Conductivity-temperature-depth (CTD) profiles collected from CEFAS research vessel cruises. The data broadly covers the European Shelf and the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The exact parameters collected vary by cruise, with early years focusing on pressure, temperature, and conductivity, while later years added sensors like fluorometers and transmissometers.
Use Cases
- Calculate salinity profiles based on conductivity data using UNESCO formulations.
- Analyze vertical water column structure based on pressure (depth), temperature, and conductivity profiles.
- Study temporal changes in oceanographic parameters across different research cruises.
- Calibrate sensor readings using water samples collected from bottle firings.
Strengths
- Data collection method is explicitly described as a lowered CTD rosette system for clean down-cast profiles.
- Covers a specific geographic area mentioned as the European Shelf and Iberian Abyssal Plain.
- Description details the evolution of sensor packages from basic CTD to include fluorometers and optical sensors.
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.
