Water mass and microbial community partitioning across the Beaufort Sea water column. (a) Hierarchical clustering on temperature, salinity and dissolved O2 distances (centered-scaled; z-score scale denoted by color gradient) on 24 seawater samples collected for microbial sampling. The water column partitioned into the PML, PSW and PWW water masses. The station number and depth classifications are indicated by the given symbols. (b) Hierarchical clustering on weighted UniFrac distances (dW5000) of OTUs. Communities were classified into four distinct clusters: Surface (brown; support, 65% of 1000 jackknife replicates), SCM (cyan, 58%), wSCM (pink, 91%) and Deep (lavender, 93%). (c) NMDS ordination on dW5000 distances (2D stress=0.0971). For each community cluster, ellipses represent 95% confidence intervals. Arrows represent best explanatory environmental and biological variables fitted onto the ordination space (environmental factors as in Supplementary Table S3).
