RV Corystes 13/2004: High-Resolution CTD Oceanographic Profiles

Data collected from the CEFAS research vessel RV Corystes during cruise 13/2004. The dataset contains high-resolution Conductivity-Temperature-Depth (CTD) profiles from the European Shelf and Iberian Abyssal Plain, collected using a lowered rosette system with water samples for calibration. The exact parameters vary by cruise but likely include pressure, temperature, conductivity, and may include fluorometer or light sensor data from later years.

Use Cases

• Calculate water salinity and density profiles based on the described conductivity, temperature, and pressure measurements.
• Analyze vertical ocean structure and water mass properties from the surface-to-sea-bed profile data.
• Calibrate satellite-derived oceanographic data using the in-situ bottle sample calibration mentioned.
• Study temporal changes in marine environments by comparing this cruise data with other time-series collections.

Strengths

• Data is described as high-resolution, collected from the surface to near the sea bed.
• Includes water bottle samples taken for calibration, which can improve data accuracy.
• Covers a specific geographic area (European Shelf and Iberian Abyssal Plain) from a named research cruise.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The exact sensor configuration and available parameters vary between cruises, as noted in the description.
