UK North Sea Seabed Environmental Survey Database

472 survey reports document biological, chemical, and locational data from approximately 520 seabed surveys commissioned by UK North Sea offshore oil operators. The UKOOA review compiled an inventory and database covering work from 29 contractors, agencies, and universities between 1975 and 1998. 203,945 records were exported to the NBN Gateway in October 2004 after data cleaning.

Use Cases

• Analyze trends in benthic biota composition and abundance from biological survey data over the 23-year period.
• Correlate chemical contamination levels with proximity to offshore oil and gas extraction and production (E&P) sites using locational data.
• Assess the spatial and temporal extent of environmental impact documented across the 472 survey reports.

Strengths

• Substantial temporal coverage spanning 23 years from 1975 to 1998.
• Aggregates data from an estimated 520 surveys conducted by 29 different organizations.
• Database contains 203,945 individual records exported for distribution.

Limitations

• Data is historical, with the last recorded surveys from 1998, limiting contemporary analysis.
• Data quality is variable, as acknowledged by the required cleaning of compiled records.
• Specific column names and data schema for the 203,945 records are not provided in the description.
