RV CIRLANA 06/1999: High-Resolution Ocean CTD Profiles from the European Shelf

June 1999 oceanographic data collected by CEFAS from the RV CIRLANA research cruise. The dataset contains high-resolution Conductivity-Temperature-Depth (CTD) profiles from the European Shelf and Iberian Abyssal Plain, gathered using a lowered CTD rosette system while the vessel was stationary. Water samples for calibration were taken via bottles fired at specific depths during the up cast.

Use Cases

• Calculate water salinity based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze vertical profiles of temperature and pressure (depth) from the surface to near the sea bed.
• Calibrate sensor readings using the water bottle samples collected on the up cast.
• Study the spatial distribution of basic oceanographic parameters across the European Shelf.

Strengths

• Data is described as high-resolution, collected from a clean down cast profile.
• Covers a specific geographic area: the European Shelf and Iberian Abyssal Plain.
• Includes calibration samples from water bottles fired at particular depths.

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 and available parameters vary between cruises.
