RV CIRLANA 05/1985: Low-Resolution CTD Data from the European Shelf

The European Shelf and Iberian Abyssal Plain are covered by this oceanographic data. It was collected by CEFAS or DFR research vessels using a lowered CTD rosette system while the vessel was stationary on station. The data likely contains profiles of pressure, temperature, and conductivity, with salinity derivable from UNESCO formulations, and may include later sensor additions like fluorometers.

Use Cases

• Modeling salinity distributions based on conductivity and temperature data mentioned in the description.
• Analyzing vertical water column profiles from surface to sea bed based on the described collection method.
• Calibrating modern sensor data against historical CTD measurements from early research cruises.
• Studying temporal changes in basic oceanographic parameters on the European continental shelf.

Strengths

• Data collection method is explicitly described as using a lowered CTD rosette system for clean down-cast profiles.
• Scope is defined as broadly covering the European Shelf with some data from the Iberian Abyssal Plain.
• The description notes the potential inclusion of additional sensors like fluorometers in later years.

Limitations

• Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• The exact data parameters and configuration are noted to vary between cruises, requiring inspection.
