Long-term biogenic particle fluxes and the global environmental change

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年长期时间序列沉积物捕获。在本年度，我们重点分析了十年后半期样品的生物成因蛋白石、碳酸钙和有机碳氮的通量。若干重要发现包括，例如，在亚北极太平洋中部的SA站，1997年观测到的总质量通量异常低，1998年观测到的通量异常高。我们已经完成了Takahashi等人撰写的题为“1990-1999年白令海和1990-2000年亚北极太平洋中部颗粒通量的长期监测”的综合稿件，并已被《Progress in Oceanograph》接受。此外，在《第二原生动物图解指南》中，关于在海洋中充当重要粒子示踪剂的Phaeodaria和Polycystine Radiolaria的两个重要章节刚刚出版。

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.
