Atmospheric Deposition of Phosphorus across the Great Lakes Region
This project will investigate and assess levels of phosphorus deposited from the atmosphere across the Great Lakes region. While atmospheric phosphorus may contribute a significant portion of soluble reactive phosphorus to lake ecosystems, the relative scale of phosphorus emissions to the atmosphere, and the relative proportions of dry and wet phosphorus deposition are poorly characterized for many lakes. More measurements, as well as the development of deterministic atmospheric models, are needed. Our team will investigate three primary aims: 1) assessment of the spatial and temporal variability of atmospheric phosphorus deposition through measurements, 2) comparison of measurements with deposition estimates from deterministic atmospheric modeling, 3) assessment of quantified atmospheric phosphorus deposition relative to total load from all pathways.
