| Outline of Final Research Achievements |
We have developed an analytical method for the stable isotope ratio of Ni, Cu, and Zn in seawater and developed a new chemical separation method for the precise isotope ratio analysis of Ni in rocks. We have established a new reference material for the Zn isotope ratio analysis through international collaboration. We have collected seawater samples during R/V Hakuho Maru cruises of KH-15-3 (the East China Sea) and KH-17-3 (the subarctic North Pacific). Using seawater samples collected during KH-14-6 (the Southern Ocean and the South Pacific), we have revealed sectional distributions of the concentration and stable isotope ratio for Ni, Cu, and Zn. We have mostly developed an analytical method for the concentration and stable isotope ratio of Mo and W in sediments. We have analyzed a sediment core collected from the middle depth bottom in the Japan Sea and several standard materials of rocks and sediments, pursuing the possibility of Mo and W as proxies for paleoceanography.
