The drastic change of air environment surrounding us is of increasing concern. We study how to solve this problem. Especially, we study the changing climate in eastern Asia including Japan.

Microparticles (aerosol particles) in the air influence local and global climate by scattering light or generate clouds. They are closely connected with air pollution such as acid rain and pollution disease. Our laboratory examines the behavior of aerosol particles using particle analysis techniques like electron microscope and others, and clarifies how those particles are generated and how they influence the surrounding environment.

We research volcano and granite in the field, and do chemical analysis using various equipment. This helps us to understand the development of magma, its differentiation, process of eructation and its characteristics.

The earth has experienced continuing evolution since the beginning and it has brought the results of variation. Various phenomena have occurred on the Earth and continue to occur. But mankind has not understood all of phenomena yet. This course looks at crust, mantle, behaviors and compositions of materials which constitute planets and how they are formed.

This course examines Earth's history, crustal change, land movement using the Earth's magnetic field. We also attend the moon exploration satellite planning initiated by Japan and research team of planetary magnetism using Mercury exploration satellite.

This course promotes the research of process implicated in water circulation on Earth from physical and chemical viewpoints. We learn about water circulation processes such as invisible precipitation, river water, groundwater and rhizic water by estimating and using various ion's 放射性 and stable isotope.

We study the influence of people's lives around sea area. It is necessary to clarify the mechanism of environmental variation after 12 century so as to try and improve the marine environment. Thus we research the environmental vicissitudes recorded on current living objects, fossil and deposition substances.

It is possible to recreate the environment when the old living objects were alive based on the research of biogenous sediments including coral. We can examine the supracrustal environmental variation and study the variations in time and distribution of deposition substance, and these will be used for future predictions of global warming.

This course examines the appearance and living style of extinct species from various fossils found in the geological layer. And we try to clarify the evolution of organisms and fluctuations in the Earth environment by recreating the environment when the organisms were alive.
