Abundance changes in microfossil groups in the Japan Sea. Data has been used for diatoms in cores from ODP sites 794, 795, 796, and 797 (Koizumi 1992a), radiolarians from ODP site 794 (Itaki, unpublished data), calcareous nannofossils from ODP site 798 (Muza 1992), and benthic and planktonic foraminifera from ODP site 798 (Kato 1992) are illustrated. Opal (Dunbar et al. 1992) and calcium carbonate contents (Ingle Jr et al. 1990) from ODP site 798 are also shown
