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

*** denotes optional material
