CCS - MV Bluefin 2017 V01 fCO2

A General Oceanics model 8050 fCO2 analyser was installed in the carbon team’s container and measured seawater from the ship’s auxiliary seawater pump for the duration of the voyage. Component sensors: Sensor | Make Model | Calibration Non-dispersive infra-red CO2 analyser | Licor | LI-7000 | Continuous (see below) Equilibrator temperature sensor | Hart-Fluke | 1521 | Jan 2017 Survey settings: The instrument was configured in continuous flow mode with a measurement interval of 30 seconds. Seawater fCO2 measurements are interrupted for about 22 minutes every 4 hours for analysis of calibration gases and atmospheric air. Calibration Information: The system ran a set of 4 calibration gases every 4 hours. Calibration gas concentrations are 0.00 ppm, 261.41 ppm, 377.78 ppm and 450.79 ppm. Calibrations are applied in post-processing.
