Research vessel data collected by CEFAS (or DFR) broadly covers the European Shelf and the Iberian Abyssal Plain. Data were collected using a lowered CTD rosette system while the vessel was stationary, with water samples taken for calibration. The exact sensor configuration, which can include fluorometers and optical sensors, varies between cruises.
Use Cases
- Calculate water salinity based on conductivity measurements using UNESCO formulations.
- Analyze vertical profiles of temperature and pressure from surface to sea bed.
- Study chlorophyll distribution or water clarity based on fluorometer and transmissometer data.
- Calibrate sensor readings using water samples collected from specific depths.
Strengths
- Data collection uses a standardized lowered CTD rosette system for clean down-cast profiles.
- Water samples are taken for calibration, which likely improves data accuracy.
- Coverage includes the European Shelf and the Iberian Abyssal Plain.
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.
