The influence of organic matter dynamics on the cycling of toxic organic contaminants in Chesapeake Bay
Principal Investigator:

Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
Description:
To relate the cycling of organic pollutants in Chesapeake Bay to seasonal changes in organic matter cycling and sediment transport. We will link compound-specific settling velocities, burial rates, resuspension fluxes, and benthic recycling rates to contaminant sorption and particle characteristics.

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.
