High-resolution modelling of phytoplankton distribution and adaptation.

摘要: A state-of-the-art eddy-resolving ocean general circulation model has been coupled to a newly developed ecosystem and biogeochemical that attempts describe the physiology of phytoplankton cells, their adaptation changing external conditions separate cycling several nutrients (C, N, Si, Fe). In its initial state advection large number tracers in caused an increase MPI-exchange costs inhibited good scaling behaviour with increasing processors used. This overcome by bundling MPI exchange for all tracers. First results from show much improved representation small-scale biological features, e.g. along axis Antarctic Circumpolar Current, decoupling C N cycles nitrogen-limited subpolar gyres, increased Si:N ratio iron-limited regions.
