3-daily averaged sea surface temperature, ocean currents (u, v), nitrate and phytoplankton biomass for the 35 types in the top 10m of the model. Model output has been interpolated from the natural grid onto 1/5th degree resolution. This version of the model was run with the gud package (git:// The ecosystem model is based on Dutkiewicz et al (2015, 2019) and resolves the cycling of carbon, phosphorus, nitrogen silica, iron, and oxygen through inorganic, living, dissolved and particulate organic phases (including CDOM). The biogeochemical and biological tracers are transported and mixed by the MIT general circulation model (MITgcm, Marshall et al., 1997). The three dimensional configuration used here has nominally 18km horizontal resolution and 50 levels ranging from 10m in the surface to 500m at depth (the ECCO2 CS510 physical simulation, Menemenlis et al 2008). The model resolves 35 phytoplankton types, covering several functional groups (picophytoplankton, coccolithophores, diazotrophs, diatoms, mixotrophic dinoflagellates), 16 size classes (from 0.6 to 228um equivalent spherical diameter). There are 16 grazer size classes from 6.6 to 2280um equivalent spherical diameter. The phytoplankton types differ in the types of nutrients they require (e.g. diatoms require silica), maximum growth rate, nutrient half saturation constants, sinking rates, and palatability to grazers. Plankton growth, grazing and sinking parameters are linked to size following the allometric scaling used in Dutkiewicz et al (2019).
