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.\n\nComponent sensors:\n\nSensor | Make Model | Calibration\n\nNon-dispersive infra-red CO2 analyser | Licor | LI-7000 | Continuous (see below)\n\nEquilibrator temperature sensor | Hart-Fluke | 1521 | Jan 2017\n\nSurvey settings:\n\nThe 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.\n\nCalibration Information:\n\nThe 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.
