| Outline of Final Research Achievements |
Using ship-based time-series data, satellite observation data, and by ecosystem modelling, we investigated regionally specific spatial and temporal variations of biogeochemical and plankton biodiversity over the North Pacific. Based on the regional differences, we developed three new ocean provinces: “Biogeochemical Provinces”, “Chlorophyll a Provinces” and “Phytoplankton Diversity Provinces”. We particularly focused on the annual variation of boundary areas of each provinces as the regions which are potentially sensitive to environmental variations. Model projection on “Phytoplankton Diversity Provinces” suggested hot spots of biodiversity changes that are potentially induced by global warming in the end of 21st century. We expect that the outcome of this study can suggest better conservation and management options for marine special planning.
