Research vessel data collected by CEFAS (or DFR) using a lowered CTD rosette system while the vessel was stationary. The data broadly cover the European Shelf, with some measurements from the Iberian Abyssal Plain. Early years recorded a limited set of parameters like pressure, temperature, and conductivity, while later cruises added sensors for fluorometry, optical backscatter, and light.
Use Cases
- Calculate water salinity based on conductivity data using UNESCO 1978/1983 formulations mentioned in the description
- Analyze vertical ocean profiles for temperature and pressure (depth) collected from surface to near seabed
- Study biological activity by examining data from later-added sensors like fluorometers and PAR sensors
- Calibrate ocean models using in-situ measurements from research vessel stations
Strengths
- Data includes down-cast profiles described as clean for analysis
- Coverage spans the broad European Shelf and the Iberian Abyssal Plain
- Methodology includes water sample collection and calibration via bottles fired on the up-cast
Limitations
- Row count, file formats, and specific column definitions are unknown
- The exact sensor configuration and data format vary between cruises
- Last update date is unknown; freshness unverified
