description

Carbon fluxes are the movement of Carbon from one place (Source) to another (Sink). Carbon fluxes all have dimensions of {mass or amount of} Carbon per area (or volume) per time. Biochemically-oriented projects use moles (e.g., for Stoichiometry) rather than kg to quantify the amount of Carbon, whereas Climate-oriented projects use kg. When a system contains two or more components whose concentration vary from point to point, there is a natural tendency for mass to be transferred, minimizing any concentration difference within the system. Mass Transfer in a system is governed by Fick's First Law: 'Diffusion flux from higher concentration to lower concentration is proportional to the gradient of the concentration of the substance and the diffusivity of the substance in the medium.'
