Research Topic: Quantifying the impact of urbanization on N and P inputs, transformations, removal and fluxes in watersheds draining to the Plum Island Estuary

Advisors: Dr. Wilfred Wollheim and Dr. William McDowell


Description of Research


I am interested in understanding the role that river networks play in mitigating nutrient inputs from suburban areas. Previous research has established that higher nutrient inputs impact downstream rivers, lakes and coastal zones by causing eutrophication and harmful algal blooms.  My research is focused on watersheds that drain to the Plum Island Estuary and are part of the Plum Island Ecosystems Long Term Ecological Research (LTER) site. I am specifically looking at how in-stream nutrient dynamics in small, headwater streams in suburban neighborhoods compare with similar streams in forested watersheds.  Furthermore, by using the long-term data record for the Ipswich and Parker Rivers, I am exploring how these changes are affecting long term changes in nutrient inputs to the Plum Island Estuary.
