RV CIRLANA 01/1999 Low-Resolution CTD Data from the European Shelf

CEFAS research surveys collected this oceanographic data using a lowered CTD rosette system while vessels were stationary. The data broadly covers the European Shelf and the Iberian Abyssal Plain, with profiles from the surface to near the seabed. Early years collected a limited set of parameters like pressure, temperature, and conductivity, while later surveys added sensors for fluorometry and light measurement.

Use Cases

• Calculate seawater salinity based on conductivity measurements using UNESCO formulations.
• Analyze vertical ocean profiles for temperature and pressure data from specific stations.
• Calibrate biological or optical sensors using bottle sample data collected on the up cast.
• Study water mass properties across the European Shelf and Iberian Abyssal Plain.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system.
• Description indicates coverage of a specific geographic area: the European Shelf and Iberian Abyssal Plain.
• The data includes core physical oceanography parameters: pressure (depth), temperature, and conductivity.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
