Bacterial community composition from Louisiana marshes, May 2010-September 2011, August 2013

This dataset provides the sediment bacterial community compositions of eleven coastal Louisiana marshes after the Gulf of Mexico oil spill in 2010. Samples were collected from May 2010 through August 2013, focusing on sediments approximately 1 m offshore from the edge of the marsh. Bacterial communities were assessed from sediments at 0-1 cm and 1-2 cm depth intervals. Taxonomic classifications are provided at the phylum, class and order levels. The results are based on amplicon pyrosequence libraries of single-direction reads generated using multiplexed, bar-coded primers targeting the V1-V3 region of the bacterial of 16S rRNA gene. This dataset reports rapid taxonomic summaries from R1.x139.143:0010. Access to raw 16S rRNA amplicons generated for this study were submitted to the NCBI Sequence Read Archive under BioProject ID PRJNA232457 (http://www.ncbi.nlm.nih.gov/).
