16S rRNA gene amplification from Mercer Subglacial Lake bed sediments: Sample freefall core 2, collection depth 87-92 cm, composite depth 109.5-114.5 cm
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 v3
