Table 1 Carbonate chemistry of seawater at sampling sites 1 (control), 2 (intermediate pCO2) and 3 (high pCO2). Parameters were calculated from pHNBS, total alkalinity (TA), ambient seawater temperature and salinity (38‰) using the program CO2SYS54. All data shown are the mean (±SD). Dissolved inorganic carbon (DIC)

2. Intermediate pCO2 | 7.99 (0.07) | 2486 (9) | 683 (62) | 2287 (46) | 2113 (65) | 152 (23) | 22 (4) |
3. High pCO2 | 7.44 (0.26) | 2501 (20) | 3232 (836) | 2585 (123) | 2430 (93) | 50 (25) | 105 (53) |
