| Research Abstract |
Impact estimation experiments of the ocean acidification being caused by the global warming were carried out using calcium carbonate plankton in the Subarctic Pacific as well as in the Southern Ocean. Biomass and species compositions of phytoplankton (haptophytes: coccolithopholids) in these areas are not completed yet. But, it is clearly observed that the acidification impacts were more obvious on the higher biomass species. We are now making theoretical buck grounds for these evidences. And, we now pay simultaneously attentions of the acidification impacts on the diatoms, dominant species in the Subarctic and Southern Oceans.
