The JNCC marine survey was undertaken by CEFAS in April 2008 in the Dogger Bank area North Sea onboard the Cefas Endeavour. This work was in support of JNCC’s requirement to recommend sites for designation as Special Areas of Conservation (SACs) to UK Government, under the EC Habitats Directive. The aim was further developing methodologies for identifying and defining the extent of Annex I shallow sandbank habitat and to conduct new habitat mapping surveys to further develop and integrate geomorphological and biological survey methods and strategies to provide interpreted information in GIS for use in site designation and management of activities in the Dogger bank area. Multibeam bathymetry data were collected using a Kongsberg EM3000D and sidescan sonar data were collected using a Benthos SIS 1624. Groundtruthing techniques including video tows, Hamon grab sampling and beam trawling. 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-4733, JNCC Report 429, available at http://jncc.defra.gov.uk/page-5076. Technical details of the survey are contained in CEFAS Cruise Report CEND 07/08.
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.
