RV Corystes 04/1988 Low-Resolution CTD Data from the European Shelf

European Shelf and Iberian Abyssal Plain oceanographic data collected by CEFAS research cruises. The data were gathered using a lowered CTD rosette system while the vessel was stationary, capturing profiles from the surface to near the seabed. The dataset likely contains core parameters such as pressure, temperature, and conductivity, with salinity derivable using UNESCO formulations.

Use Cases

• Calculate water salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical ocean structure based on downcast CTD profiles mentioned in the description.
• Calibrate sensor readings using water sample data collected from bottle firings.
• Study temporal changes in marine environments by comparing data from different cruises.

Strengths

• Data collection follows a standardized methodology using a lowered CTD rosette system.
• Geographic coverage includes the European Shelf and the Iberian Abyssal Plain.
• Core oceanographic parameters allow for the calculation of derived properties like salinity.

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.
