Instrument:
TCO2 measurement system (MR09-04 - )
Instrument : Underway TCO2 measuring system´╝ŤNippon ANS Ltd.
Method : Coulometric
Precision : -
Reference Material/Calibration : Certified Reference Material for TCO2 analysis provided by Dr A. G. Dickson (batch 156)

  1. TCO2 samples are analyzed using coulometric technique (Ishii, et al., 1998). Batches of Certified Reference Material for TCO2 analysis provided by Dr A. G. Dickson have been used for quality control. Significant offset, if any, has been corrected.
    Also, please refer to cruise report for details of the analytical method.
