RV CIRLANA 06/1989 Low-Resolution CTD Data from the European Shelf

Oceanographic conductivity-temperature-depth (CTD) data collected from CEFAS research vessel cruises. The data broadly covers the European Shelf and the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The dataset likely contains profiles from the surface to near the sea bed, with parameters such as pressure, temperature, and conductivity, from which salinity can be calculated.

Use Cases

• Calculate ocean salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical water column structure based on CTD profile data from surface to sea bed.
• Calibrate sensor readings using water sample data collected from bottles fired on the up cast.
• Study temporal changes in shelf sea properties by comparing data from different cruises.

Strengths

• Data collection follows a standardized method using a lowered CTD rosette system on research vessels.
• Coverage includes the European Shelf and the Iberian Abyssal Plain, providing regional context.
• Description specifies the use of UNESCO formulations for calculating salinity from conductivity.

Limitations

• Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• The exact sensor configuration and data parameters vary between cruises, requiring manual inspection.
