基于硅藻和浮游有孔虫的定量分析，对北太平洋东部边缘中新世中晚中新世的古气候和古海洋学历史进行了研究。已经确定了14个冷事件和12个暖事件，这些事件与其他微化石研究以及来自低纬度太平洋遗址的氧同位素记录密切一致。3个参考位置的裂谷分别位于7 ~ 6.5 Ma、9.8 ~ 8.5 Ma和12 ~ 11 Ma，与世界海洋中公认的深海裂谷相对应。东北太平洋中新世中晚期古地温振荡
The paleoclimatic and paleoceanographic history of the Middle and Late Miocene marginal eastern North Pacific has been studied in a north-to-south transect encompassing DSDP Site 173, the Newport Beach surface section, and DSDP Site 470, based on quantitative diatom and planktic foraminiferal analyses. Fourteen cold and 12 warm events that show close agreement with other microfossil studies as well as oxygen isotope records from low-latitude Pacific sites have been identified. Hiatuses are recognized at 7 to 6.5 Ma, 9.8 to 8.5 Ma, and 12 to 11 Ma at the three reference localities, and they correspond to widely recognized deep-sea hiatuses in the World Ocean.
