Statement

The offshore bedrock geology was mapped using a range of remotely sensed (e.g. seismic, side scan sonar) and physical ground truthing data (e.g. boreholes, cores). This mapping was first published in printed form on the bedrock offshore 1:250 000 map series (known as Solid Geology). Using Universal Transverse Mercator projection, each sheet covers an area of 1 degree of latitude by 2 degrees of longitude. The printed maps are still available via the BGS Bookshop. The geological linework used to create the paper maps was used as the basis for the first version of this dataset (then call DiGRock250k). The second version of this dataset was released in 2007 (known as DiGRock250k v.2). The principle objective of this revision and geological checking was to remove, as much as possible, join-up issues between the various ‘sheet’ areas, inherited from the sequentially published paper maps. In 2013, the dataset was put through a further comprehensive geological and GIS checking process to create the third and current version (then named DiGRock250k v.3).
