Integrating tide-driven wetland soil redox and biogeochemical interactions into a land surface model

Coastal wetlands store large amounts of carbon and are sensitive to chemical interactions driven by salinity and tidal fluctuations • We coupled a land surface model to a reactive transport model to simulate biogeochemical cycling in saline and fresh tidal wetlands • Sulfate availability in saline wetlands lowered simulated methane emissions, which compared well with site measurements
