Total dissolved iron (dFe) concentrations and carbonate chemistry determined at the end of the experiment in the culture medium (filtered seawater without cells) and the P . subcurvata incubations of the four treatments ( +Fe 190 , Control 190 , +Fe 290 and Control 290 ).

The pCO 2 was calculated from measured dissolved inorganic carbon (DIC) and total alkalinity (TA). For the culture medium, dFe, TA, DIC and pCO 2 values represent the range of duplicate abiotic controls. TA, DIC and pCO 2 values of the P . subcurvata incubations represent the means ± SD (n = 3). Differences between the individual treatments of the P . subcurvata incubations were determined with post hoc tests, where significant statistical (p < 0.05) differences are denoted by different letters.
