These animations were created using output from a lower food web model linked to a three-dimensional hydrodynamic model. The lower food web was represented using a nutrient-phytoplankton-zooplankton-detritus (NPZD) model that included a quagga mussel (benthic filter feeder) bioenergetic model. The hydrodynamic model was the Finite Volume Community Ocean Model (FVCOM). The NPZD-mussel model was implemented using the General Ecological Module (GEM), which is part of the FVCOM code.
These animations were included in the supplemental material of a paper, additional details can be found there:
