Abstract: Anthropogenic N inputs have degraded Maryland's waters. However, the proportion of watershed N inputs lost to N removal processes is unknown. I am investigating stream export of total nitrogen and biogenic N gases (N2 and N20), evasion of biogenic gases from streams to the atmosphere, and the effect of storm flow on N export. Export and evasion of biogenic N gases from watersheds is poorly understood, but may represent a significant portion of anthropogenic inputs. This research will increase understanding of N transport and processing in Maryland watersheds, develop new methods, and improve watershed management.
