    This sampling and geophysical survey has been carried out by, Institute of Geological Sciences (IGS) now British Geological Survey (BGS) in collaboration with other organisations for BGS, the survey took place in November 1974 in the area east of Shetland Islands on board the RRS Challenger. The purpose was to carry out trials of cable-controlled drilling submersible Consub and collect geophysical data for identification of potential drill sites. 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 1974.

    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 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 British Geological Survey (BGS) marine geophysical survey took place in October 1999 in the Mersey Estuary aboard the Environment Agency vessel Goastal Guardian. The purpose was to gather data which could be used in Coastal and Estuary Evolution studies. Sea-floor data were collected using an echosounder and a sidescan sonar. Subsurface seismic data were gathered using a surface tow boomer. These data are archived by BGS. Technical details of the survey are contained in BGS report WB/00/02.

    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).

    The JNCC marine survey took place in May 2008 within the Submarine structures in the mid-Irish Sea Area of Search (AoS) and the Solan Bank AoS on board the RV CEFAS Endeavour. The aim was identifying habitats listed under Annex I of the EC Habitats Directive; primarily Submarine structures made by leaking gases in the former AoS and Reef habitat in the latter. Multibeam bathymetry was collected using a Kongsberg EM3000D system and sidescan sonar data which was collected using a Benthos SIS 1624 sidescan sonar. Ground-truthing techniques included towed & drop down video/stills and Hamon grab sampling. Rock dredge sampling was also used on a few stations to gather samples of epibiota from hard substrata to assist with the taxonomic ID of the video & still images. The geology and geophysics component of the data are archived at the British Geological Survey (BGS) MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Biological and bathymetry data are archived at DASSH and UKHO respectively. For more information see http://jncc.defra.gov.uk/page-4732. Technical details of the survey are contained in JNCC report No. 430, http://jncc.defra.gov.uk/page-5347 and BGS subsample analysis report CR/09/51. JNCC Contract No: F90-01-1200.

    This geophysical survey has been carried out by Marine Geophysics Unit of British Geological Survey (BGS) for BGS, the survey took place from August to September 1971 in the Sea of the Hebrides area, on board the MV Surveyor. The purpose was to collect data as part of a regional mapping programme. Sea floor data were collected using Transit sonar. In September trials were carried out with a sea bed scintillation probe (SBSP), but no records available. These data are archived by BGS. No survey report currently available.

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.

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 adds to the data collected on a previous survey in 2003 and multibeam products include data from the 2003 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.

    This JNCC marine survey took place in July 2009 and surveyed two areas (Anton Dohrn seamount and East Rockall Bank Reef) for offshore Special Areas of Conservation (SACs). These areas are both now pSACs. The survey was commissioned by JNCC and undertaken by the British Geological Survey, University of Plymouth and Marin Mättenik AB. The aim was to enable the distribution, extent and biological characterisation of Annex I reef. Sidescan sonar data was acquired using a MMT AB EdgeTech 2200-MP, Multibeam bathymetry data were collected using a Kongsberg EM710, a Seatronics Drop Frame Camera System was used for digital photography and video. The geology and geophysics component of the data are archived at the British Geological Survey (BGS) MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Biological and bathymetry data are archived at DASSH and UKHO respectively. For more information see http://jncc.defra.gov.uk/page-5026. Technical details of the survey are contained in BGS Commercial Report CR/09/113 (http://nora.nerc.ac.uk/id/eprint/511601/), http://jncc.defra.gov.uk/PDF/2009_3_JNCC_Cruise_Report_Public%20(2).pdf.

    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.
