  1. Numerically dominant diatom genera in blooms induced by large-scale iron fertilization experiments. Experiments summarized here are the Iron Enrichment Experiments I and II (IronExI and IronExII), Southern Ocean Iron Release Experiment (SOIREE), Iron Experiment (EisenEx), Subarctic Pacific Iron Experiment for Ecosystem Dynamics Study (SEEDS), Subarctic Ecosystem Response to Iron Enrichment Study (SERIES), Southern Ocean Iron Experiments – North and South (SOFeX north and south), European Iron Fertilization Experiment (EIFEX), and Subarctic Pacific Iron Experiment for Ecosystem Dynamics Study II (SEEDS II). The genus Pseudo-nitzschia is in bold to highlight the ubiquity of this genus in large-scale iron enrichment experiments. *Data from Boyd et al. [100]. §Data compiled from Marchetti et al. [101], Hoffmann et al. [102], Tsuda et al. [103] and [104], and Martin et al. [105], Landry et al. [106]. During IronExII, Pseudo-nitzschia was originally misidentified as Nitzschia (K. Coale, pers. comm.).
