CEFAS research cruises collected this hydrographic data using a lowered CTD rosette system while vessels were stationary. The data broadly covers the European Shelf and the Iberian Abyssal Plain, with profiles taken from the surface to near the sea bed. The exact parameters measured evolved over time, starting with pressure, temperature, and conductivity, with later additions including fluorometers and light sensors.
Use Cases
- Calculate salinity profiles based on conductivity, temperature, and pressure data.
- Analyze vertical profiles of water properties like temperature and conductivity from surface to sea bed.
- Study spatial patterns of hydrographic conditions across the European Shelf.
- Calibrate satellite-derived oceanographic measurements using in-situ CTD data.
- Investigate temporal changes in ocean parameters as sensor configurations evolved over multiple cruises.
Strengths
- Data collection followed a standardized methodology using a lowered CTD rosette system on research vessels.
- The description specifies a broad geographic coverage of the European Shelf and the Iberian Abyssal Plain.
- The data includes high-resolution downcast profiles intended to be clean measurements.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- The exact sensor configuration and data format varied between cruises, requiring careful integration.
