RV CORYSTES 13/1994: Low-Resolution CTD Data from the European Shelf

The European Shelf and Iberian Abyssal Plain are covered by this data, collected from CEFAS research cruises. It contains profiles of pressure, temperature, and conductivity, with later cruises adding parameters like fluorescence and light measurements. The data was gathered using a lowered CTD rosette system from research vessels while on station.

Use Cases

• Calculate ocean salinity based on conductivity data using UNESCO formulations.
• Analyze vertical water column profiles based on pressure (depth), temperature, and conductivity data.
• Study phytoplankton biomass distribution based on fluorometer data mentioned for later cruises.
• Investigate water clarity or sediment load based on optical backscatter or transmissometer data.

Strengths

• Data collection methodology is explicitly described as using a lowered CTD rosette system for clean down-cast profiles.
• The description notes an expansion of measured parameters over time, including fluorometers and light sensors.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The exact sensor configuration and data format vary between cruises, requiring inspection.
