NSTA and Lloyd's Register East Irish Sea and Cardigan Bay Regional Geological Maps (ArcGIS

East Irish Sea and Cardigan Bay regional geological maps published by the North Sea Transition Authority as part of its 2018/19 Activity Plan. The maps represent the eighth set of deliverables from a three-year contract with Lloyd's Register to produce maps and databases for the UK Continental Shelf. The data is public domain and was last updated on 2026-06-18.

Use Cases

• Analyze regional geological structures for hydrocarbon potential based on the described maps and interpreted products.
• Integrate public domain geological data into GIS projects for the East Irish Sea and Cardigan Bay regions.
• Inform subsurface models using lithology curves derived from digital log data mentioned in the description.

Strengths

• Data is public domain, facilitating open access and reuse.
• Maps are part of a systematic three-year contract covering the whole UK Continental Shelf.
• Interpretation benefited from 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.
