RV Corystes 1991 Low-Resolution CTD Data from the European Shelf

Data collected in November 1991 from CEFAS research vessel RV Corystes using a lowered CTD rosette system. The dataset likely contains profiles of pressure, temperature, and conductivity from the European Shelf and Iberian Abyssal Plain, with salinity derivable from conductivity. The data was collected by the Government Digital Service.

Use Cases

• Analyze vertical water column profiles based on pressure, temperature, and conductivity data.
• Calculate historical salinity levels based on conductivity using UNESCO formulations.
• Study calibration methods for CTD sensors based on the description of bottle sampling.
• Examine early marine data collection practices based on the limited parameter set described.

Strengths

• Data collected using a standardized lowered CTD rosette system, which suggests methodological consistency.
• Covers a defined geographic area including the European Shelf and Iberian Abyssal Plain.
• Collected by a governmental research organization (CEFAS/DFR), suggesting an authoritative source.

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.
