| Outline of Final Research Achievements |
We have introduced the mechanism by which oceanic phytoplankton acclimatize to environmental changes into a numerical simulation and succeeded in significantly increasing the reproducibility of the observed biomass distribution. In the deep sea, where light is insufficient, phytoplankton acclimates to increase the amount of chlorophyll in their cells in order to increase the amount of light they acquire. By properly representing the acclimation process, we were able to improve the reproducibility of the chlorophyll distribution in the ocean. By introducing changes in the carbon/nitrogen ratio in phytoplankton cells due to acclimation, we were also able to improve the reproducibility of the distribution of carbon/nitrogen ratios in the ocean.
