RV Corystes 09/1996 High Resolution Conductivity-Temperature-Depth (CTD) Data

High-resolution oceanographic profiles collected from the CEFAS research vessel RV Corystes in September 1996. Data was gathered using a lowered CTD rosette system while the vessel was stationary, capturing profiles from the surface to near the seabed. The dataset broadly covers the European Shelf, with some data from the Iberian Abyssal Plain.

Use Cases

• Calculate ocean salinity based on conductivity data using UNESCO 1978/1983 formulations.
• Analyze vertical water column structure based on high-resolution pressure (depth), temperature, and conductivity profiles.
• Calibrate sensor readings using water samples collected from bottles fired at specific depths on the up cast.

Strengths

• Data collection used a lowered CTD rosette system, which the description suggests provides clean down-cast profiles.
• The description indicates the dataset includes core oceanographic parameters: Pressure (Depth), Temperature, and Conductivity.

Limitations

• Description metadata is limited; actual data quality, file formats, and column definitions require manual inspection after download.
• Row count, file size, and specific column names are unknown, which may limit suitability assessment.
• The exact sensor configuration varies between cruises, which may affect data consistency.
