North Sea Sediment Organic Carbon Concentrations from Three Research Cruises

Concentration of organic carbon from CHN analysis of sediment samples collected by box core from sites in the North Sea during three Cefas cruises on RV Corystes (Cruise Codes CORY 10/2001, CORY 09/2002 and CORY 8x/2003). Cores were sliced into 1cm samples at a range of depths from 0-17cm. The data has been used to summarise profiles and describe spatial variance within four Ecohydrodynamic Units (EHUs).

Use Cases

• Modeling organic carbon sequestration in marine sediments based on depth profiles.
• Analyzing spatial variance of sediment composition within defined Ecohydrodynamic Units.
• Calibrating or validating biogeochemical models for the North Sea region.
• Studying the relationship between sediment depth and organic carbon concentration.

Strengths

• Data is derived from three dedicated research cruises, providing a systematic collection.
• Samples were sliced at 1cm intervals from 0-17cm, offering high vertical resolution.
• Analysis was performed using CHN analysis, a standard method for organic carbon measurement.

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.
