Impact/Purpose:

We used a combination of multi-media modeling systems and chlorophyll α measurements to examine the drivers of the resurgence of HAB events in Lake Erie. The results reveal that reduced nitrogen (N) deposition and crop fertilization are strongly associated with chlorophyll a measurements. These results are unique because previous studies either do not consider deposition or only consider total deposition as measurements of dry N deposition are not available. This finding demonstrates the impact of a transitioning atmosphere from an oxidized to a reduced N state.

Description:

We used linked and coupled physical models to identify relationships among environmental variables across multiple sources and pathways to examine the impact of nitrogen loadings on chlorophyll α concentrations.
