Data collected from CEFAS research cruises in April 1991. The dataset contains low-resolution Conductivity-Temperature-Depth (CTD) profiles from the European Shelf and the Iberian Abyssal Plain, gathered using a lowered CTD rosette system while the vessel was stationary. It was collected by the Government Digital Service.
Use Cases
- Calculate salinity from conductivity data based on the UNESCO 1978/1983 formulations mentioned in the description.
- Analyze vertical water column profiles (surface to sea bed) based on the down cast data described as a clean profile.
- Study the historical evolution of oceanographic sensors by comparing the limited early parameters (Pressure, Temperature, Conductivity) with later additions like fluorometers.
- Calibrate modern sensor readings using the historical bottle sample data collected on the up cast, as described.
Strengths
- Data collection methodology is explicitly described, involving a lowered CTD rosette system and calibration water bottles.
- Geographic coverage is specified, including the European Shelf and the Iberian Abyssal Plain.
- The core parameters (Pressure, Temperature, Conductivity) for calculating fundamental oceanographic properties are present.
Limitations
- Row count, file formats, and column-level documentation are unknown, which limits suitability assessment.
- The exact sensor configuration and data format vary between cruises, requiring manual inspection after download.
- Last update date is unknown; freshness unverified.
