Dr. Tracy Quirk
(University of Delaware)
Dr. Quirk is a wetland ecologist interested in vegetation dynamics in coastal wetlands including factors that influence organic matter accumulation and decomposition and carbon and nutrient cycling. Her recent dissertation research was on the distribution of carbon and nitrogen pools in a salt marsh fringing a coastal lagoon and ecotypic variation of wetland plant species in biomass, carbon and nutrient allocation. Her current work includes establishing long‑term fixed station monitoring of tidal wetlands along the Delaware Estuary and Barnegat Bay. The goal is to relate factors of soil and water chemistry, plant biomass, hydrology, and elevation to wetland accretion rate to determine whether these wetlands will be able to maintain their elevation relative to sea level.
