The Wetlands Section focuses on evaluating the functions and services of tidal freshwater wetlands and brackish and salt marshes, and how these ecosystems are affected by and respond to anthropogenic changes (e.g., sea level rise, mosquito control, nutrient inputs, and climate change). Research includes examining nutrient and carbon cycling, storage in wetland plants and soils, and the exchange of these elements between the plants, soil, water, and atmosphere.
Specific projects within the Wetland and Biogeochemistry sections include the development and coordination of an intensive long-term monitoring program in wetlands along the Delaware Estuary and Barnegat Bay, NJ. The Patrick Center is partnered with two National Estuary Programs, the Partnership for Delaware Estuary and the Barnegat Bay Partnership, along with other federal, state, and academic partners to implement evaluation of elevation, water and soil chemistry, plant composition, and biomass changes over time in over seven wetlands of the Delaware Bay and three wetlands in Barnegat Bay.

Google Scholar Profile
- Dr. Elizabeth Watson is a wetland scientist interested in the responses of coastal estuaries and to human impacts and climate change, and the role of wetlands in global biogeochemical cycles. Current projects include the implementation and success of coastal climate-adaptation strategies in southern New England, developing indicators of nutrient enrichment for Long Island, NY estuaries, using CT scans to visualize belowground biomass of wetland plants, toxicological effects of macroalage, and the 150-year reconstruction of cumulative nitrogen pollution in Narragansett Bay, Rhode Island.

- Kirk Raper, M.S.
Mr. Raper is the wetlands project coordinator for the Academy of Natural Sciences. Mr. Raper is the lead scientist for monitoring marsh elevation change, sediment deposition and accumulation, plant distribution patterns and biomass, soil chemistry, sediment availability and nutrient concentrations in ten coastal wetlands located in Delaware and Barnegat Bays.
