Lowered CTD rosette system data collected from CEFAS research cruises on the European Shelf and Iberian Abyssal Plain. The data likely contains profiles of pressure, temperature, and conductivity, with salinity calculated using UNESCO formulations. In later years, additional sensors such as fluorometers and transmissometers were added, with the exact configuration varying by cruise.
Use Cases
- Modeling ocean salinity profiles based on conductivity and temperature data.
- Analyzing water column structure and stratification from surface-to-sea-bed profiles.
- Calibrating satellite-derived ocean data using in-situ CTD measurements.
- Studying temporal changes in marine environments from historical cruise data.
Strengths
- Data collection follows a standardized methodology using a lowered CTD rosette system.
- Coverage includes the European Shelf and extends to the Iberian Abyssal Plain.
- The description notes the evolution of sensor packages over time, adding parameters like fluorescence.
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 last update date is unknown; data freshness is unverified.
