  • 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 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.

  • Wessex Archaeology was commissioned by Historic Scotland to undertake a geophysical survey of the Designated Sites of the Blessing of Burntisland, HMS Campania: designated wreck sites located within the Firth of Forth, Scotland. The work was undertaken as part of the contract for Archaeological Services in Relation to the Protection of Wrecks Act (1973). Wessex Archaeology survey operations took place between 2nd and 6th August 2004. All surveying took place off the survey vessel owned and operated by St Andrews University. This is Crown Copyright Data collected and processed by Wessex Archaeology. The geophysical survey included the use of sidescan sonar and sub bottom profiler. 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 survey took place during August 2004 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 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. Technical details of the survey are contained in 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 survey has been carried out in May/June 2009 off the east coast of East Anglia on board the CEFAS Endeavour under contract for the Aggregate Levy Sustainability Fund (MALSF) comprising the acquisition of groundtruthing data including vibrocore samples, clamshell grab samples, mini-Hamon grab samples, 2m Jennings beam trawls and various camera techniques as part of a Regional Environmental Characterisation. The sample sites were chosen based on data acquired on the BGS 2008/04 / CEND 18/08 geophysical survey which took place from the 27th September to the 30th October 2008. Further geophysical data was acquired using a multibeam echosounder and dual frequency side scan sonar. The survey was undertaken in joint collaboration between the British Geological Survey, the Centre for Ecology, Fisheries and Aquaculture Science (CEFAS) and Wessex Archaeology. BGS Internal Report IR/10/019.

  • 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 British Geological Survey (BGS) regional marine geophysical and sampling survey took place in September-October 1971 in Lyme Bay on board the fishing vessel Dorset Lass. The purpose was to obtain more information on sediment transport and solid geology, carried out in conjunction with the Engineering Geology Unit. Sonar records were obtained from a KH MS.47 transit sonar. Seabed samples were collected by scuba divers. These data are archived by BGS. Summary details of the survey are contained in Institute Geological Sciences (IGS) Report 79/10.

  • 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).
