Abbreviations: TP = total phosphorus, TSi = total silicate, DIC = dissolved inorganic carbon, TA = total alkalinity, pCO2 = partial pressure of CO2, ΩCa = saturation state of calcite, Revelle factor = (ΔCO2(aq)/CO2(aq))/(ΔDIC/DIC).

All measured input parameters, beside TA, were used for CO2SYS calculations.
