Table 1. Seawater conditions for each experimental treatment.
Calcite and aragonite saturation states (ΩCa and ΩAr, respectively) and pCO2 are calculated values from the measured pHT, and the alkalinity (AT ) measured in February 2011 (AT = 2,228.3 ± 1.6; N = 11) at a salinity of 34.5. Data presented for pHT are averages ± SE.
| Temperature (°C) | pHT* | ΩCa | ΩAr | pCO2 |
|---|---|---|---|---|
| 12.60 ± 0.01 | 8.03 ± 0.00 | 3.27 | 2.09 | 395 |
| 7.66 ± 0.00 | 1.52 | 0.97 | 1,023 | |
| 14.89 ± 0.00 | 8.00 ± 0.00 | 3.34 | 2.14 | 432 |
| 7.66 ± 0.00 | 1.66 | 1.07 | 1,041 |
