Nirex Digital Geoscience Database (NDGD) contains raw and processed digital data from geological investigations at the Sellafield site in western Cumbria. The data includes borehole-derived information on geology, geophysics, hydrology, and logistics collected between 1989 and 1997. It was compiled by the Nuclear Industry Radioactive Waste Executive and is now held by the British Geological Survey.
Use Cases
- Analyze borehole location and survey information to model subsurface geological structures at Sellafield.
- Integrate geological and geophysical borehole logs to characterize stratigraphy and lithology for site assessment.
- Use hydrological and hydrochemical borehole datasets to evaluate groundwater conditions and hydrogeological properties.
- Apply geotechnical borehole geology data for stability and suitability modeling of potential waste disposal sites.
Strengths
- Data originates from a focused, multi-year government-led investigation program from 1989 to 1997.
- Includes diverse data types: raw field measurements, laboratory analyses, and derived modeling outputs.
- Managed and provided by the authoritative British Geological Survey (BGS).
Limitations
- Dataset scope is limited to the Sellafield area in western Cumbria, not representative of other regions.
- Excludes some groundwater-related information from down-hole monitoring strings.
- Temporal coverage ends in 1997, lacking more recent measurements.
