RV CORYSTES 11B/1995: Low-Resolution CTD Profiles from the European Shelf

CEFAS research vessel RV CORYSTES collected this low-resolution Conductivity-Temperature-Depth (CTD) data during the 11B/1995 cruise. The data broadly cover the European Shelf and the Iberian Abyssal Plain, with profiles taken from the surface to near the seabed. Data collection used a lowered CTD rosette system, with water samples taken for calibration.

Use Cases

• Calculate salinity from conductivity data based on the UNESCO 1978/1983 formulations mentioned in the description.
• Analyze vertical oceanographic profiles based on pressure (depth), temperature, and conductivity data.
• Study temporal changes in marine parameters by comparing this early-year dataset with later cruises that added sensors like fluorometers.
• Calibrate or validate ocean models using in-situ CTD profile data from a specific research vessel and cruise.

Strengths

• Data originates from a specific, named research vessel and cruise (RV CORYSTES 11B/1995), providing clear provenance.
• Description details the standardized data collection method using a lowered CTD rosette system on station.
• The geographic coverage is specified as the European Shelf and the Iberian Abyssal Plain.

Limitations

• Row count, file formats, and column-level documentation are unknown, which limits suitability assessment.
• The last update date is unknown, making data freshness unverified.
• The description notes that in early years only a limited set of parameters were collected, suggesting fewer variables than later cruises.
