Conceptual Model: Biogeochemistry & Primary Production

Biogeochemistry and Primary Production

We anticipate a changing biogeochemical regime in the marsh, with the direction of change uncertain and variable due to complex interactions and feedbacks.
We expect to see changes in
     - salinity regime experienced by the marsh
     - primary production of marsh grasses
     - porewater chemistry and nutrient dynamics
     - carbon storage and export

driven by
      - increases in water and nutrient fluxes from the
      - increased porewater drainage from marsh edges
        and the creation of biogeochemical "hot spots"
      - increase in grazing as access to the marsh platform increases with rising sea level.
