Sea-bed sediments can only be mapped offshore, where the most recent deposits commonly form a veneer or superficial layer of unconsolidated material on the sea-bed. The dataset is produced for use at 1:250,000 scale. The boundaries between sediment classifications or types are delineated using sample station particle size analyses and descriptions, seafloor topography derived from shallow geophysical data and where available multibeam bathymetry and backscatter and side scan sonar profiles. The sediment types present on the sea-bed are of importance to a range of groups, including marine habitat mappers, marine spatial planners, the offshore construction and development sector, and the dredging and aggregate industries. These groups require detailed information on the nature of the sea-bed, including the sediment types present. The DiGSBS250k dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs. 250k_Sea_Bed_Sediments_LL84_Geology_Polygons_v3 20110101 Cooper,Rhys Mark BGS Edinburgh Project Leader Murchison House, West Mains Road Edinburgh EH9 3LA United Kingdom enquiries@bgs.ac.uk (0131) 6671000 BGS Spatial Data Sea floor sediments BGS Thesaurus of Geosciences 20010101 British Geological Survey Kingsley Dunham Centre Keyworth Nottinghamshire NG12 5GG United Kingdom enquiries@bgs.ac.uk (0115) 9363100 Thesauri 250000 Cooper,Rhys Mark BGS Edinburgh Project Leader (0131) 6671000 Murchison House, West Mains Road Edinburgh EH9 3LA United Kingdom enquiries@bgs.ac.uk ISO 19115 Geographic Information - Metadata BGS Version 2 dataset Verified GCS_WGS_1984 EPSG 7.4.1 0 0 20110325 Shapefile withheld 70.852 70.852 The Orignal version of DigSBS250k was digitised from the scanned from the hard copy,1:250 000 scale offshore geological maps.
