RV CIRLANA 06/1997 High-Resolution CTD Data from the European Shelf

High-resolution Conductivity-Temperature-Depth profiles collected from the CEFAS research vessel RV CIRLANA in June 1997. The data covers the European Shelf and Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The Government Digital Service provides this archive, which includes core parameters like pressure, temperature, and conductivity for calculating salinity.

Use Cases

• Calculate ocean salinity profiles based on conductivity and temperature data.
• Analyze vertical water column structure for the European Shelf based on CTD profiles.
• Calibrate satellite or model-derived sea surface temperature using in-situ measurements.
• Study marine biogeochemistry by integrating data from later sensors like fluorometers.

Strengths

• Data was collected using a standardized lowered CTD rosette system, which suggests methodological consistency.
• The description specifies coverage includes the European Shelf and the Iberian Abyssal Plain.
• Core parameters allow for salinity calculation using established UNESCO formulations.

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.
