16S amplicons of iron mats: upstream of hydrocarbon seep, seep
Samples of iron-oxide mats were collected from Town Creek, Greenville, NC, a freshwater urban stream. The mats were either upstream (U) or downstream (Da,Db) of a hydrocarbon seep from two leaking underground storage tanks. Metagenomic DNA was extracted using the Qiagen PowerSoil DNeasy Kit and sequenced using universal V4 V5 primers.
