RV Corystes 1993 High-Resolution CTD Profiles from the European Shelf

September 1993 data collected by CEFAS from the RV Corystes research vessel using a lowered CTD rosette system. The dataset contains high-resolution profiles of pressure, temperature, and conductivity from the European Shelf and Iberian Abyssal Plain, with salinity derivable from conductivity. Data collection involved stationary vessel profiles from surface to near seabed, with water samples taken for calibration.

Use Cases

• Calculate water salinity and density profiles based on the collected conductivity, temperature, and pressure data.
• Analyze vertical ocean structure and water mass properties based on the high-resolution CTD profiles.
• Calibrate satellite or model-derived oceanographic data based on the in-situ measurements.
• Study temporal changes in shelf sea conditions by comparing this 1993 data with later surveys.

Strengths

• Data collected using a standardized lowered CTD rosette system, which is a core oceanographic method.
• Profiles are described as 'clean' for the down cast, suggesting controlled data collection.
• Salinity can be calculated using established UNESCO 1978/1983 formulations mentioned in the description.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The exact sensor configuration and additional parameters like fluorometry vary by cruise and are not detailed for this specific dataset.
