The absolute average difference from the mean of these replicates are less than 0.85 μmol/kg.

The total alkalinity analyses performed during I6S, were performed using a two-stage, potentiometric, opencell titration and coulometrically analyzed hydrochloric acid.; Uncertainty: Precision ~ 1.5 μmol/kg, Accuracy ~ 2.0 μmol/kg; Method reference: Dickson, Andrew G., Chris Sabine and James R. Christian, editors, Guide to Best Practices for Ocean CO2 Measurements, Pices Special Publication 3, IOCCP Report No. 8, October 2007, SOP 3b, Determination of total alkalinity in sea water using an open-cell titration. Parameter or Variable: pH; Abbreviation: PH_TOT; pH scale: Total scale; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Measured or calculated: Measured; Temperature of pH measurement: 20; Detailed sampling and analyzing information: pH values are determined at a reference temperature of 20 C using the constants of Liu et al. (2011). These values are further adjusted to counter errors created by using constants determined for purified m-cresol dye for measurements made with unpurified (Acros Organics) dye. The applied adjustment is a pH dependent offset estimated by fitting a 2nd order polynomial to the data in figure 2a in the article by Liu et al. (2011). The likely uncertainties on these measurements are explored in detail in Carter et al. (conditionally accepted, 2012).; Uncertainty: Accuracy of spectrophotometric pH measurements is difficult to constrain with no agreed upon calibration procedure. For this cruise two approaches were made. First, since the same bottles that were sampled for alkalinity and total carbon were sampled for pH, an independent estimate of pH can be obtained from equilibrium equations. Second, pH analyses of Certified Reference Materials (currently only certified for DIC and alkalinity) were performed. A review of the accuracy of the pH measurements is underway, and large changes (~0.01) in the final reported values are likely. Confidence in the precision of the measurements remains high, and likely changes would be a simple offset or an offset that is a simple function of reported pH.
