Cefas Site Z: Marine Sediment Contaminant and Particle Size Data from Liverpool Bay, 2015

Sediment samples from 20 stations within and surrounding the Site Z dredged material disposal site in Liverpool Bay. The dataset likely contains particle size analysis (PSA), carbon content, and contaminant measurements for samples collected in September 2015. The data was published by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) via the Government Digital Service.

Use Cases

• Analyze sediment contamination levels based on contaminant measurements mentioned in the description
• Model particle size distribution in a disposal site based on sediment PSA data
• Assess carbon content in marine sediments for environmental baselines
• Monitor spatial variation of sediment properties around a designated disposal area

Strengths

• Samples collected from 20 specific stations, providing spatial coverage
• Data focuses on a single, well-defined disposal site (Site Z) and time period (September 2015)
• Includes multiple sediment analysis types (PSA, carbon, contaminants) per sample

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
