Carbonate chemistry for each CO2 concentrations (400, 550 and 750 μatm) after 11 and 20 months of high CO2. Total alkalinity (TA), salinity (Sal.), temperature (T) and pH were measured while dissolved inorganic carbon (DIC) and aragonite saturation state (Ωarag) were calculated using CO2SYS software. Values expressed as means ± standard error (n = 11)
