RV CIRLANA 02/1993: High-Resolution Ocean CTD Profiles from the European Shelf

European Shelf and Iberian Abyssal Plain oceanographic data collected by CEFAS research vessels. The dataset contains high-resolution Conductivity-Temperature-Depth (CTD) profiles from lowered rosette systems, with parameters including pressure, temperature, and conductivity for calculating salinity. Data collection methods involve stationary vessel profiles from surface to near seabed, with water samples taken for calibration on the up cast.

Use Cases

• Calculate ocean salinity profiles based on conductivity and temperature data.
• Analyze vertical water column structure based on high-resolution CTD profiles from surface to seabed.
• Calibrate oceanographic sensors using water sample data mentioned in the collection method.
• Study temporal changes in marine parameters on the European Shelf.

Strengths

• Data collection uses a lowered CTD rosette system, which suggests high-resolution vertical profiles.
• Water samples were taken for calibration, which likely improves data accuracy for core parameters.
• Coverage includes the European Shelf and the Iberian Abyssal Plain, providing a specific geographic focus.

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 varies between cruises, which may affect data consistency.
