C. Time series results of the CSI, Metrohm data and reference pH data are shown in
middle panel and the time series of the calculated difference between CSI and reference pH are
shown in the bottom panel. The average difference between instrument and reference pH for the
brackish water component was 0.226 ± 0.059, with a total range of 0.121 to 0.314 (N=76).
During the freshwater trials, salinity was maintained to within 0.11 units (range = 0.19 to
0.30) with an average of 0.26 and temperature to within 0.9
