Objective:
The objective of this research project is to: (1) develop a regional-scale model for analyzing nutrient inputs to coastal ecosystems; (2) to develop a classification scheme for the comparative analysis of the sensitivity of coastal ecosystems to these nutrient inputs; and (3) to develop quantitative approaches for evaluating how other stressors such as climate change, land-use change, and sediment fluxes interact with nutrient inputs to affect coastal ecosystems.
Progress Summary:
Progress to date has consisted of the preliminary development of a watershed-scale nutrient transport model and a nutrient-phytoplankton-zooplankton (NPZ) model of estuarine response to nitrogen loading, which we plan to use to develop a process-based estuarine classification scheme. Both of these models run in a spreadsheet platform, which makes these tools easy to disseminate.
Future Activities:
In the next year, we will: (1) further develop the watershed model and conduct preliminary testing in the Upper Susquehanna and other northeastern U.S. watersheds; and (2) further develop and analyze the dynamics of the NPZ estuarine response model and compare our findings with available estuarine datasets.
