Microbial Ecology of Gulf of Mexico Shipwrecks
Microbiomes associated with wooden and steel shipwrecks were investigated using next generation sequencing. Samples were derived from in situ biofilm monitoring platforms deployed for ~4 months, and sediment collected ~2-5 m from shipwrecks. The goal of the investigation is to determine rates of recruitment and community structure at sites located within and outside of areas impacted by the Deepwater Horizon spill (DWHS). Sediments will elucidate the influence of shipwrecks on the geochemistry and biodiversity of the surrounding seafloor. Taxonomic classification of dominant and rare members of shipwreck microbiomes and metabolic information extracted from sequence data yield new understanding of microbial processes associated with site formation. Physicochemical data helps describe features that shape shipwreck microbiomes. The study provides novel information on the identity of microbial inhabitants of shipwrecks, their role in site preservation, and impacts of the DWHS on the primary colonizers of shipwrecks in the deep ocean.
