High-resolution Conductivity-Temperature-Depth (CTD) data collected from CEFAS research surveys on the European Shelf and Iberian Abyssal Plain. Data was gathered using a lowered CTD rosette system while vessels were stationary, with water samples taken for calibration. The parameters collected likely include pressure, temperature, and conductivity, with salinity calculable from conductivity.
Use Cases
- Calculate salinity profiles based on conductivity data using UNESCO formulations mentioned in the description.
- Analyze vertical profiles of temperature and pressure to study water column structure.
- Calibrate sensor readings using water sample data collected on the up cast.
- Study temporal changes in oceanographic parameters across different research cruises.
Strengths
- Data is described as high-resolution, suggesting detailed vertical profiles.
- Covers a broad geographic area including the European Shelf and Iberian Abyssal Plain.
- Methodology for data collection (lowered CTD rosette system) and calibration (water samples) is specified.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
