RV CORYSTES 13/1994 High Resolution CTD Data from the European Shelf

European Shelf and Iberian Abyssal Plain oceanographic data collected by CEFAS research vessels using a lowered CTD rosette system. The data includes core parameters like pressure, temperature, and conductivity, with later cruises adding sensors for fluorometry and optical backscatter. Data collection involves stationary vessel profiles from surface to sea bed, with calibration samples taken via water bottles.

Use Cases

• Calculate water salinity based on conductivity data using UNESCO formulations.
• Model vertical oceanographic profiles based on high-resolution downcast pressure and temperature data.
• Analyze phytoplankton biomass distribution based on fluorometer sensor data mentioned in the description.
• Study sediment transport or water clarity using optical backscatter or transmissometer data.

Strengths

• Data collection follows a standardized methodology using a lowered CTD rosette system for clean profiles.
• Core parameters like pressure, temperature, and conductivity are consistently measured, enabling salinity derivation.
• Description indicates expansion of measured parameters over time to include fluorometers and optical sensors.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics and exact sensor configuration must be inferred after download.
• Last update date is unknown; freshness unverified.
