Fig. 1: Bacterial and archaeal community structure.

Compositional barplots showing relative abundances of a Bacteria and b Archaea ASVs in Saanich inlet seston samples. Dissolved oxygen profiles for each sampling period are reported in panel (a). Samples were obtained from Saanich inlet between April and October 2018. Sample labels on the vertical axes correspond to sampling month and water column depth. Vertical axis labels are color coded according to in situ dissolved oxygen concentrations.
