During the second bloom, PP T amounted to highest values of 11.3 ± 5.0 μmol C L -1 d -1 at t53 for high p CO 2 , and 6.0 ± 1.9 μmol C L -1 d -1 at day t57 for low p CO 2 At the peak of the second bloom, PP T appeared to be higher at high p CO 2 , though this difference was marginally significant and dependent on time ( Table 2 ; rmANOVA, Time x CO 2 treatment, P = 0.098).
