Description:
The primary objectives of this proposal are to apply a new direct measurement technique for denitrification to: examine approaches to determining system-wide denitrification estimates in the Choptank River subestuary and determine if oligohaline marshes are important sites for estuarine denitrification. Denitrification will be compared to N input terms available for this subestuary, as well as N sinks including marsh N storage and burial.

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.
