Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes Predicted carbon fluxes in Lake Maurepas swamp forests under various hydrologic and salinity regimes

A process-driven biogeochemistry model, Wetland Carbon Assessment Tool - DeNitrification-DeComposition model (WCAT-DNDC) was validated and applied to examine the responses of daily net ecosystem exchange (NEE), net primary productivity (NPP), ecosystem respiration (ER), methane (CH4) and nitrous oxide (N2O) emissions in the Lake Maurepas swamp forests under dry (2011), normal (2019), and...
