Research vessel surveys by CEFAS collected conductivity-temperature-depth (CTD) profiles from the European Shelf and Iberian Abyssal Plain. The lowered CTD rosette system captured data from the surface to near the seabed, with parameters including pressure, temperature, and conductivity. In later years, sensors for fluorometers, optical back scatter, transmissometers, and light (PAR) were added.
Use Cases
- Calculate salinity profiles based on conductivity data using UNESCO formulations.
- Analyze vertical structure of the water column based on pressure (depth) and temperature profiles.
- Study biogeochemical indicators based on fluorometer and optical back scatter sensor data.
- Calibrate sensor readings based on water samples collected from bottles fired at specific depths.
Strengths
- Data collection follows a standardized methodology using a lowered CTD rosette system.
- The description specifies core parameters collected: Pressure (Depth), Temperature, and Conductivity.
- Later surveys expanded the parameter set to include fluorometers and optical sensors.
Limitations
- Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
- The exact sensor configuration varies between cruises, which may affect data consistency.
- Last update date is unknown; freshness unverified.
