  1. pH was monitored by the pH/CO2 system continuously during the experiment. Salinity, temperature and total alkalinity (TA) were determined at each sampling time (n = 5). Dissolved inorganic carbon (DIC), partial pressure of CO2 (pCO2), saturation degrees for calcite ( Ωcal) and aragonite (Ωara) were calculated based on the above parameters
