 event
 Details of measurement and calibration methods are reported by Matsueda et al. (2000) (See reference section). All of the CO measurements are re-calculated based on the MRI scale, as reported by Tsuboi et al. (2017) (See reference section). The precision of the CO analysis was about 0.003 ppm at laboratory, but the shipboad measurments showed a larger precision of about 0.03 ppm due to the vibration of research vessel.
