Microphytobenthic community and microelectrode profile responses in oiled coastal marine sediment microcosms, based on samples collected at Chandeleur Island, Louisiana and Estero Bay, Florida in 2017

The Deepwater Horizon oil spill impacted tidal flats in the Gulf of Mexico. This collection of datasets is generated from oiled tidal flat microcosms to examine the oil spill responses on benthic algal communities. Genomic DNA was extracted from the surface sediment cores. The abundance and biodiversity of microphytobenthic communities were characterized based on the 23S rRNA gene using Illumina MiSeq 2x 250 bp technology.
