根据2002年6月至2003年5月在日本本州岛北方海域进行的沉积物捕获实验，研究了太平洋西亚北极环流远西部放射虫通量的季节变化。与日本海的津轻暖流（TGC）有关的暖水和浅海种占优势，而与亲潮寒流有关的冷水种相对较少，尽管该地点位于亚北极省。R型聚类分析用于将物种特定的通量模式分为5组动物群，与以下相关：（1）2002年6月的TGC先导流;（2）2002年9 - 11月的TGC主流;（3）2002年12月的浅海流;（4）2003年5月的亲潮寒流;（5）2002/2003年春季的表层生产力和2002年夏季的TGC。(C)2008 Elsevier B. V. Ail版权所有。
Seasonal changes of radiolarian flux in the far western area of the Western Subarctic Gyre in the Pacific Ocean were examined based on samples from a sediment-trap experiment deployed at a site off the northern Honshu Island of Japan from June 2002 to May 2003. Warm and neritic water species associated with the Tsugaru Warm Current (TGC), originating from the Japan Sea, Were dominant, while the cold-water species associated with the Oyashio Cold Current were relatively few, in spite of the location of the site in the subarctic province. R-mode Cluster analysis was used to divide species-specific flux patterns into 5 groups of fauna associated with: (1) the TGC forerunner in June 2002, (2) the TGC main flow from September to November 2002, (3) the neritic water in December 2002, (4) the Oyashio Cold Current in May 2003 and (5), surface productivity in the spring of 2002/2003 together with the TGC in Summer 2002.
