High-resolution oceanographic profiles collected from the surface to near the seabed using a lowered CTD rosette system. Data from the RV Corystes cruise in November 2002 broadly covers the European Shelf and the Iberian Abyssal Plain. The dataset was collected by CEFAS research cruises and includes core parameters like pressure, temperature, and conductivity, with salinity derivable using UNESCO formulations.
Use Cases
- Calculate seawater salinity based on conductivity, temperature, and pressure using the UNESCO 1978/1983 formulations mentioned in the description.
- Analyze vertical water column profiles from surface to seabed for physical oceanography studies.
- Calibrate sensor data using water samples collected from bottles fired at specific depths during the up cast.
- Study temporal changes in oceanographic parameters by comparing data from early years with later cruises that included additional sensors.
Strengths
- Data collection uses a lowered CTD rosette system designed for clean down-cast profiles.
- Core parameters allow for the calculation of salinity via established UNESCO formulations.
- Coverage includes the European Shelf and extends to the Iberian Abyssal Plain.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The exact sensor configuration varies between cruises, affecting data format consistency.
