Plankton trophic dynamics in Chesapeake Bay: Models and budgets of carbon-nutrient coupling
Principal Investigator:

Horn Point Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
Description:
The objectives of this project are: to establish mass-balance constraints on planktonic trophuc fluxes through simulation studies and measures of net community metabolism (NCM); to calculate nutrient export/input for Bay regions and seasons in relation to NCM; to estimate particulate organic (POM) deposition for specific seasons and Bay regions; to relate spatial/temporal variations in NCM and POM deposition to changes in plankton trophic dynamics.

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.
