Description:
The goal of this project is to develop and test a new approach to examine the degree to which methods used for mitigation and remediation of wetland and estuarine sediments reduce the transfer of contaminants to the environment. We will compare and contrast three proposed mitigation strategies: capping, phytoremediation, and marsh restoration using contaminated sediments.

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.
