From a carbon management perspective, it is conservative to assume that a significant portion of the sunk biomass is remineralized and that water circulation and diffusion will distribute the dissolved carbon in the water reservoir. Depending on the circulation dynamics of the reservoir, some dissolved carbon may persist in stagnant deep water or stratified circulation. Any dissolved carbon that reaches the surface water will be brought into equilibrium with the atmosphere. The estimated timescale of this ventilation is dependent on the specific sinking location, which must be characterized at the project level but can be informed by models of the specific storage reservoir. The potential climate sensitivity of circulation dynamics is reservoir-specific and an outstanding area of uncertainty.
