RV CIRLANA 06/1999 High Resolution CTD Data from the European Shelf

High-resolution Conductivity-Temperature-Depth (CTD) profiles collected from the CEFAS research vessel RV CIRLANA in June 1999. Data was gathered using a lowered CTD rosette system while the vessel was stationary, with water samples taken for calibration. The archive broadly covers the European Shelf, with some data extending to the Iberian Abyssal Plain.

Use Cases

• Calculate seawater salinity based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze vertical oceanographic profiles from the surface to near the sea bed.
• Calibrate sensor readings using water samples collected from bottles fired on the up cast.
• Study temporal changes in marine parameters by comparing with data from subsequent years with added sensors.

Strengths

• Data collection followed a standardized method using a lowered CTD rosette system for clean down-cast profiles.
• Description specifies coverage of the European Shelf and Iberian Abyssal Plain.
• Calibration was performed using water samples from bottles fired at specific 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.
