Carbon dioxide fluxes and the dominant role of vegetation in recently created and reference Gulf Coast marshes by A. Muench, T. Elsey‐Quirk, J. R. White, R. D. DeLaune

“…Abstract Coastal wetlands are one of the most productive ecosystems on Earth with the capacity to sequester large amounts of carbon dioxide (CO2). Wetland loss due to anthropogenic and natural causes reduces the carbon (C) storage capacity and potentially releases previously fixed C in biomass and soil to the water column and atmosphere through decomposition. …”
