Wetland Biogeochemistry Laboratory


Conducts research and develops programs in areas of aquatic and soil biogeochemistry and ecology, including biogeochemical cycling of organic carbon and other nutrients in wetland soils and aquatic ecosystems, role of organic matter as driver and modulator of wetland ecosystem functions, role of aquatic vegetation in DOM/POM/nutrient dynamics and soil accretion, fire ecology of wetlands and impacts to biogeochemical cycles and ecosystem responses, soil subsidence, coastal processes with respect to seagrass and mangrove productivity and organic matter cycling, sub-aqueous soil pedogenisis, soil biogeochemical processes associated with coastal forest retreat and development of salt marsh ecosystems, wetland soils as natural water quality treatment systems. New research directions include intensive soil studies on hard clam aquaculture leases, which allows for a novel application of soil science to new aquatic ecosystems.
