Seawater measurements from experimental aquaria: measured values of temperature (T), salinity (S), pH (NBS scale), total alkalinity (TA); and calculated values (using CO2SYS) of dissolved inorganic carbon (DIC), seawater pCO2, saturation states for calcite (Ωcalcite) and aragonite (Ωaragonite), bicarbonate (HCO3−) and carbonate concentration (CO32−).
