| Abstract: | The set of equations for global ocean biogeochemistry deterministic models have been formulated in a comprehensive and
unified form in order to use them in numerical simulations of the marine ecosystem for climate change studies (PELAGOS,
PELAgic biogeochemistry for Global Ocean Simulations). The fundamental approach stems from the representation of marine
trophic interactions and major biogeochemical cycles introduced in the European Regional Seas Ecosystem Model (ERSEM). Our
theoretical formulation revisits and generalizes the stoichiometric approach of ERSEM by defining the state variables as Chemical
Functional Families (CFF). CFFs are further subdivided into living, non-living and inorganic components. Living CFFs are the
basis for the definition of Living Functional Groups, the biomass-based functional prototype of the real organisms. Both CFFs and
LFGs are theoretical constructs which allow us to relate measurable properties of marine biogeochemistry to the state variables
used in deterministic models. This approach is sufficiently generic that may be used to describe other existing biomass-based
ecosystem model. |
