Dr. Leila Hamdan led a research team which included three ESP students on the third oceanographic expedition of the Gulf of Mexico-SCHEMA project (Shipwreck Corrosion, Hydrocarbon Exposure, Microbiology and Archaeology).  The expedition occurred on the Research Vessel Pelican, operated by the Louisiana Universities Marine Consortium.   The study, primarily supported by the Bureau of Ocean Energy Management (BOEM), continues to investigate the impact of the 2010 Deepwater Horizon spill on shipwreck sites and their associated microbial infauna in the Gulf of Mexico.  On this third leg, project participants collected sediment samples from around each shipwreck using a Multicorer outfitted with a camera system (provided by Woods Hole Oceanographic Institution).  Over the next few months, researchers on this project will evaluate changes in microbial community structure and function as a result of exposure to spill related contaminants.  Of key interest is how any changes may impact the longevity of shipwrecks in the deep ocean.

GMU scientists were joined by researchers from the Naval Research Laboratory, University of Texas Marine Science Institute, and American University.
