Intercomparison of CO 2 measurements
Abstract
Seawater samples, of four different salinities, were analysed for total alkalinity, total CO 2, pH and pCO 2 by up to 12 laboratories. The results showthat although most laboratories are capable of high precision in these determinations, there is an unacceptably high disagreement between their analyses of the same samples. For global programmes involving studies of the CO 2 system in seawater, it is strongly recommended that standard reference materials be made widely available.
