NSTA and Lloyd's Register SW Approaches Regional Geological Maps

A 2018/19 project by the North Sea Transition Authority and Lloyd's Register produced regional geological maps for the UK Continental Shelf. This fourth set covers the SW Approaches and Anglo Paris Basin, including depth structure, isochore, and subcrop/supercrop maps for major geological intervals. The data is public domain and incorporates third-party sources like BGS, Getech, CGG, and TGS.

Use Cases

• Modeling subsurface depth structure based on regional geological time intervals.
• Analyzing sediment thickness and distribution using isochore maps.
• Interpreting geological history and erosion patterns from subcrop and supercrop maps.

Strengths

• Maps are produced for major geological time intervals like Paleocene and Upper Jurassic.
• Project integrates multiple third-party data sources including BGS, Getech, and CGG.
• Data is released as public domain.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
