Preliminary simulations form the coupled NEMO-PISCES-APECOSM (NPA) model from 1958 to 2018
APECOSM is a mechanistic 3D size-structured integrated ecosystem model developed by the IRD team in SUMMER. In the SUMMER project, it is coupled two-ways to the ocean-biogeochemistrery model NEMO-PISCES to investigate the biomass distribution and dynamics of mesopelagic organisms, their role in the biological carbon pump and the potential impacts of their exploitation in a climate change context. The animation shows the biomass of three communities integrated over the [1mm ; 2m] size range, from the surface to the bottom of the ocean.
