RV CIRLANA 01/1999 High-Resolution CTD Profiles from the European Shelf

Research vessel CIRLANA collected this oceanographic data in January 1999 using a lowered CTD rosette system. The data likely contains high-resolution vertical profiles of pressure, temperature, and conductivity from the European Shelf and Iberian Abyssal Plain. The Government Digital Service archives these measurements, which were originally collected by CEFAS for calibration and environmental study.

Use Cases

• Calculate salinity from conductivity data based on the UNESCO 1978/1983 formulations mentioned in the description
• Analyze vertical ocean structure based on the clean down-cast profile data collected from surface to sea bed
• Study temporal changes in marine parameters by comparing this 1999 data with later cruises described
• Calibrate satellite or model data using the in-situ bottle sample calibration methodology described

Strengths

• Data was collected using a professional lowered CTD rosette system, suggesting high instrument quality
• The description specifies coverage of the European Shelf and the Iberian Abyssal Plain
• Methodology includes water sample collection for calibration, which can improve data accuracy

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 vary between cruises, as noted in the description
