Description:
The objectives of this research are to reliably measure the direct fluxes of trace elements across the sediment-water interface of field-collected cores, measure temporal and spatial variability of such fluxes and determine the importance of Mn, Fe and S redox cycling on trace element production and consumption. This project will determine whether the recycling of metals within surficial sediments has an important impact on water column metal concentrations.

Exploring the Use of Benthic Microbial Fuel Cells to Remove Sulfide While Harvesting Energy from Oyster Aquaculture Biodeposits
Oyster aquaculture is a rapidly growing industry in Maryland’s Chesapeake waters which stimulates economic activity and may provide a host of ecosystem benefits. A potential concern associated with the intensification of the oyster aquaculture is the local production and accumulation of oyster biodeposits, which can lead to a porewater sulfide accumulation and declining bioturbation, symptoms of declining ecosystem function. Sulfide is naturally removed from the seafloor by the interactions between bioturbating infauna and sulfide oxidizing bacteria.
