The absolute average difference from the mean of these replicates is 0.85 μmol/kg. No significant systematic differences were noted.; Standardization description: The coulometers were each calibrated by injecting aliquots of pure CO2 (99.995%) by means of an 8-port valve outfitted with two sample loops (Wilke et al., 1993). The instruments were calibrated at the beginning of each station with two sets of the gas loop injections.; CRM batch number: batch 89 Parameter or Variable: Total alkalinity; Abbreviation: TA; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Measured or calculated: Measured; Type of titration: potentiometric titration; Cell type (open or closed): Open Cell; Curve fitting method: Analysis of seawater for total alkalinity, AT, was performed using an open cell, potentiometric titration method published by Dickson et al. [2003] and subsequently adopted as one of standard analytical methods for ocean carbon measurements [Dickson et al., 2007].; Uncertainty: Analytical accuracy was assessed by periodic analysis of CRMs (Batch 89: supplied by Dr. A. Dickson of Scripps Institution of Oceanography; http://andrew.ucsd.edu/co2qc/index.html) throughout the cruise. References were analyzed approximately every 24 samples. Standard deviation over the course of the cruise is approximately 2.5 μmol kg-1. In addition, duplicate samples were taken at each station, totaling about 10% of samples analyzed, with an average standard deviation of 2.9 μmol kg-1.; Method reference: A. G. Dickson, J. D.
