RV CIRLANA 1995 Low-Resolution CTD Data from the European Shelf

Low-resolution Conductivity-Temperature-Depth (CTD) data collected from CEFAS research cruises in January 1995. The data broadly cover the European Shelf with some measurements from the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The dataset likely contains core parameters like pressure, temperature, and conductivity, from which salinity can be derived.

Use Cases

• Analyzing historical water column structure based on CTD profiles mentioned in the description
• Calculating salinity from conductivity data using the UNESCO 1978/1983 formulations referenced in the description
• Studying sensor evolution in marine research, as the description notes early years had limited parameters with more added later
• Calibrating modern oceanographic models with historical baseline data from the European Shelf

Strengths

• Data collected using a standardized lowered CTD rosette system, which the description notes provides clean down-cast profiles
• Covers a specific geographic area (European Shelf and Iberian Abyssal Plain) as stated in the description
• Core parameters (pressure, temperature, conductivity) allow for derivation of fundamental oceanographic properties like salinity

Limitations

• Row count is 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
