Harrison Research Group Global Change and Watershed Biogeochemistry

Due largely to human activities associated with food and energy production, the world is experiencing an un-precedented mobilization of nutrients such as nitrogen (N) and phosphorus (P). A substantial portion of this mobilized N and P flows into streams and rivers, and eventually down to coastal waters, where nutrient over-enrichment has been associated with a host of environmental impacts. En route to the ocean, these nutrients can alter ecosystem function as well as the balance of atmospheric greenhouse gases.

Our research group uses experimental, remote sensing, and spatially explicit modeling approaches to elucidate processes governing the mobilization, transport, transformation, and ecosystem/biogeochemical impacts of land-based N, P, and other bio-active elements.
