RV Corystes 1989 Low-Resolution CTD Data from European Shelf

Low-resolution Conductivity-Temperature-Depth (CTD) data collected from the CEFAS research vessel RV Corystes in August 1989. The data broadly covers the European Shelf and the Iberian Abyssal Plain, collected using a lowered CTD rosette system while the vessel was stationary. The dataset is provided by the Government Digital Service via the eu_open_data platform.

Use Cases

• Calculating salinity from conductivity data based on the UNESCO 1978/1983 formulations mentioned in the description
• Analyzing vertical water column profiles from surface to near seabed based on the described collection method
• Calibrating modern sensor data with historical baseline measurements of pressure, temperature, and conductivity
• Studying temporal changes in marine environments using data from early years with a limited parameter set

Strengths

• Data collection method is explicitly described as using a lowered CTD rosette system for clean down-cast profiles
• Geographic coverage is specified as the European Shelf and Iberian Abyssal Plain
• The data source is identified as a CEFAS research cruise from a known vessel and month

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

Provenance

Source

Government Digital Service via eu_open_data platform, originally from CEFAS (Centre for Environment, Fisheries and Aquaculture Science) research cruise.

Collection Method

Collected using a lowered CTD rosette system while the vessel RV Corystes was stationary, with water samples taken for calibration.

Time Range

August 1989

Freshness

Data is from a single cruise in August 1989; temporal coverage is limited.

Geography
