a Chlorophyll a-based accumulation rate (d−1) of all (total), the small (0.2–2 μm) and the large (>2 μm) cells (n = 3), b net growth rate of each picoeukaryote group (subgroups P1–P3) determined via flow cytometry (n = 6) and c net growth rate of Chaetoceros sp., Fragilariopsis sp., Pseudo-nitzschia sp. and Phaeocystis antarctica determined via light microscopy (n = 3). All parameters were estimated from the community sampled at station West (BIO1) after exposure to different Fe and Mn availabilities (Supplementary Fig. 2). Values represent the mean ± SD. Different letters indicate significant differences between treatments (p < 0.05).
