The present research used core samples and data provided by the Integrated Ocean Drilling Program (IODP) from Expedition 337. We deeply acknowledge the support provided by the staff and laboratory technicians aboard the D/V Chikyu and at the Kochi Institute for Core Sample Research (Japan Agency for Marine-Earth Science and Technology [JAMSTEC]). The present study was supported by the Japan Society for the Promotion of Science (JSPS) Strategic Fund for Strengthening Leading-Edge Research and Development (to JAMSTEC), the JSPS Funding Program for Next Generation World-Leading Researchers (NEXT Program; to Fumio Inagaki), and the JSPS through a Grant-in-Aid for Scientific Research (Number 25800284). We sincerely thank Tomaru Hitoshi for providing the interstitial pore water from Expedition 902. The data supporting this paper are available at the SIO7 Data Center (http://sio7.jamstec.go.jp).
