Assess graduate-level understanding of how water-table dynamics control hydrological and biogeochemical processes that determine peatland carbon fluxes, including mechanisms linking water-table depth to aerobic vs. anaerobic decomposition, CO2 and CH4 production and emission, DOC mobilization, redox gradients, and microbial pathways; require interpretation of simple flux and water-table data, evaluation of experimental and modeling approaches for drying/wetting scenarios, and discussion of implications for carbon balance and greenhouse-gas management.
