In 2003, an experimental corrosion platform was placed at the bow of the German submarine, U-166. This platform incorporated fifteen coupons including high carbon, low carbon steel, aluminum, and copper along with oak and mahogany wood coupons. This platform was recovered in 2014 and evaluated for microbiologically influenced corrosion. During the eleven years of deep ocean placement, the oak coupons degraded in four to six years while the mahogany disappeared after ten years. Biomass was...
Gulf of Mexico SCHEMA: Studying the Effects of a Major Oil Spill on Submerged Cultural Resources. Where Do We Go From Here? (2015)
As a result of this project, we better understand microbial communities' role in biofilm formation, wood degradation, and metal corrosion in the deep biosphere; however, new questions were raised. More information is needed to understand the ecosystemic role of shipwrecks and long-term impacts from oil spills. The diversity of micro- and macro- infauna and their response to environmental events indicates the suitability of shipwrecks as ecosystem monitoring platforms. Microbial response to...
Microbial Ecology of Gulf of Mexico Shipwrecks (2015)
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...
Microbiologically-Influenced Corrosion of Submerged World War II Plane Wrecks: Case Studies from Hawaiʻi (2023)
This is an abstract from the session entitled "Methods for Monitoring Heritage at Risk Sites in a Rapidly Changing Environment", at the 2023 annual meeting of the Society for Historical Archaeology. Archaeologists have increasingly examined the natural forces that threaten submerged cultural heritage resources. For metallic sites, such as sunken steamships and aircraft, corrosion has garnered a considerable amount of this interest. While general corrosion resulting from exposure to seawater...
