RV Corystes 04/2000 Low Resolution CTD Data from the European Shelf

Corystes research cruise data collected using a lowered CTD rosette system while the vessel was stationary. The data broadly cover the European Shelf and the Iberian Abyssal Plain, with profiles from the surface to near the sea bed. The dataset was collected by CEFAS (or DFR) and aggregated by the Government Digital Service.

Use Cases

• Calculate salinity from conductivity data based on the UNESCO 1978/1983 formulations mentioned in the description
• Analyze vertical water column profiles based on pressure (depth), temperature, and conductivity data
• Study temporal changes in marine parameters based on data from early years with limited sensors versus later years with added sensors like fluorometers
• Calibrate sensor readings based on water samples taken from bottles fired at particular depths

Strengths

• Data collection follows a standardized methodology using a lowered CTD rosette system for clean down-cast profiles
• Coverage includes the broad European Shelf and the Iberian Abyssal Plain
• The description details the evolution of sensor configurations, adding parameters like fluorometers and optical sensors over time

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
