RV CIRLANA 01/2001: Low-Resolution CTD Oceanographic Profiles from the European Shelf

Oceanographic profiles collected by CEFAS research vessels on the European Shelf and Iberian Abyssal Plain. Data was gathered using a lowered CTD rosette system while vessels were stationary, with water samples taken for calibration. The dataset likely contains core parameters like pressure, temperature, and conductivity, with later years including additional sensors for fluorometry and light measurement.

Use Cases

• Modeling seawater density and salinity based on conductivity, temperature, and pressure data.
• Analyzing vertical water column structure from surface-to-sea-bed profiles.
• Calibrating satellite-derived ocean data using in-situ conductivity and temperature measurements.
• Studying phytoplankton distribution patterns based on fluorescence sensor data mentioned in the description.

Strengths

• Data collection follows a standardized method using a lowered CTD rosette system.
• Includes calibration via water samples taken at specific depths.
• Covers a defined geographic area: the European Shelf and Iberian Abyssal Plain.

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, affecting data format consistency.
