Presentation transcript:

Inorganic Nutrient Research Baltimore Ecosystem Study LTER BES LTER Long-term studies of nitrogen concentration and retention along an urban-rural gradient

Recent Key Findings - Inorganic Nutrients BES LTER Nitrogen retention varies with land use and climate Bettez et al. (In Review)

Syntheses ideas - Inorganic Nutrients BES LTER Bayesian Network Model (LaDeau et al) Using long-term data to explore multiple drivers of nitrogen flux and retention Model allows us to learn about drivers of watershed N retention and make predictions (or not) The data and the coupling of nitrogen dynamics in a hierarchical modeling framework highlights what controls the flux of inorganic material from watersheds to the Chesapeake Bay which has developed a total maximum daily load (TMDL) program.
