BGS Offshore Bedrock 250k version 3.0
The BGS Offshore Bedrock 250k dataset is vector data which reflects the offshore bedrock geological of the UK and some of its adjacent waters at 1:250,000 scale. This comprehensive product provides a digital compilation of the paper maps published by BGS at the same scale, as well as, additional re-interpretations from regional geological studies. The composition, age and deformational history of the rocks underlying the seabed (bedrock) are important for a range of stakeholders, including marine spatial planners and offshore developers. The dataset is arranged in two GIS layers: Bedrock Lithostratigraphy and Bedrock Structural Geology. The polygons within the Bedrock Lithostratigraphy layer show the spatial distribution of the principal lithostratigraphical units (formations and groups). The lines within the Structural Geology layer show the location and extent of known structural features such as faults and folds. This broadscale dataset was derived from geophysical data (e.g. airgun, boomer, sparker, sidescan sonar, magnetometer, gravity meter) and data obtained from commercial wells and BGS shallow boreholes. The variations in data density will be reflected in the detail of the mapping.

Data Quality
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).
