Impact estimations of the ocean acidification on the calcium carbonate plankton in the Subarctic Pacific.

利用亚北极太平洋和南大洋的碳酸钙浮游生物对全球变暖引起的海洋酸化进行了影响评估实验。这些地区浮游植物的生物量和种类组成尚未完全确定。但是，可以清楚地看到，酸化对高生物量物种的影响更为明显。我们现在正在为这些证据提供理论依据。并且，我们现在同时关注酸化对硅藻的影响，硅藻是亚北极和南大洋的优势物种。

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.
