因子分析的南极有孔虫组合分析从西北太平洋附近的日本沉积物样品中定义了五个主要因素，包括黑潮，过渡水，Oyashio，黑潮环流边缘和沿海水域的因素，映射时，显示出独特的分布。这些因素占总方差的94%以上。在回归分析中，每一个因素都可以作为自变量处理。冬季和夏季的海面温度（SST）的相关因素的方程显示出很高的精度。本研究建立的传递函数方程PFJ-125对冬季温度的估计标准误差约为±1.75°C，对夏季温度的估计标准误差约为± 1.1TC。传递函数PFJ-125被应用到代表过去12万年的组合。在活塞芯C-1收集在该地区的常磐，东北本州，日本。在10，500年B. P.时，冬季SST最低估计值为4.1°C，夏季SST最低估计值为1B.5°C，而在6，300年B. P.时，冬季SST最高估计值为12。BOC和23.9°C在夏天。根据估计冬季的核心变化。和夏季SST和波动的五个已确定的因素负荷，C-1核心站点交替的影响下，通过过去的12 K Yl '和海洋条件在核心站点C-1在10，500年B. P.是可比的记录在同一地区的末次盛冰期。
Factor analysis of planktic foraminiferal assemblages analyzed in sediment samples from the Northwest Pacific Ocean near Japan defines five major factors including the Kuroshio, Transitional Water, Oyashio, Kuroshio Gyre Margin and Coastal Water factors which, when mapped, show distinctive distributions. These factors account for over 94% of the total variance. Each of the factors can be treated as an independent variable in a regression analysis. Equations relating factors to winter and summer seasurface temperatures (SSTs) show a high degree of accuracy. The standard errors of estimate for the transfer function equations PFJ-125 established in this study average about ±1.75°C for estimated winter temperatures, and about ± 1.1TC for summer temperatures. Transfer functions PFJ-125 were applied to assemblages representing the last 12 K yrs. in piston core C-1 collected in the area off Joban, northeast Honshu, Japan. The lowest estimated winter SST is 4.1°C and 1B.5°C for the summer SST at 10,500 yrs. B.P. whereas at 6,300 yrs. B.P. the winter highest SST is 12. BOC and 23.9°C in the summer. Based on down-core variations in estimated winter. and summer SST and fluctuations of the five identified factor loadings, the C-1 core site was alternatively under the influence of the Oyashio and Kuroshio Fronts through the last 12 K Yl'&Marine conditions at core site C-1 at 10,500 yrs. B.P. are comparable with those recorded in the same area for the last glacial maximum.
