RV CIRLANA 08/1991 Low-Resolution CTD Data from the European Shelf

Conductivity-Temperature-Depth (CTD) data collected from CEFAS research cruises on the European Shelf and Iberian Abyssal Plain. The data were gathered using a lowered CTD rosette system while vessels were stationary, with water samples taken for calibration. The dataset likely contains profiles from the surface to near the sea bed, with parameters such as pressure, temperature, and conductivity.

Use Cases

• Calculate salinity profiles based on conductivity and temperature data using UNESCO formulations.
• Analyze vertical ocean structure based on pressure (depth), temperature, and conductivity profiles.
• Calibrate sensor readings using water sample data collected from bottles fired at specific depths.
• Study temporal changes in marine environments by comparing data from different research cruises.

Strengths

• Data collection follows a standardized methodology using a lowered CTD rosette system.
• Coverage includes the European Shelf and the Iberian Abyssal Plain.
• The description indicates calibration was performed using water samples.

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.
