Supp. Figure 1. PCA of 16s rRNA reads extracted from metagenomes of chimney and biosyringe samples. Data source is the same table used for sample percent composition figure on the poster. Components are counts from all individiual NTUs per sample in this plot. Data was additive logratio transformed before principle component analysis was performed.
Supp. Figure 2. Additive logratios of 16S rRNA reads collapsed by functional group of NTUs as predicted by taxonomic assignment. This visualization demonstrates beta diversity of functional groups between samples regardless of the presence of other taxa in the sample due to compositional nature of sequence data.
Supp. Figure 3. Venn diagram of the overlap of presence of metagenome assembled genomes (MAGs) between hydrothermal vents along the Arctic Mid-Ocean Ridge (AMOR). Presence of a MAG was determined using an arbitrary genome coverage cutoff value of 0.25 after testing of several more arbitrarily-chosen cutoffs (10,1,0.25,0.1,0.001).
Supp. Figure 4. Seven MAGs belonging to the lineage Methylococcales represent the lineage with the most genomes out of the 28 genomes deemed present among all 5 AMOR vent sites. Additive log ratios of these MAG coverages are visualized to demonstrate beta diversity of these 7 MAGs.
