Abstract : A simulation model of the flow of the biologically limiting nutrient through the lower trophic levels (phytoplankton, zooplankton, pelagic fish, detritus), and limiting nutrient dissolved in the water column of a marine ecosystem over a continental shelf is presented. Interrelated processes of this time dependent, spatial, nonlinear, physical-chemical-biological model include advection, diffusion, several biotic and abiotic environmental conditions, and numerous biological processes. The maximum rate of nutrient uptake by phytoplankton, Vm, is found to be a fundamental time scale to which both physical and biological processes can be related. (Modified author abstract)
