RV CIRLANA 06/1997 High-Resolution CTD Data from the European Shelf

CEFAS research cruise data collected using a lowered CTD rosette system from the RV CIRLANA in June 1997. The dataset contains high-resolution profiles of pressure, temperature, and conductivity from the surface to near the sea bed, covering the European Shelf and the Iberian Abyssal Plain. Salinity can be derived from conductivity using standard UNESCO formulations.

Use Cases

• Modeling water column stratification based on temperature and salinity profiles.
• Calibrating satellite-derived sea surface salinity data using in-situ conductivity measurements.
• Studying seasonal or regional hydrographic patterns on the European Shelf.
• Analyzing the relationship between physical parameters and biological activity, as the description mentions later cruises included fluorometers and PAR sensors.

Strengths

• Data is collected using a standard lowered CTD rosette system, which is a recognized method for high-quality profile data.
• The description specifies that down cast data should be a clean profile, suggesting controlled data collection.
• Coverage includes the European Shelf and the Iberian Abyssal Plain, providing a specific geographic scope.

Limitations

• Row count, file formats, and column-level documentation are unknown, which limits suitability assessment.
• The exact sensor configuration and available parameters for this specific June 1997 cruise are not detailed.
• Last update date and license information are unknown.
