RV CORYSTES 9A/2000 Low Resolution Conductivity-Temperature-Depth (CTD) Data

CEFAS research cruises collected this oceanographic data using a lowered CTD rosette system while vessels were stationary. The data broadly covers the European Shelf and includes profiles from the surface to near the sea bed, with parameters such as pressure, temperature, and conductivity. In subsequent years, sensors for fluorometers, optical back scatter, transmissometers, and light were added, though the exact configuration varies by cruise.

Use Cases

• Calculate ocean salinity profiles based on conductivity data using UNESCO formulations.
• Model water column stratification and mixing based on temperature and depth profiles.
• Analyze phytoplankton biomass distribution based on fluorometer data mentioned in the description.
• Study sediment transport or water clarity based on optical back scatter or transmissometer data.
• Investigate photosynthetic activity in marine environments based on PAR (photo synthetically available radiation) light data.

Strengths

• Data collection follows a standardized oceanographic method using a lowered CTD rosette system.
• Coverage includes the European Shelf and some data from the Iberian Abyssal Plain.
• The description specifies core parameters (Pressure, Temperature, Conductivity) and later additions like fluorometers.

Limitations

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