Extended Data Fig. 1: Abundance of Campylobacterota and hydrothermal plume Sulfurimonas sp. cells at Arctic sites.
a, Proportion of Campylobacterota and hydrothermal plume Sulfurimonas sp. to DAPI-stained cell counts in different water types at Aurora vent and reference sites (water depth and number of samples are reported in parenthesis); b − g, fluorescence micrographs of microbes in the Aurora plume (station PS86-55) stained with DAPI (blue; b and e) and simultaneously (double CARD-FISH) with specific probes for Campylobacterota (green; c and f) and for Arctic Sulfurimonas OTU1 (red; d) and OTU2 (red; g). Panels b–g represents observations made from independent samples (n = 3). Scale bars 10 μm (b–g).
