16S rRNA gene amplification from Mercer Subglacial Lake filtered water from clean access sampling: Sample port 9, 300 m below ice surface
16S rRNA gene was PCR amplified with the primers described in Caporaso et. al. 2012 ISME Journal (doi:10.1038/ismej.2012.8) and sequenced as 300 pb paired end reads on an Illumina MiSeq v6
