NCEA Benthic Sediment Chemistry: Analysis Ready Data for English Waters (2023-2025)

The Natural Capital Ecosystem Assessment (NCEA) Benthic Sediment Chemistry network provides evidence on chemicals in estuarine and coastal sediments. This dataset contains chemical analysis results from sediment samples collected in English waters between 01 April 2023 and 31 March 2025, including supporting data like sampling locations. It is produced by the UK Environment Agency as part of Defra's largest R&D programme to inform water management.

Use Cases

• Assess chemical status of benthic sediments based on determinand analysis results mentioned in the description
• Map pollution sources and trends based on geospatial sampling location data
• Model the impact of chemical pressures on water environments to inform sustainable management
• Establish a baseline for natural capital assets in English coastal and estuarine areas

Strengths

• Data covers a defined two-year period from April 2023 to March 2025
• Includes geospatial context with sampling locations
• Produced by the authoritative Environment Agency under the UK Government's NCEA programme

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
