(A) seawater parameters during the experimental incubation, daily measurements (T, S, pH) and averages of four determinations (cell densities in aquaria and header tanks); (B) carbonate system speciation calculated from pHNBS and total dissolved inorganic carbon (C T) measurements, mean values of two determinations in all 32 experimental tanks; (C) mussel growth trial results. Means and standard deviations (in brackets). F1 = factor 1, food level; F2 = factor 2, pCO2, A T = total alkalinity. A seawater pCO2 of 100 Pascal (Pa) corresponds to 987 µatm.
