Microbial community composition of sediments associated with co-occurring Avicennia sp. and Spartina sp. in Chandeleur Island salt marsh seven and eight years post-Deepwater Horizon from 2017-05-30 to 2018-06-13

Abstract

As oil was deposited differentially within Chandeleur Island salt marshes, it provided the opportunity to investigate the long-term effect on the microbiology of oil-impacted areas containing co-occurring populations of black mangrove and smooth cordgrass. Genomic DNA was extracted from the top 0-7cm of sediment cores at five-time points over the course of 2 years (2017-2018) from two salt marsh locales within the Chandeleur Islands. Microbial community abundance and biodiversity were characterized with 16S rRNA using Illumina MiSeq 2x 250 bp technology for 60 samples. Samples data can be accessed at the National Center for Biotechnology Information (NCBI) under accession number PRJNA559553 (https://www.ncbi.nlm.nih.gov/bioproject/PRJNA559553).

Purpose

Paired-end reads from replicate samples provide a comprehensive view of microbial community composition and diversity in the northern Gulf of Mexico salt marsh seven and eight years after the Deepwater Horizon oil spill in sediment dominated by Spartina sp. (smooth cordgrass) or Avicennia germinans (black mangrove).
