RV Corystes 1B/1994: High-Resolution Ocean CTD Profiles from the European Shelf

CTD data collected from CEFAS research cruises on the European Shelf and Iberian Abyssal Plain. Data were gathered using a lowered CTD rosette system while the vessel was stationary, with water samples taken for calibration on the up cast. The dataset likely contains profiles of pressure, temperature, and conductivity, with salinity calculated using UNESCO formulations.

Use Cases

• Modeling water column stratification based on temperature and salinity profiles.
• Calibrating satellite-derived sea surface salinity using in-situ conductivity data.
• Studying phytoplankton dynamics using fluorometer data mentioned in the description.
• Analyzing sediment transport or water clarity using optical backscatter or transmissometer data.

Strengths

• Data collection follows a standardized method using a lowered CTD rosette system.
• Profiles are designed to be clean from the surface to near the sea bed on the down cast.
• Water samples for calibration were collected, suggesting efforts towards data accuracy.

Limitations

• Row count, file formats, and column-level documentation are unknown.
• The exact sensor configuration varies between cruises, which may affect data consistency.
• Last update date is unknown; freshness unverified.
