RV CORYSTES 05/1999: Low-Resolution CTD Data from the European Shelf

Lowered CTD rosette system data collected from CEFAS research cruises on the European Shelf and Iberian Abyssal Plain. The data likely contains profiles of pressure, temperature, and conductivity, with salinity calculable using UNESCO formulations. The exact parameters vary by cruise, with later years adding sensors like fluorometers and optical backscatter.

Use Cases

• Calculate water salinity profiles based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze vertical ocean structure based on pressure (depth) and temperature profiles.
• Study phytoplankton biomass distribution based on fluorometer data mentioned for later cruises.
• Investigate water clarity or sediment load using optical backscatter or transmissometer data referenced in the description.

Strengths

• Data collected using a standardized lowered CTD rosette system for stationary vessel profiles.
• Description specifies core parameters: Pressure (Depth), Temperature, and Conductivity.
• Later cruises expanded sensor suites to include fluorometers and optical instruments.

Limitations

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