Regional Geological Maps for the East Irish Sea and Cardigan Bay

A set of regional geological maps for the Cardigan Bay and East Irish Sea, produced by the North Sea Transition Authority and Lloyd's Register. The maps represent deliverables from a 3-year contract to produce maps and databases for the UK Continental Shelf. The data is public domain and was published as part of the NSTA's 2018/19 Activity Plan.

Use Cases

• Analyze subsurface structure based on depth structure maps mentioned in the description
• Study sediment thickness and deposition based on isochore maps mentioned in the description
• Identify geological features and basins based on structural elements maps mentioned in the description
• Model reservoir distribution based on reservoir distribution maps mentioned in the description
• Interpret paleoenvironments based on depositional facies maps mentioned in the description

Strengths

• Data is public domain, facilitating open access and reuse
• Maps are produced for main geological time intervals (e.g., Paleocene, Lower Cretaceous, Upper Jurassic)
• Project benefited from additional third-party data sources including CGG's Target database and BGS's Offshore Geoindex

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific UK offshore regions covered
