RV CIRLANA 08/1989: Low-Resolution CTD Data from the European Shelf

Conductivity, temperature, and depth (CTD) data were collected from CEFAS research vessel cruises. The data broadly cover the European Shelf and the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The data were collected by the Government Digital Service, with profiles taken from the surface to near the sea bed.

Use Cases

• Calculate ocean salinity based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze vertical water column profiles based on pressure (depth), temperature, and conductivity measurements.
• Study temporal changes in marine environments based on data from specific research cruises.
• Calibrate sensor readings based on water samples collected from bottles fired on the up cast.

Strengths

• Data collection follows a standardized methodology using a lowered CTD rosette system.
• Coverage includes the European Shelf and the Iberian Abyssal Plain, providing regional context.

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.
• Last update date is unknown; freshness unverified.

Provenance

Source
