MIMOSA sediment chamber 16S rRNA gene sequence data, Gulf of Mexico, October 1, 2013 to March 30, 2014

This dataset contains the bacterial and archaeal 16S rRNA sequence information from the Methane Microbial Observatory for Seafloor Analysis (MIMOSA) deployment at GC600 from October 2013 (PE14-09) to March 2014 (PE14-14). The purpose of the deployment was to examine the in situ degradation of oil. The deployment contained flow-through chambers of sediment, one amended with oil and one unamended. Samples were collected from the beginning and end of the experiment. The dataset contains three types of files for both bacterial and archaeal sequences, generated from QIIME-pipeline analysis of Illumina MiSeq sequencing data: (1) FASTA formatted files of sequences of representative operational taxonomic units (OTUs), (2) a list of the abundance of each OTU in each sample, and (3) a list mapping individual sequences to each OTU.
