UKCS Seeps Database: Satellite-Mapped Hydrocarbon Seepage in the North Sea

983 individually interpreted satellite images form the UKCS Seeps Database, providing between 10x and 20x temporal coverage, with 20x coverage for most of the North Sea. The North Sea Transition Authority purchased CGG's NPA Satellite Mapping database for publication. The data was last updated on 2026-06-18.

Use Cases

• Monitor natural hydrocarbon seepage patterns based on satellite imagery interpretation.
• Analyze temporal changes in marine seepage activity based on the dataset's 10x to 20x temporal coverage.
• Support environmental baseline studies for the North Sea based on geospatial seep data.
• Validate geological models of subsurface hydrocarbon migration based on surface seepage observations.

Strengths

• Consists of 983 individually interpreted satellite images.
• Provides between 10x and 20x temporal coverage, with 20x for the majority of the North Sea.
• Sourced from CGG's established NPA Satellite Mapping methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update is in the future (2026-06-18).
