Research Abstract

In order to evaluate CO2 budget and ecosystem in the western subarctic Pacific, seasonal change s in phytoplankton abundance were observed by means of phytoplankton pigment analysis and cell-count to understand the physiological influences on the abundance in the upper layer off Kushiro, western Subarctic Pacific. Diatoms (larger cell size) were most abundant in the phytoplankton assemblage measured by pigments throughout the year although chrysophytes (small sized cell) were become dominant by cell-count particulary at offshore site. This reveals that water temperature was lower at offshore site than the coastal site because of low temperature preference of chrysophytes.
Seasonal changes in the carbon budget in the surface layer will be estimated near future because cell count is not completed yet on our whole samples.
