Details of the late Miocene paleoceanography of the Japan Sea (10–5 Ma). We compare relative abundances of C. nakasekoi, Tetrapyle spp., and C. papillosum from Sites U1425 and U1430 between 9.5 and 7 Ma. The interval between 7.0 and 5.0 Ma shows relative abundance of Phorticium spp. and species related to subarctic water (the selected species are listed at the upper right in the figure). These data are compared to oxygen and carbon isotope data for planktic and benthic foraminifer obtained from the South China Sea (ODP 1146, Holbourn et al. 2018)
