Japan Drilling Earth Science Consortium

The Japan Drilling Earth Science Consortium is a coordinating body for scientific ocean and continental drilling activities linking institutions such as University of Tokyo, Japan Agency for Marine-Earth Science and Technology, National Institute of Advanced Industrial Science and Technology, Tohoku University and Kyoto University. It supports interdisciplinary programs involving organizations like Japan Society for the Promotion of Science, Ministry of Education, Culture, Sports, Science and Technology (Japan), Japan Science and Technology Agency, Geological Survey of Japan (AIST), and National Institute of Polar Research to advance studies in tectonics, volcanology, seismology, paleoclimate, and sedimentology.

Overview

The Consortium provides strategic coordination among research centers such as Ocean Research Institute, University of Tokyo, Kobe University, Hokkaido University, Kyushu University, Nagoya University and international partners including Integrated Ocean Drilling Program, International Ocean Discovery Program, IODP USSSP, and European Consortium for Ocean Research Drilling. It facilitates expeditions, data sharing, and training with agencies like Japan Meteorological Agency, Agency for Cultural Affairs (Japan), Japan Atomic Energy Agency, and museums such as the National Museum of Nature and Science. Stakeholders include research councils, laboratories, and field stations such as AIST Tsukuba, JAMSTEC Kochi Core Center, Kochi University, and Waseda University.

History and Formation

The Consortium emerged amid collaborations between institutions including Imperial College London partners and Japanese entities after initiatives by JAMSTEC and University of Tokyo scientists who coordinated with international programs like Deep Sea Drilling Project, Ocean Drilling Program, and Integrated Ocean Drilling Program. Early meetings involved representatives from Tohoku University, Hokkaido University, Kyoto University, Nagoya University, Osaka University, Kanazawa University, and organizations such as Geological Survey of Japan (AIST), Japan Society for the Promotion of Science, and Ministry of Education, Culture, Sports, Science and Technology (Japan). The Consortium's formation paralleled large projects including the Nankai Trough Seismogenic Zone Experiment and initiatives aligned with the Great East Japan Earthquake research response.

Research Programs and Projects

Programs coordinated through the Consortium include drilling campaigns related to the Nankai Trough, Japan Trench, Ryukyu Arc, Izu-Bonin-Mariana Arc, and continental projects in regions near Fossa Magna and Shimokita Peninsula. Projects have examined links to phenomena studied by Japan Meteorological Agency, High Energy Accelerator Research Organization (KEK), and paleoclimate signals comparable to records from Lake Biwa and Lake Suigetsu. Major scientific themes connect to work on subduction zone megathrusts, slow slip events, paleotsunami deposits, methane hydrate, and deep biosphere studies akin to international programs at IODP and ICDP (International Continental Scientific Drilling Program). Collaborative campaigns involved partners like University of California, Santa Cruz, Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, Borehole Research Group, and British Geological Survey.

Organization and Membership

Members include universities and institutes such as University of Tokyo, Tohoku University, Hokkaido University, Kyoto University, Nagoya University, Osaka University, Kobe University, Kyushu University, Waseda University, Keio University, and national laboratories including JAMSTEC, AIST, National Institute of Advanced Industrial Science and Technology, National Institute of Polar Research, and museum partners like the National Museum of Nature and Science. International affiliates include IODP, ICDP, Integrated Ocean Drilling Program, European Consortium for Ocean Research Drilling, Geological Survey of Japan (AIST), and research centers such as IFREMER and GEOMAR. Governance often involves advisory boards with representatives from Japan Society for the Promotion of Science, Ministry of Education, Culture, Sports, Science and Technology (Japan), and international scientific committees like SCAR and SCOR.

Facilities and Infrastructure

The Consortium leverages facilities including core repositories at JAMSTEC Kochi Core Center, well-equipped laboratories at University of Tokyo, petrology and geochemistry labs at Tohoku University and Hokkaido University, and drilling platforms such as research vessels operated by JAMSTEC and equipment similar to rigs used by Chikyu and platforms used in IODP expeditions. It uses seismic networks coordinated with Japan Meteorological Agency and borehole observatories linked to projects like the Muroto Observatory and observatories associated with NIED (National Research Institute for Earth Science and Disaster Resilience). Analytical capacity includes mass spectrometers and facilities comparable to those at RIKEN and KEK.

Funding and Collaborations

Primary funding sources include national agencies like Ministry of Education, Culture, Sports, Science and Technology (Japan), Japan Society for the Promotion of Science, Japan Science and Technology Agency, and institutional support from JAMSTEC and universities such as University of Tokyo, Tohoku University, and Kyoto University. International partnerships involve IODP, ICDP, European Consortium for Ocean Research Drilling, National Science Foundation (United States), Natural Environment Research Council, and bilateral collaborations with institutions including Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, University of Cambridge, ETH Zurich, CNRS, and GEOMAR. Collaborative frameworks have supported responses to events like the 2011 Tōhoku earthquake and tsunami.

Impact and Contributions to Earth Science

The Consortium has enabled drilling campaigns that contributed to understanding subduction zone earthquakes, megathrust rupture processes, paleoseismology, tsunami deposits, methane hydrate stability, and deep microbial ecosystems, linking results to international studies from IODP and ICDP. Outputs have informed hazard assessments used by agencies such as Japan Meteorological Agency and NIED, and have been cited in publications involving researchers from University of Tokyo, Tohoku University, JAMSTEC, Kyoto University, Hokkaido University, Nagoya University, and international collaborators like Woods Hole Oceanographic Institution and Scripps Institution of Oceanography. The Consortium's role in fostering cross-institutional drilling, data stewardship, and training has strengthened ties among research institutions including AIST, RIKEN, KEK, JAMSTEC, NSF, and European partners, advancing global knowledge of plate tectonics, seismogenesis, and Earth system history.
