NEMURO - A Biogeochemical component coupled to CCSR COCO 3.4 hydrodynamics and NEMURO biogeochemistry

Summary

NEMURO (North Pacific Ecosystem Model for Understanding Regional Oceanography) is a lower trophic level ecosystem model for the North Pacific Ocean.

NEMURO is a biomass-based Nitogen model that simulates the temporal evolution and dynamics of the North Pacific’s nutrient–phytoplankton–zooplankton food web. Different spatial implementations exist, including a single well-mixed domain that represents the surface layer of the water column (Kishi et al., 2006-a), a 1D vertically structured formulation (Fujii et al., 2006), a 2D cross-shelf formulation (Wainright et al., 2006), and a fully 3D spatially-explicit basin-scale implementation (Aita et al., 2006).

NEMURO is oupled to Center for Climate System Research (CCSR) Ocean Component Model (COCO Version 3.4) developed at CCSR, University of Tokyo (Hasumi, 2000, 2002). The horizontal resolution is one degree in both latitude and longitude and there are 54 vertical levels (same as Aita et al., 2003). There are 20 levels in the vertical each 5m thick within the upper 100 m, and 10m thick between 100m and 200 m.
