We studied high-resolution Quaternary calcareous nannofossil biostratigraphy to clarify the relationship between nannofossil events and oxygen isotope stratigraphy using the continuous sediment sequence from Integrated Ocean Drilling Program Site U1308 in the North Atlantic Ocean. Results indicate that some nannofossil events found in the section, such as the last occurrences of Reticulofenestra asanoi and Gephyrocapsa spp. (large), are located in a different stratigraphic position compared to previous studies. We also clarify the critical stratigraphic positions of both the first occurrence of Emiliania huxleyi and the last occurrence of Pseudoemiliania lacunosa, which occur just below the highest peaks of each marine isotope Stage 8 and 12.
