Abstract
Hain et al. (2015, https//doi.org/10.1002/2014GB004986, hereafter H15) calculated effects of changing [Ca2+] and [Mg2+] on the equilibrium constants of the CO2-CaCO3 system in seawater based on a Pitzer ionic interaction model. We show here that critical results presented in H15 are fundamentally wrong. We therefore do not recommend using H15's stoichiometric equilibrium constants to correct for past changes in major-ion seawater composition.
