Abstract: ELM is an Estuarine Loading Model that calculates mean 
            annual concentration of dissolved inorganic nitrogen (DIN) 
            available to producers in shallow estuaries by considering 
            how different processes modify pools of nitrogen provided 
            by inputs (streams, groundwater, atmospheric deposition, 
            nitrogen fixation, and regeneration) and losses (burial and 
            denitrification), within components of the estuarine system 
            (bare sediments, seagrass meadows, salt marshes, water 
            column). ELM also considers the effect of flushing rate 
            within an estuary. Its formulation was constrained to 
            minimize demands of data needed to run the model. In spite 
            of simplifications, the model's predictions of mean annual 
            DIN were not significantly different than field 
            measurements done in estuaries on Cape Cod, Massachusetts, 
            subject to different rates of nitrogen loading.
