Mean carbonate chemistry values associated with experimental cultures (<i>t2</i>).

aAverage values at the beginning of the experiment before the inoculation of cells. bFigures in parentheses represent blank seawater medium bubbled with the appropriate pCO2 mixture. cThere was only one sample available for the initial pre-inoculation blank of the ambient/current day CO2 condition. For this instance alone, values in parentheses are from the second 395 p.p.m.v. CO2 treatment. dAverage values at the end of the experiment (t2).
