The FY 2001 is the final year of the present research and we have accomplished the followings. We carried out the 10 year long-term time-series sediment trapping in the Bering Sea and the central subarctic Pacific. In this FY, we focused on analyses on biogenic opal, calcium carbonate, and organic carbon and nitrogen of the fluxes for the latter half of the ten year's samples. Several important findings include, for example, unusually low total mass flux observed during 1997 and characteristically high fluxes observed during 1998 at Station SA in the central subarctic Pacific. We have completed writing of our synthesis manuscript entitled as "Long term monitoring of particle fluxes in the Bering Sea, 1990-1999, and the central subarctic Pacific, 1990-2000" by Takahashi et al., which has been accepted by Progress in Oceanograph. Furthermore, two significant chapters on Phaeodaria and Polycystine Radiolaria, which serve important particle tracers in the oceans, in "The Second Illustrated Guide to the Protozoa" have just been published.

2001财年是本研究的最后一年，我们完成了以下工作。我们在白令海和亚北极太平洋中部进行了10年的长期时间序列沉积物捕获。在本财年，我们重点分析了生物蛋白石，碳酸钙和有机碳和氮的通量的后半个十年的样品。一些重要的发现包括，例如，1997年在亚北极太平洋中部的SA站观测到的总质量通量异常低，而1998年观测到的通量却异常高。我们已经完成了Takahashi等人的题为“1990-1999年白令海和1990-2000年中亚北极太平洋粒子通量的长期监测”的综合手稿的撰写，这已经被海洋学进展所接受。此外，刚刚出版了《原生动物图解指南第二版》中关于海洋中重要的微粒示踪剂-棕囊藻和多胱氨酸放射虫的两个重要章节。
