从冲绳海槽和南中国海打捞的岩心 255、170、17940-2 已被研究为浮游有孔虫。其中，Plleniatina obliquiloculata 对西太平洋晚第四纪冬季海面温度敏感。其相对丰度波动显着并且在核心之间具有相关性。全新世最显着的变化是距今 4-2ka B. P. 左右的 P. obliquiloculata 极小区，这可能与新冰期变冷有关。这种降温事件在西太平洋的广泛发生表明，P. obliquiloculata 有希望成为古海洋和气候监测者，可能对重建海陆气候相关性很重要。
Cores 255, 170, 17940-2, raised from the Okinawa Trough and South China Sea, have been studied for planktonic foraminifers. Among all the species, Pulleniatina obliquiloculata is shown to be sensitive to winter sea surface temperature in the late Quaternary in the western Pacific. Its relative abundance fluctuations are significant and correlatable between the cores. The most conspicuous change during Holocene is the P. obliquiloculata minimum zone around 4-2ka B. P., which correlates probably to the neoglacial cooling. The widespread occurrence of this cooling event in the western Pacific suggests that P. obliquiloculata is promising as a paleoceanographic and climatic monitor, possibly important for reconstructing sea-land correlation of climate.
