Table 1.

Physico‐chemical parameters of seawater for the elevated and low p CO ₂ treatments. Values are means ±1 SD for pH (NBS scale), salinity, temperature, total alkalinity (TA), carbon dioxide partial pressure (p CO ₂), bicarbonate and carbonate ion concentration ([ ${HCO}_{3}^{-}$ ]) and ([ ${CO}_{3}^{2 -}$ ]), and calcite and aragonite saturation states (Ω_cal and Ω_ara)
