The nutrients-phytoplankton-zooplankton-detritus (NPZD) model was described by Ji et al. (2008) (Citation: Ji, R., C. Davis, C. Chen, and R. Beardsley, 2008. Influence of local and external processes on the annual nitrogen cycle and primary productivity on Georges Bank: A 3-D biological-physical modeling study. Journal of Marine Systems, 73:31-47. DOI: 10.1016/j.jmarsys.2007.08.002). Many key aspects of lower trophic level food web dynamics are described in this model using methods that are widely accepted in the marine ecosystem modeling community, including (1) Michaelis–Menten kinetics in nutrient uptake, (2) Holling type II functional response of zooplankton grazing on phytoplankton, (3) temperature/light-dependent growth for phytoplankton and temperature-dependent grazing and respiration for zooplankton, (4) self-shading of phytoplankton growth, and (5) sinking of phytoplankton and detritus.
