Salt Marshes Biogeochemistry
Salt marshes, which exist at the boundary between the terrestrial and marine environments, are highly productive coastal wetlands that serve a critical role in carbon sequestration and nutrient trapping. In the East Anglian (UK) salt marsh sediments, we find overall two broad sediment chemistries: iron-rich sediment, which is characterized by high ferrous iron concentration (up to 2mM) and sulfide-rich sediment, which is characterized by high sulfide concentrations (up to 8 mM) and high methane concentrations.
