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.

Assessing the Ecohydrological Performance of Stormwater Green Infrastructure (SWGI) Treatment Trains at the Subwatershed Scale in Montgomery County, MD
Urban stormwater runoff remains on the of the primary sources of nutrients, sediments, and other pollutants in receiving waters, like the Chesapeake Bay. Stormwater best management practices (BMPs) and green infrastructure (SWGI) have been implemented in urban and suburban areas to re-establish ecosystem functions lost because of urbanization. SWGI treatment trains provide sequential infiltration and treatment of stormwater on the landscape prior to export into nearby waterways and groundwater.
