Data are daily mean values derived from weekly sampling at 1200 h as well as monthly sampling every 4 h over the diel cycle (SI Appendix, Supplementary Information) and are shown as mean ± SD. The uncertainties associated with these values reflect daily and seasonal variability, as well as variability among replicate mesocosms in each treatment. The mean uncertainties among mesocosms on a given sampling day are provided in parentheses. Note that the variation among mesocosms is relatively small and most of the variation is explained by daily and seasonal fluctuation of these parameters. SI Appendix, Fig. S2 for additional environmental information.
