Abstract
We carried out sensitivity analysis using ECOS3D model (Nakata ci al.. 2004) in order to investigate to influence what on the spatial distribution of nutrients (NO3, PO4). Net Primary Production (NPP). export (lux and CO2, fugacity (fO2) in the world ocean by changing parameter of phyloplankton of half saturation constants for PO4 and NO3 uptake, maximum cell-quota capacity (P-quota and N-quota). C/P and C/N ratio and minimum growth temperature. It revealed the possibility that small size phyloplankton may hardly to have cell-quota by comparing the model result with the observation data(WOA01) on nutrients. The model result on fCO2. NPP and export flux also showed the possibility that the activity of phyloplankton in high latitude region may influence on CO2 absorption assessment in the world ocean.
