16S rRNA gene amplicons analysis. (a) Bray-Curtis similarity clustering of the samples based on (b) archaeal 16S rRNA gene sequences (OTU at 97% similarity). (c) Bray-Curtis similarity clustering of the sample based on (d) bacterial 16S rRNA gene sequences (OTU at 97% similarity). Samples not associated with active seeps (PC11 and PC12) are labeled with brown dots, Site1 oil seep samples (PC5 and PC6) with green dots and Site2 oil seep samples (PC9 and PC10) with yellow dots.
