CP2 Regional Sea Boundaries: Western Channel & Celtic Sea, Offshore 1:250k: Bristol Channel, SeaVoX Sub-Ocean: BRISTOL CHANNEL
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. See the Offshore GeoIndex SEA layers and the SEA Portal https://www.bgs.ac.uk/data/sea/app/search.
For more detailed information on the acquisition equipment and data collection techniques, operational standards, data processing methods and quality control procedures used on this survey see the Report of Survey/Cruise Report and associated documentation where available. The information available may vary depending on the age of the survey. Data are checked and loaded to the BGS Coastal and Marine data management system following BGS marine data management procedures.
