Integration of an ecosystem module into the finite element sea-ice ocean model

摘要: In coupled ocean-biogeochemical models, the ocean model has a large influence on distribution of biological tracers. Biogeochemical models are traditionally to based finite difference method, but another option is employ an unstructured-mesh model. This makes it possible take advantage for instance aligning mesh with bathymetry or refining in areas interest without loss accuracy that nesting introduces. Here we present initial results coupling between Finite Element Sea-ice Ocean Model (FESOM) and biogeochemical REcoM2, special attention Southern Ocean. Surface fields nutrients, chlorophyll net primary production were compared available data sets focus spatial seasonal cycle. We saw produces realistic distributions, especially regarding mean surface concentration, whereas iron concentration became vey low Pacific, causing extensive limitation Area. The cycle was good agreement observations, spring blooms occurred too early Polar Regions. For showed this bloom caused by nutrient dominating area 40 60 degrees south. Light contrary main limiting factor seasonally ice covered south south, All all, similar performance other equal complexity well suited studies Ocean.
