Overall Modeling Approach

Circulation

• Semispectral Primitive Equation Model (SPEM)
  • three-dimensional
  • eddy resolving
  • no tidal dynamics

Prey

• Nutrient-Phytoplankton-Zooplankton model (NPZ)
  • zooplankton segregated by stage and/or species
  • include relevant prey items
  • fixed spatial grid (Eulerian)

Pollock

• Individual Based Model (IBM)
  • stochastic
  • egg, larval, and juvenile stages
  • spatially explicit; follow representative individuals
    through space and time (pseudo-Lagrangian)
