Earth and Planetary Sciences CourseEarth Environmental SystemsGeology and GeobiologyGeochemistry and CosmochemistryEarth and Planetary PhysicsMasao Takano / Yasuhiro Hirano / Takafumi MiyasakaWe view the Earth’s environment as a result of complex interactions between nature and human activities, and carry out research and education on its sustainability from this systemic viewpoint. Our research and education topics include, but are not limited to, developing sustainable regions with the use of natural energy, evaluating environmental impacts on underground ecosystems in forest areas, and understanding social‒ecological systems to combat desertification and manage protected areas in a sustainable way. We promote interdisciplinary and transdisciplinary approaches in collaboration with academics in various fields and non-academics, including practitioners and policy makers.Makoto Takeuchi / Katsuyoshi Michibayashi /Satoshi Takahashi / Marc Humblet / Seiji Hayashi / Yui KoketsuBased on traditional knowledge of geology and paleontology, this laboratory carries out research and education concerning the Earth’s history on a long time scale. The main themes of our research and education are: 1) to analyze the tectonics of the crust and the mantle, as well as their interaction, using analytical methods such as field work and instrumental analysis, focusing on sedimentation, metamorphism, material cycling in the deep Earth, and geochronology, and 2) to analyze the evolution of the biosphere and its interaction with the global environment using analytical techniques in the fields of paleontology, evolutionary biology, sedimentology and geochemistry.Hiroshi Hidaka / Yasuhiro Hirahara / Koichi Mimura / Yoshihiro Asahara / Minako Hashiguchi This laboratory aims to analyze the global environment, including human activities, using various chemical compounds, chemical elements and isotopes. To accomplish this, it is necessary to trace the history of the evolution of materials, including biological activities, over the past 4.6 billion years, since the formation of the solar system. Currently, the laboratory is engaged in research and education in three main fields: 1) cosmochemistry, studying extraterrestrial materials such as meteorites and lunar samples, 2) geochemistry, studying terrestrial materials, and 3) environmental chemistry, studying the interaction between human activities and terrestrial materials.Sei-ichiro Watanabe / Hiroyuki Kumagai / Sin-iti Shirono / Atsuko Namiki The aim of this laboratory’s education and research is to explore the origin of the solar system and the evolution/changes occurring on the Earth and other planets by physically analyzing various phenomena relating to the Earth and the other planets constituting the solar system. Three key themes of our research are: 1) to explore the mechanism responsible for the formation and variation of the solar system and the environments of the Earth/planets from a comparative planetology perspective, involving the theory of solar system formation, and 2) to explore the crustal movements, earthquakes and volcanic activities associated with the solid Earth, and the dynamics of the Earth’s interior, by utilizing a modeling approach to solid-Earth cycles. 3) to explore the geophysical phenomena from the viewpoint of the fundamental physics of complex fluid matter.
