RV CORYSTES 1B/1994: Low-Resolution CTD Profiles from the European Shelf

Research vessel data collected by CEFAS (or DFR) using a lowered CTD rosette system while the vessel was stationary. The data broadly cover the European Shelf and include profiles from the surface to near the sea bed, with water samples taken for calibration on the up cast. Early years likely contain core parameters like pressure, temperature, and conductivity, from which salinity can be derived.

Use Cases

• Modeling water column stratification based on temperature and salinity profiles mentioned in the description
• Calibrating satellite-derived sea surface salinity data using in-situ conductivity measurements
• Studying spatial patterns of marine productivity using fluorometer or PAR (photosynthetically available radiation) sensor data
• Analyzing sediment transport or water clarity using optical backscatter or transmissometer readings

Strengths

• Data collected using a standardized lowered CTD rosette system, which typically provides high-quality downcast profiles
• Includes calibration samples from water bottles fired at specific depths
• Covers a broad geographic area including the European Shelf and the Iberian Abyssal Plain

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 varies between cruises, affecting data format and available parameters
