  • Folk map using modified MESH Folk classes, Area Belgian continental shelf, Physical DEF

  • Exploratory survey around spoil disposal site due west of Swanage Bay, in anticipation of increased usage. Area approx 7.5 x 3.5 km. Multibeam survey in 5 corridors, each ~400m wide. Ground truthing at 6 stations by video (drop-camera). Survey area polygonised into 7 acoustically distinct areas, based on interpretation of multibeam backscatter and bathymetry. Habitat/biotope classification not attempted.

  • Area West Coast, potential future marine nature reserve close to the coast; together with other datasets (identical lui), full-coverage habitat maps were obtained; data has been verified; expert data collection

  • The shapefile senseco1 divides the Dutch part of the North Sea in 9 ecotope classes, varying from shallow coarse sand up to gravel. No class boundaries are given just descriptions. More details are given in the report.

  • A series of twelve marine inlets on the East Anglian and north Kent coasts (MNCR sector 6) have been studied as part of the Marine Nature Conservation Review programme. Comparable data from other organisations have been added to provide information on over 460 sites within the twelve inlets and analysed to classify the biotopes present.

  • Broad scale biotope types along Wexford coast mapped out to the 5 km limit

  • The survey of the marine environment in the Sound of Arisaig proposed SAC was undertaken by the BioMar Project, at the University of Newcastle, under contract to SNH. The Sound of Arisaig has an unusually high diversity of sublittoral sediment habitats within a relatively small area, and has rich maerl beds. This study was to map the pSAC and undertake further detailed studies of the maerl beds. Acoustic techniques were used validated by biological sampling using towed video and scuba divers. The data was stored and analysed using GIS.

  • This dataset is a map of the saltmarsh habitats in the Duddon Estuary

  • The shapefile ncp_eunis4 represents an ecotope-classification of the Dutch part of the North Sea. Assembling the 9 classes of the shapefile senceco1 into 5. The result, combining sediment and bathymetry, represents EUNIS classification level 4. More details are given in the report.

  • Mosselbanken volgens Dijkema Dijkema et al, 1989; Dijkema, 1991 Mosdijk is a shapefile of the mussel beds in the Dutch Wadden Sea. The beds are digitised from aerial photos taken over the period 1968 and 1976, and are validated with a groundtruth in 1989.
