Drivers And Mechanisms Of Peat Collapse In Coastal Wetlands, Benjamin J. Wilson
Drivers And Mechanisms Of Peat Collapse In Coastal Wetlands, Benjamin J. Wilson
FIU Electronic Theses and Dissertations
Coastal wetlands store immense amounts of carbon (C) in vegetation and sediments, but this store of C is under threat from climate change. Accelerated sea level rise (SLR), which leads to saltwater intrusion, and more frequent periods of droughts will both impact biogeochemical cycling in wetlands. Coastal peat marshes are especially susceptible to saltwater intrusion and changes in water depth, but little is known about how exposure to salinity affects organic matter accumulation and peat stability. I investigated freshwater and brackish marsh responses to elevated salinity, greater inundation, drought, and increased nutrient loading. Elevated salinity pulses in a brackish marsh …
