DIC and A_T were inputted into the Excel macro CO₂SYS and used to calculate pH at total scale (pH_T), partial pressure of carbon dioxide (pCO₂), bicarbonate (HCO₃⁻), carbonate (CO₃²⁻), aqueous carbon dioxide (CO_2(aq)), the saturation state of calcite (Ω_CA), and the saturation state of aragonite (Ω_AR).
