- Salinity, temperature and pH (NBS scale) were determined using a YSI 63 probe. Total alkalinity was measured in an automatic titrator (Metrohm 888 Titrando) and pCO2 was calculated using co2sys software [33]. Data are presented as mean ± SD (n = 66 per treatment; 3 tanks × 22 days). Abbreviations: a ambient, e elevated, T temperature
