RV CORYSTES 5B/1995: Low-Resolution CTD Data from the European Shelf

CEFAS research cruises collected this oceanographic data using a lowered CTD rosette system while vessels were stationary. The data broadly covers the European Shelf with some measurements from the Iberian Abyssal Plain. Parameters likely include pressure (depth), temperature, and conductivity, with salinity calculated using UNESCO formulations; later cruises added sensors for fluorometry, optical backscatter, and light.

Use Cases

• Calculate water salinity profiles based on conductivity, temperature, and pressure data.
• Analyze vertical ocean structure for temperature and density based on CTD cast profiles.
• Study phytoplankton distribution patterns using later cruise data that includes fluorometer readings.
• Calibrate satellite-derived ocean color data using in-situ optical measurements like transmissometer data.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system.
• Coverage includes the broad European Shelf and extends to the Iberian Abyssal Plain.
• The description notes a progression in sensor capabilities, adding parameters like fluorometry in subsequent years.

Limitations

• Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
• The exact data format and parameters vary between cruises, requiring manual inspection after download.
• Last update date is unknown; freshness unverified.
