NERC. The purpose was to collect the data necessary to identify a potential directional drilling route from shore to a submerged gas release point. Sea floor bathymetry data were collected using an EM3002D. Sub bottom seismic profiling data were collected using a surface tow boomer. These data are archived by BGS. Upon completion of the QICS study area additional seismic profiles were collected in the neighbourhood. Technical details of the survey are contained in BGS Report of Survey.

  • This British Geological Survey (BGS) marine multibeam, geophysical and sampling survey took place in April/May 2013 onboard the RRS James Cook. Data was collected from the North-Western Approaches area, incorporating the Sea of the Hebrides, Malin Sea and North Channel region, and extending landwards into sea lochs, including Loch Linnhe and Loch Scavaig. Sea-bed samples were collected using 15m rock drill, vibrocorer and piston corer. Sub-bottom seismic profiling data were gathered using the SBP120 installed in the RRS James Cook. MSCL data was measured by the University of Leicester. Most of the acoustic data were recorded digitally, but paper records were generated also. In additional to the initial work plan, a multibeam bathymetry dataset was acquired from the Sound of Kilbrannan. All the samples are archived by BGS except six piston core working halves were taken by Scottish Association for Marine Science (SAMS) for further study. Technical details of the survey are contained in the BGS Report of Survey.
