Fig. 1. — Temporal changes in pCO₂ (A), pH (B), chlorophyll a (C), and the concentrations (pM) of methyl iodide CH₃I (D), ethyl iodide C₂H₅I (E), diiodomethane CH₂I₂ (F), chloroiodomethane CH₂ClI (G) over the course of the experiment. Data for M3 and M4 only is shown from May 16 onward as the remaining four mesocosms underwent a second aeration on May 15. Chl a concentrations were significantly lower under high CO₂ for the bloom period May 10 to 17 (T = 2.45, P = 0.021). Significant differences were found for CH₃I for the bloom period (T = 2.75, P = 0.012). The postbloom period May 18 to 23 saw reductions in all iodocarbons under high CO₂: CH₃I (−67%), C₂H₅I (−73%), CH₂I₂ (−93%), and CH₂ClI (−59%). pH data calculated using TA and pCO_2. See Tables S1–S5 for details of statistical analyses.
