RV Corystes 1997 High-Resolution CTD Profiles from the European Shelf

High-resolution Conductivity-Temperature-Depth (CTD) data were collected from the CEFAS research vessel RV Corystes in July 1997. The data broadly cover the European Shelf and the Iberian Abyssal Plain, with profiles taken from the surface to near the seabed. Water samples for calibration were collected using bottles fired on the up cast.

Use Cases

• Calculate salinity from conductivity and temperature based on the UNESCO 1978/1983 formulations mentioned in the description.
• Analyze vertical water column structure based on the high-resolution down cast profile data.
• Calibrate sensor readings using the water sample data collected on the up cast.
• Study spatial variability of oceanographic parameters across the European Shelf and Iberian Abyssal Plain.

Strengths

• Data were collected using a lowered CTD rosette system, which is a standard method for stationary vessel profiles.
• The down cast data is described as a clean profile, suggesting controlled data collection.
• The description specifies calibration via water samples, indicating a quality control process.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The exact sensor configuration and available parameters for this 1997 cruise are not detailed.
