Evaluation of the temperature dependence of dissociation constants for the marine carbon system using pH and certified reference materials

Ryan J. Woosley

Summary: The study evaluates the marine carbon cycle using internal consistency calculations and spectrophotometric pH measurements, revealing that the choice of formulation for certain dissociation constants may add uncertainties. The total boron concentration significantly impacts the calculated pH, with the recommendation to use the values of Lee et al. (2010) for better internal consistency.

Spectrophotometric determination of the bicarbonate dissociation constant in seawater

Katelyn M. Schockman et al.

Summary: The study emphasizes the significance of CO2 system in seawater and oceans and the importance of dissociation constants related to pH. It improves the accuracy of calculations by experimentally determining K1K2 and obtaining a new pK(2) parameterization, which shows better consistency and reduced uncertainty compared to previous characterizations. The new K-2 parameterization provides the most precise characterization of bicarbonate dissociation constant for open ocean conditions.
