## International inter-comparison of fCO2 systems during the R/V Meteor Cruise In June 1996

**Notes:**
Details of our underway pCO2 system were reported in this book published by the DOE, USA. We participated the international intercomparison exercise of underway fCO2 systems which was conducted in the North Atlanic Ocean aboard the R/V Meteor in June 1996.
