Summary of carbonate chemistry of seawater used in the experiment
| Parameter (unit) | Ambient CO2 LC | Elevated CO2 HC |
|---|---|---|
| AT (μmol kg−1) | 2197.44 ± 11.99 | 2207.55 ± 15.97 |
| DIC (μmol kg−1) | 2031.41 ± 11.23 | 2170.76 ± 15.74 |
| H2CO3 (μmol kg−1) | 18.49 ± 0.11 | 48.02 ± 0.51 |
 (μmol kg−1) |
1890.43 ± 10.37 | 2066.36 ± 14.97 |
 (μmol kg−1) |
122.48 ± 0.88 | 56.38 ± 0.66 |
| pCO2 (μatm) | 471.38 ± 2.87 | 1223.91 ± 13.02 |
| pHT | 7.965 ± 0.002 | 7.590 ± 0.004 |
Carbonate parameters were calculated from total alkalinity (AT) and pHT measurements corresponding to each pCO2 treatment at 13 ± 1°C. Seawater was filtered and nutrient-enriched (ENSW formula), salinity 34 psu. Data are means ± standard deviations (n = 12).
