RV CORYSTES 11B/1997: High-Resolution Ocean CTD Profiles from the European Shelf

Research vessel CORYSTES collected this high-resolution Conductivity-Temperature-Depth (CTD) data during a 1997 cruise. The data likely contains profiles from the surface to near the sea bed, with parameters including pressure, temperature, and conductivity for calculating salinity. The dataset is provided by the Government Digital Service and originates from CEFAS research cruises broadly covering the European Shelf.

Use Cases

• Modeling oceanographic water column structure based on high-resolution CTD profiles.
• Calibrating satellite sea surface salinity measurements using in-situ conductivity data.
• Studying marine biogeochemistry by analyzing later-added sensor data for fluorescence or light (PAR).
• Analyzing temporal changes in shelf sea conditions by comparing this 1997 data with more recent cruises.

Strengths

• Data was collected using a lowered CTD rosette system, which typically provides high-resolution, clean down-cast profiles.
• The description indicates coverage of the European Shelf and the Iberian Abyssal Plain, providing a specific geographic scope.
• The methodology includes water sample collection for calibration, which can improve data accuracy.

Limitations

• Row count, file formats, and column-level documentation are unknown, which may limit suitability assessment.
• The exact sensor configuration and available parameters vary between cruises, requiring inspection of the specific output files.
• Last update date is unknown; freshness unverified.
