Nitrogen source tracing in the Choptank River Watershed

This project analyzed existing aquatic sediments, plants, and animals collected throughout the watershed to pinpoint key sources of nitrogen. As submerged aquatic vegetation has disappeared in regions heavily impacted by land-use activities, macroalgae and oysters were deployed and incubated in situ to help trace the origin of nitrogen inputs by identifying, delineating and mapping the relative influence of the varied urban and agricultural land uses in the watershed.
