Figure 2 exhibit the migration pattern of one copepod-like functional species functional species with an unrealistic migration and diapausing pattern versus one that succeed to have a stable pattern throughout the 8 years of post spin-up simulations. The dates are the simulation dates and do not represent real life data. The reason why the biomass seems to decrease at when is migrate at depth is because, is only due to the height of the depth cell. In figure 2A, exiting mid-May/mid-June and going back into diapause in late September/mid-October, the first metazoan functional species takes five months to accumulate enough lipids to survive during the winter. In figure 2B, exiting in late-June/mid-July and going back in late-August/mid-September, the second metazoan functional species takes two month and a half to accumulate enough lipids in order to survive the winter season. Notwithstanding the timing difference between the two species, the maximum biomass at a given depth layer differs from one to two orders of magnitudes.
