BGS Seabed Geology 10k
Seabed geology of the UK’s continental shelf, fine-scale maps providing detailed and accurate characterisation of the seabed geology, integrating substrate geology, structural geology and seabed geomorphology. Areas covered Anglesey, Bristol Channel, Dorset, East Anglia and Offshore Yorkshire. Mapping is based primarily on high-resolution bathymetry data produced by the UK Civil Hydrography Programme (CHP). Analysis and interpretation are further informed by secondary data and information resour

What's in it
- Data offered docs-verified
- substrate geology (bedrock and superficial units dominant within the top 1 m below seabed) · structural geology (principal faults and folds at rockhead and seabed) · seabed geomorphology (physical morphology and interpreted geomorphic character)
- Coverage docs-verified
- Anglesey, Bristol Channel, Dorset, East Anglia and Offshore Yorkshire
- Resolution docs-verified
- Mapped at a scale of 1:10 000; should not be used at finer scales
- Update frequency docs-verified
- irregular
- Formats docs-verified
- HTML
- Access docs-verified
- Public web access via data.gov.uk; copyright vested in NERC, so reproduction or transmission needs prior permission from BGS
Useful for
- Use cases llm-inferred
- Marine EIA desk study: regional seabed substrate and geomorphology context for nearshore schemes · Coastal outfall or cable route screening: regional seabed geology overview before site investigation · Coastal scheme baseline: seabed geomorphology context for the five mapped areas
- Audience llm-inferred
- marine and coastal engineers · environmental consultants · geologists · GIS analysts
Limitations
- Constraints docs-verified
- Not for local or site-specific geology; seabed sediments can move and expose or bury hard substrate · Mapped at 1:10 000 and should not be used at finer scales · Covers only five named areas · Update frequency is irregular · Copyright restricts reproduction without BGS permission · NERC/BGS gives no warranty on accuracy or suitability for any use
