Correlation of Upper Pliocene - Lower Pleistocene Nannofossil Datums with Oxygen Isotope Stratigraphy

这项研究将校准高分辨率氧同位素 中国17个深海测点上新世-早更新世地层 太平洋、大西洋和印度洋， 超微化石基准事件 它将建立同步性或 这些基准事件的历时性，并导致更精确的 生物年代地层学在这一关键时期的意义 古生态学、古海洋学和气候解释。

This study will calibrate a high resolution oxygen-isotopic stratigraphy of Pliocene-early Pleistocene of 17 deep sea sites in the Pacific, Atlantic, and Indian Oceans with calcareous nannofossil datum events. It will establish the synchroniety or diachroniety of these datum events and lead to a more precise biochronostratigraphy for this critical interval for meaningful paleoecological, paleoceanographic and climatic interpretations.
