Earth Environmental Systems	From the viewpoint of earth environmental system science, this laboratory is carrying out research and education on the earth's environment formed as a result of interaction between nature and anthropologic activities. Earth, planetary and space environments, and their temporal changes are studied by using a variety of remote sensing data, and by a modeling approach. This laboratory is also in charge of organizing interdisciplinary research and education programs in graduate school.	Yasushi YAMAGUCHI Masao TAKANO HIRANO Yasuhiro Takahiro Sasai
Geology and Geobiology	The basis of classical geology and paleontology is careful field work and sample collection. In our group we combine this tradition with use of modern analytical methods that enable us to determine the formation conditions, age and origin of a wide range of rocks as well as to carry out DNA analyses of fossil and living organisms. Through our research and graduate education programs, our group aims to further understanding of how a wide range of geological environments develop. The main research topics are: 1) metamorphism and tectonics of the crust and its interaction with the mantle including large-scale material cycling; 2) sedimentology and its relation to tectonics; 3) the interaction between organisms and their environment; 4) the evolution of life on the earth.

Geochemistry and Cosmochemistry	The research and education in our laboratory are aimed at grasping the planet earth as a natural material object and emphasizing its links both to human activity and other parts of the cosmos. To attempt to understand the dynamic and static processes of the earth, we employ a range of different chemical tracers including chemical elements and their compounds as well as stable and radiogenic isotopes. The present earth environment results from chemical processes over the past 4.6 billion years. Hence, to understand the present environment, it is important to trace the history of the chemical evolution of materials since the formation of the solar system. In our laboratory we combine "cosmochemistry" studying extraterrestrial materials such as meteorites, lunar samples etc. with "geochemistry" studying terrestrial materials and their interaction with human activity, and are actively engaged in research and education in the fields of "cosmochemistry," "geochemistry" and "environmental chemistry."

Earth and Planetary Physics	The relationship between humans and environments is fostered on the surface of 500 million km² of the Earth and as a result of the 4.5-billion-year history of the solar system. Our research group investigates spatio-temporal dynamics of this environmental background. Our research subjects include (1) theoretical studies about the formation of the solar and planetary system, (2) theoretical studies about the dynamics of Earth's interior as a multi-sphere interaction system, and (3) comprehensive studies about active crustal processes such as earthquakes and volcanoes.

Earth and Planetary Dynamics	The Japanese Islands are located in a subduction zone. Therefore, seismicity and volcanism are extremely active around Japan. Our research group conducts studies and education on seismology and volcanology on the basis of geophysical observations. Our major research subjects are: 1) development of a new observation system for crustal activities at the Nankai Trough, and 2) disaster prevention of seismic hazards due to great earthquakes. These studies are essential to the relationship between human life and natural phenomena.

Earth History Study	The earth today is a mirror that reflects both the results of events long ago and the possibilities of the future. Our research group explores the earth's varied 4,600 million year history. Encompassing both natural phenomena and human activity, we examine the history, chronology and significance of rocks, fossils, archaeological materials and cultural assets. Through the collection and analysis of samples in the field and in the laboratory, we can advance our knowledge of the complex world in which we live in.

Global Environmental Variation	ln order to clarify the processes of the global environmental variation, the dynamics of particulate, dissolved and gaseous materials in the atmosphere, hydrosphere and cryosphere are investigated physically and chemically through field observation and sampling in remote and urban areas in the Asia-West Pacific region.

Climate Science	Maintenance and variation of climate are determined by natural factors as well as by human activities. It is important to understand the tendency of climate change over a longer period, based on cumulative knowledge of phenomena in the atmosphere and hydrosphere over shorter periods. By advanced studies on the individual fields and synthesizing them, we must make efforts to predict possible climate changes over decades and centuries, or more.

Global Geochemistry	Biogeochemical cycles play important roles in maintenance and variation of the Earthls surface environment. Purpose of this research group is to make clear processes of biogeochemical cycles in atmosphere-hydrosphere-geosphere and their diversities of variation using chemical and isotopic tracers and their mathematical analysis.	Hiroshi MORIMOTO Hiroyuki KITAGAWA Urumu TSUNOGAI Osamu ABE Tamihito NISHIDA
Radiation and Life Sciences	All living things have been exposed to the natural radiation originating from radioactive materials existing in the ground and air since their birth. The humankind acquired artificial radiation at the end of the 19th century. Monitoring methods of both natural and artificial radiation are developed for the sake of radiation protection. The interrelationship between life and environment is analyzed by means of radiation. Our department implements education and research concerning these themes.	Michihiro SHIBATA Kazuhito TAKESHIMA
Global Water Cycle	Water is essential for life. It circulates on earth, and even a small fluctuation of the water cycle can cause serious problems on human life. The complex nature of the multi-scale temporal and spatial variability of the water cycles makes its understanding and prediction difficult. The global warming and adjunct environmental changes also became an urgent societal issue. The Hydrospheric Atmospheric Research Center (HyARC) of Nagoya University was established to be a national core research center to facilitate national and international interdisciplinary cooperative studies on the global water cycles in order to reveal the multi-scale structure of the water cycle and to understand its variability.
