Marine bedrock dataset (DiGRock250k) version 3

DiGRock250k is a digital geological map showing the distribution of bedrock types in the UK Continental Shelf (UKCS) area, representing the natural continuation of the onshore bedrock geology into the offshore. The bedrock divisions on the map represent the principal lithostratigraphical units (e.g. formations and groups) in the UK, ranging in age from Proterozoic to Cainozoic in age, as defined in the BGS Lexicon of Named Rock Units. This dataset can be used in conjunction with other BGS offshore datasets that include: DiGSBS250k (Sea-Bed Sediments), DiGBath250k (Bathymetry) and the DiGHardSubstrate250k datasets. The bedrock geology below the sea-bed is 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.

Statement
The offshore bedrock geology was mapped using a range of remotely sensed (e.g. seismic, bathymetry) and physical ground truthing data (e.g. rock drills, cores ). This mapping was first published in printed form on the bedrock offshore 1:250 000 map series (Universal Transverse Mercator projection series maps, each sheet covering an area of 1 degree of latitude by 2 degrees of longitude; 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 the DiGRock250k digital map. This digital map has been put through a further checking and updating cycle in 2013 to produce the newly released DiGRock250k.
