RV CIRLANA 05/1995 High Resolution CTD Data from the European Shelf

May 1995 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, collected using a lowered rosette system. Data was gathered from surface to near-sea-bed profiles, with water samples taken for calibration.

Use Cases

• Calculate ocean salinity based on conductivity measurements using UNESCO 1978/1983 formulations.
• Analyze vertical water column profiles based on pressure (depth), temperature, and conductivity data.
• Study temporal changes in marine parameters by comparing this 1995 cruise data with later surveys.
• Calibrate or validate ocean models using the high-resolution, station-based profile data.

Strengths

• Data is described as high-resolution, suggesting detailed vertical sampling.
• Covers a specific geographic area: the European Shelf and Iberian Abyssal Plain.
• Collected using a standardized lowered CTD rosette system, which is a common oceanographic method.

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, as noted in the description.
