Description:
In the lower Choptank estuary, we will identify the influence of temporal variation in organic matter loading and bottom water dissolved oxygen concentrations upon the rate of coupled nitrification/denitrification. We will compare our understanding of the sediment nitrogen cycle in the Choptank River to that in other Chesapeake subestuaries with different rates or sources of nitrogen inputs. Finally we will compare our understanding of the sediment nitrogen cycle in the Choptank River to that in other Chesapeake subestuaries with different rates or sources of nitrogen inputs.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
