This geophysical and multibeam survey took place in March/April 2006 in the Bristol Channel on board the MV Confidante. It was carried out by Gardline under contract to British Geological Survey (BGS) and Geotek Ltd. It was co-funded by UK Department of Trade and Industry for their Strategic Environmental Assessment Programme (SEA8) and NERC/BGS for their marine mapping programme. The objective was to collect data for investigations of sediment mobility and for monitoring sea bed morphology and sea bed sediment texture. Seafloor bathymetry data were collected using an EM3000 multibeam system and Edgetech 4200FS sidescan sonar. Sub-bottom seismic profiling data were collected using a surface tow boomer. These data were recorded digitally and are archived by BGS. Technical details of the survey are contained in Gardline Report 6749, the BGS cruise report and preliminary geological interpretation are contained in BGS Report CR/06/085.

This DTI commissioned marine sampling survey took place as 2 legs in July/August/September 2000 in the area north and west of Shetland and Fladen Ground in the North Sea on board th RRS Charles Darwin. The primary purpose being to establish a regional description of the current state of the seabed in the White Zone. The project was led by Southampton Oceanographic Centre, sub-contracted by Geotek Ltd on behalf of the Department of Trade and Industry. This cruise was part of a continuing programme of environmental monitoring in these areas carried out as part of the Atlantic Frontier Environmental Network (AFEN) project. The primary sampling tool was a Bowers and Connelly Megacorer but a USNEL-type Boxcorer, Day Grab and 3m gravity corer were also used. A British Geological Survey geologist was onboard to undertake geological descriptions, the data from which is archived at BGS. For any other data from this survey contact National Oceanography Centre. Technical details of the survey are contained in BGS Internal Reports IR/01/135 and IR/01/079, Commissioned Report CR/01/43 and NOC Cruise Report No. 20 (http://nora.nerc.ac.uk/id/eprint/148424/).

This sampling (drilling) survey has been carried out by, contractors for Department of Energy, the survey took place from July to October 1977 in the SW Approaches and western English Channel on board the semisubmersible drilling rig Zephyr I. The purpose was to drill four stratigraphical test boreholes, Institute of Geological Sciences (IGS) now British Geological Survey (BGS) staff carried out well-site geologist duties. Borehole data were collected using drilling techniques. These data are archived by BGS. Details of the survey are contained in IGS Annual Report 1974.

This sampling and geophysical survey has been carried out by, contractors for Department of Trade and industry Strategic Environmental Assessment project (SEA4), the survey took place from July to August 2002 in the Faeroe-Shetland Channel on board the RV Kommandor Jack. The purpose was to collect data as part of an Environmental Assessment project. Sea floor data were collected using EM120 multibeam and backscatter data. Sample data were collected using Megacorer, box corer, gravity corer and Day grab. These data were recorded digitally and are archived by BGS. Technical details of the survey are contained in SEAS reports, see the Offshore GeoIndex SEA layers and the SEA Portal https://www.bgs.ac.uk/data/sea/app/search.

This sampling survey has been co-ordinated by, Hartley Anderson Ltd for Department of Trade and industry Strategic Environmental Assessment project (SEA2) the survey took place in May 2001 in the North Sea, Dogger Bank on board the RV Kommandor Jack. The purpose was to collect data as part of Strategic Environmental Assessment project (SEA2). Sample data were collected using Corer and grab sampling equipment. These data were recorded are archived by BGS.
