In one embodiment, determining carbon system parameters of water includes measuring the pH of a first subsample of the water using a spectrophotometer, adding nitric acid as a titrant to a second subsample of the water to obtain a titrated subsample, measuring a concentration of added nitric acid in the titrated subsample using a spectrophotometer, measuring the pH of the titrated subsample using a spectrophotometer, and calculating one or more unknown carbon system parameters using the pH of the first subsample, the pH of the titrated subsample, and the concentration of added nitric acid of the titrated subsample.
