  • This marine geophysical survey of Beaufort's Dyke, North Channel took place in May 2008 aboard the RV Corystes. The British Geological Survey were invited to participate in the survey by AFBI (Agri-Food and Biosciences Institute). Subsequent additions to the AFBI programme allowed BGS to run seismic over the Pisces Reef in the northwest Irish Sea and off the Antrim coast. The purpose was to gather data which could be used to provide seismic profiling of features identified on the multibeam bathymetry data to aid interpretation. Three areas were surveyed and good quality data were collected in 35 survey tracks. Subsurface seismic data were gathered by using a sparker. The data were recorded digitally, but paper records were generated also. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report IR/08/38.

  • This British Geological Survey (BGS) marine geophysical and sampling survey took place in January 1973 in the Firth of Forth on board the Minto. Seabed samples were collected using Shipek grab and Gravity corer. Subsurface data were gathered trialling Pinger and Sparker instruments. These data are archived by BGS.

  • This marine geophysical survey took place from 05/07/92 – 06/07/92 in the area of the Barra Fan on board the RV Kommandor Michael. The survey was carried out by the British Geological Survey (BGS), Marine Biological Association and Dunstaffnage Marine Laboratory. The aim of the survey was to investigate the source and fate of methane in marine sediments. Sub bottom seismic profiling data were collected using a Deep Tow Boomer. These data are archived by BGS. Technical details are contained in BGS Report WB/92/27. Report: Dobinson, A. 1992. Barra Fan Project: Geophysical Operations Report - Project 92/02, https://nora.nerc.ac.uk/id/eprint/529922/.

  • 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 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 British Geological Survey (BGS) marine geophysical survey took place during October/November 2003 in the Outer Bristol Channel aboard the RV Prince Madog. Netsurvey Ltd were commissioned to provide multibeam services. This survey was undertaken for the Outer Bristol Channel Marine Habitat Study (OBCMHS) as part of a series of five surveys. The OBCMHS was principally funded by the Aggregate Levy Sustainability Fund, MALSF, (administered in Wales by the Welsh Assembly Government), the Sustainable Land Won and Marine Dredged Aggregate Minerals Programme of the Office of the Deputy Prime Minister (ODPM), administered by Mineral Industry Research Organisation (MIRO), with contributions from others. Sea floor data collected were high-resolution multibeam bathymetry and side-scan sonar (on selected lines). Subsurface data were gathered using a surface tow boomer (on selected lines). The multibeam data collected on this survey were later merged with data from the 2004 survey and this combined dataset is available with the 2004 survey. Most of the data were recorded digitally. Some paper records were also generated also. These data are archived with the MEDIN Data Archive Centres (DAC), including the BGS DAC for geology and geophysics and the UKHO DAC for bathymetry data. Technical details of the survey are contained in BGS Cruise report IR/04/012 (http://nora.nerc.ac.uk/id/eprint/509269/) and BGS Cruise report IR/05/082 (http://nora.nerc.ac.uk/id/eprint/11121/). For further information on the surveys and general information on the OBCMHS see the final report (Mackie et al, 2006. BIOMOR Reports 4:ISBN 0-7200-0569-8).

  • This British Geological Survey (BGS) marine geophysical survey took place in July 2013 approx 15km east of the island of Mingulay on board the RV Calanus. The purpose was to obtain seismic profiles across the coral mounds of the Mingulay Coldwater Coral Reef. An additional line was collected in Sound of Mull as a test. It has provided useful information on a submarine landslide. Sub bottom seismic profiling data were gathered by BGS using an Applied Acoustics surface tow boomer (S-Boom). These data are archived by BGS. Technical details of the survey are contained in BGS Report OR/13/033. GeoIndex Offshore - https://mapapps2.bgs.ac.uk/geoindex_offshore/home.html?cruise=2013/7&.

  • This marine geophysical survey undertaken by Institute of Geological Sciences (BGS) part funded by the Water Resources Board took place March to June 1972 in The Wash on board the fishing vessel Exact. Sea floor data were collected using a transit sonar. Subsurface data were gathered using a pinger, boomer and sparker , a total of 426.5 miles were covered. These data are archived by BGS. Technical details of the survey are contained in BGS Internal Report WB/ MG/72/ 45, details of Wash surveys contained in WB/MG/74/030 and IGS report 78/18.

  • 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 marine geophysical survey took place on 1st October 2014 in the area of Ardmucknish Bay on board the RV White Ribbon. The survey was carried out by the British Geological Survey (BGS). This was a follow up survey to the previous work carried out in this area (Surveys: 2011/4 and 2012/5, 2012/7) to monitor changes in the geometry of gas charged sediments. QICS (Quantifying and monitoring potential ecosystem impacts of geological carbon storage) was a scientific research project funded by NERC; its purpose was to improve the understanding of the sensitivities of the UK marine environment to a potential leak from a carbon capture storage (CCS) system. Sub bottom seismic profiling data were collected using an Applied Acoustics surface tow boomer (STB). These data are archived by BGS. Webpage www.bgs.ac.uk/QICS/. NERC grant NE/H013954/1.
