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:

$$H_3PO_4 +\alpha HNO_3 + \beta CO_2 + \lambda H_2 =C_\beta H_\zeta O_\psi N_\alpha P + \gamma O_2$$

where the coefficients α, β, and γ are related to the Redfield ratio.

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. 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
