| Summary: | Abstract This paper is intended to investigate of seasonal, annual and interannual variation of oceanic primary production by ocean color remote sensing data. In chapter 2, a two-phytoplankton community model based on the difference of productivity among the phytoplankton cell size was developed. In chapter 3, oceanic primary production was cal-culated by the two-phytoplankton community model and environmental data such as sea surface temperature, chlorophyll concentration and solar radiation from September 1997 to June 2001. The spatial, seasonal, annual and interannual variations of this time series of oceanic primary production were analyzed. Furthermore, relationships between pri-mary production and El Niño/Southern Oscillation in the Pacific Ocean were examined. In chapter 4, seasonal variation of chlorophyll concentration and primary production in the western North Pacific were analyzed. By cluster analysis of chlorophyll concentra-tion, the western North Pacific was divided into eight areas which showed original sea-sonal variation of chlorophyll concentration. Because these areas were corresponded to the Subtropical gyre, Transition domain and Subarctic gyre, the seasonal variations of chlorophyll concentration in western North Pacific was affected by physical conditions. |
