RV Corystes 11/1989 Low-Resolution CTD Data from the European Shelf

Data from a 1989 research cruise by CEFAS (or DFR) using a lowered CTD rosette system. The dataset likely contains profiles of pressure, temperature, and conductivity, from which salinity can be derived. It broadly covers the European Shelf with some data from the Iberian Abyssal Plain.

Use Cases

• Calculate salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical water column structure from surface-to-sea-bed profiles.
• Calibrate oceanographic models using in-situ measurements from the European Shelf.
• Study temporal changes in marine environments by comparing with newer datasets.

Strengths

• Data collected using a standardized lowered CTD rosette system, a common oceanographic method.
• Profiles are designed to be clean on the down cast, suggesting controlled data collection.
• Coverage includes the broad European Shelf and the Iberian Abyssal Plain.

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.
• Last update date is unknown; freshness unverified.
