SEA1 Charles Darwin Cruise 123: Sediment Chemistry from the Faroe Shetland Channel (2000)

Sediment samples were collected during the Charles Darwin cruise 123 between July and September 2000 as part of the Strategic Environmental Assessment SEA1. The data analysis report includes measurements for total organic carbon and nitrogen, total hydrocarbons, n-alkanes, and polynuclear aromatic hydrocarbons (PAH). The dataset was produced for the UK Department of Trade and Industry (now Department of Energy and Climate Change) and is available via the Government Digital Service on an EU open data platform.

Use Cases

• Modeling baseline hydrocarbon contamination in marine sediments based on the reported PAH and n-alkane content.
• Assessing the relationship between sediment organic matter (carbon/nitrogen) and pollutant levels for environmental impact studies.
• Calibrating or validating remote sensing or geochemical models for the Faroe Shetland Channel region using the reported chemical analyses.

Strengths

• Data is associated with a formal government environmental assessment program (SEA1) and report (ERT Report R00/215).
• Analysis covers multiple specific chemical compounds, including 2 to 6 ring polynuclear aromatic hydrocarbons (PAH).
• Temporal and geographic scope is clearly defined as July-September 2000 in the Faroe Shetland Channel.

Limitations

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