For Using Data

Masao Ishii (Meteorological Research Institute)
See Terms and Conditions about constrain of use.
See Terms and Conditions about data citation.
Instrument:
TCO2 measurement system ( - MR09-03 Leg3)
Instrument : Underway TCO2 measuring system;Nippon ANS Ltd.
Method : Coulometric
Precision : -
Reference Material/Calibration : Certified Reference Material for TCO2 analysis provided by Dr A. G. Dickson

- Measured by Meteorological Research Institute using coulometric technique (Ishii, et al., 1998).
- Total alkalinity (TA) has been calculated from TCO2, SST, salinity and pCO2 that have been concurrently measured using carbonic acid dissociation constants given by Roy et al., 1993.
