My Science Topics
My USGS Science Strategy AreasUnderstanding Ecosystems & Predicting Ecosystems Change
Coastal and Estuarine Ecology
My research focuses on understanding and predicting responses of estuarine and wetland systems to various human and natural stressors, with the ultimate goal of informing conservation and management decisions in coastal environments. Recent areas of emphasis include developing appropriate indicators and approaches for seagrass, estuarine, and salt marsh ecosystem monitoring and assessment at local and regional scales; determining the impacts of some common commercial fishing practices on New England eelgrass habitats; and quantifying relationships between nutrient loading and the integrity of seagrass ecosystems. My earlier research experience includes investigations of seagrass ecosystems in Chesapeake Bay and the Gulf of Mexico.
