Prokaryotic community and diversity in coastal surface waters along the Western Antarctic Peninsula
Identifying microorganisms and defining the community compositions are important for better understanding of the marine ecosystem and biochemical cycles. This study describes microbial community compositions of coastal surface waters of the Western Antarctic Peninsula (WAP). The V3–V4 regions of 16S...
