RV Corystes 3A/1992: High-Resolution Ocean CTD Profiles from the European Shelf

Conductivity-Temperature-Depth (CTD) data collected from CEFAS research vessel cruises. The data broadly cover the European Shelf, with some measurements from the Iberian Abyssal Plain, using a lowered CTD rosette system while the vessel was stationary. Water samples were taken for calibration, and the parameters collected likely include pressure, temperature, and conductivity, with later cruises adding sensors for fluorescence, optical backscatter, and light.

Use Cases

• Calculating ocean salinity profiles based on conductivity and temperature data mentioned in the description
• Analyzing vertical water column structure based on high-resolution CTD profiles from surface to sea bed
• Calibrating satellite or model-derived ocean data using in-situ bottle sample measurements described
• Studying spatial patterns of marine properties across the European Shelf geography covered

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system
• Description indicates coverage of a specific geographic region: the European Shelf and Iberian Abyssal Plain
• Later cruises included additional sensors for parameters like fluorescence and light, suggesting evolving data richness

Limitations

• Row count and file size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics and sensor configuration must be inferred after download
• Last update date is unknown; freshness unverified
