Main Article: Remineralization
My focus: Remineralization in Sediments
a). Reactions
The process of remineralization of organic matter through the consumption of nutrients by organisms is given by:
where the coefficients α, β, and γ are related to the Redfield ratio.[1]
b). Redox Zonation
Redox zonation refers to how the processes that transfer terminal electrons as a result of organic matter degradation vary depending on time and space. [2] The sequence in which these processes occur are a function of a partial equilibrium process rather than the total energy yield of the processes themselves.
i). Oxic
ii). Anoxic
c). Solute Transport
i). Advective/Diffusive Transport
ii). Role of Bioturbation
d). ***Sediments as a biogeochemical pump/controller
