对取自冲绳海槽和南海的3个重力柱状样(255,170,17940-2柱状样)进行浮游有孔虫分析后发现:所有属种中,Pulleniatina obliquiloculata显示出对西太平洋晚第四纪冬季表层海水温度反应灵敏,其相对丰度的变化显著,且在各柱状样间可以对比。全新世最显著的变化是约4～2kaBP前的P. obliquiloculata最小值带,可能与新冰期变冷有关。这一变冷事件在西大平洋的广泛存在表示P obliquiloculata可以作为古海洋和气候变化的示踪器,对于海-陆气候对比亦较重要。
Planktonic foraminifera analysis of three gravitational column samples (columns 255, 170, 17940-2) taken from the Okinawa Trough and the South China Sea found that among all the species, Pulleniatina obliquiloculata showed a significant contribution to the winter Quaternary in the western Pacific Seawater temperature was sensitive and its relative abundance changed significantly, and it could be compared among the columnar samples. The most significant change in the Holocene is the minimum value of P. obliquiloculata before about 4 ~ 2 ka BP, which may be related to the cooling in the New Ice Age. The widespread presence of this chilling event in the Western Great Ocean indicates that P obliquiloculata can serve as a tracer of paleoceanography and climate change and is also important for sea-land climate comparisons.
