Rates and Hg stable isotope signatures of photomicrobial transformations of Hg(II) and MeHg in marine phytoplankton exposed to visible light and varying levels of UV radiation were examined in experiments with (1) sterile-filtered spent growth media containing extracellular exudates from cultures of Isochrysis galbana, a eukaryotic marine microalga of the globally important Prymnesiophyceae class; (2) actively growing monospecific cultures of I. galbana; and (3) cysteine or ocean water washed (nongrowing) I. galbana cells.

These data were published in Supplementary Table 4 of Kritee, et al. (2017).
