The European Shelf and Iberian Abyssal Plain are covered by this hydrographic data collected from CEFAS research cruises. Data was gathered using a lowered CTD rosette system while vessels were stationary, with water samples taken for calibration. The exact parameters measured vary by cruise but likely include pressure, temperature, conductivity, and later additions like fluorometers and light sensors.
Use Cases
- Calculate water salinity based on conductivity measurements using UNESCO formulations.
- Analyze vertical profiles of temperature and pressure to understand ocean stratification.
- Study phytoplankton biomass distribution using fluorometer data mentioned in the description.
- Investigate water clarity or particle load using optical backscatter or transmissometer data.
- Calibrate sensor readings using water samples collected on the up-cast.
Strengths
- Data collection follows a standardized method using a lowered CTD rosette system.
- The description specifies calibration via water samples taken at particular depths.
- Coverage includes the European Shelf and the Iberian Abyssal Plain.
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.
