UK Offshore Sediment Disposal Volumes and Contaminants, 2000-2020

Data from 2000 to 2020 on registered offshore sediment disposal sites around the UK coast. The dataset includes volumes of disposed material, dredged areas, calculated contaminant levels, and licence details. The Centre for Environment, Fisheries and Aquaculture Science (Cefas) collated this data on behalf of Defra to meet UK obligations under international conventions.

Use Cases

• Modeling contaminant dispersion in marine environments based on disposal volumes and locations.
• Analyzing trends in dredging activity and sediment disposal over the 20-year period.
• Assessing compliance with environmental regulations based on reported licence details.
• Correlating dredged area measurements with estimated contaminant levels in the disposed material.

Strengths

• Covers a 20-year time range from 2000 to 2020.
• Includes multiple measured and calculated variables: volumes, areas, and contaminant levels.
• Reported by a government science agency (Cefas) for international treaty obligations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
