Figure 2: Taxonomic assignments for each sampled water mass.

Relative abundances of OTUs in each sampled water mass and size fraction. OTUs that formed by clustering against SILVA 16S rRNA gene seed sequences were aggregated to the phyla associated with those sequences, except for members of the Proteobacteria, which were aggregated to class when known. OTUs generated by de novo clustering were aggregated as ‘unknown’. For ease of comprehension, phyla or classes with a mean relative abundance across all samples and fractions <1% were aggregated into a single group labelled ‘other’. Relative abundance was scaled to account for discarded reads. Surface water masses are in the top row and deeper water masses are in the bottom row.
