The biological pump plays a major role in limiting the atmospheric concentrations
of CO
, through photosynthetic processes, but the transfers of carbon inside the
biological pump are still poorly quantified, largely because of the complexity and
uniqueness of most marine food webs. For example, no less than 36 different
carbon compartments characterize the Chesapeake Bay ecosystem. Quantification
of the standing stock and transfer rates for each and every compartment is
necessary before the direct and indirect consequences of an external physical
