BGS Seabed Sediments 250k version 3.0
The BGS Seabed Sediments 250k dataset is vector data is vector data which reflects the distribution of seabed substrate types 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 seabed is commonly covered by sediments that form a veneer or thicker superficial layer of unconsolidated material above the bedrock. These sediments are classified based on their grain size reflecting the environment in which were deposited. This information is important to a range of stakeholders, including marine habitat mappers, marine spatial planners, offshore industries (in particular, the dredging and aggregate industries). This dataset was primarily based on seabed grab samples of the top 0.1 m, combined with cores, dredge samples and sidescan sonar acquired during mapping surveys since the early 1970s. The variations in data density will be reflected in the detail of the mapping.

Data Quality
The original version of Seabed Sediments at 1:250 000 scale dataset (then known as DiGSBS250k) was digitised from the scanned version of the hard copy,1:250 000 scale offshore geological maps series. Sheets of these series were issued on a regular grid, with each map sheet covering an area of one degree of latitude by two degrees of longitude. Details of the printed map sheet names, numbers and publication dates are available from the BGS online catalogue and the printed maps are still available via the BGS Bookshop. The second version of this dataset was released in 2007 (named at the time DiGSBS250k v.2). The principal objective of this revision was to improve the positional accuracy of the data in the dataset. The third and current version of the Seabed Sediments at 1:250 000 scale dataset was released in 2011 (named as DiGRock250k v.3). This version has been updated using new PSA samples and multibeam data to directly modify the digital version.
