Our living earth nurtures oceans, continents and life. The earth’s diversity is formed by the intensive changes of the interfaces of the earth’s interior, such as boundaries between crust, mantle and core, and plates. In addition, various phenomena observed on the earth are interconnected one another, which include earthquake and volcanic events, mantle convection, plate motion, seismic activity, plate formation and movements from the magma activities, water and carbon cycles in the earth’s interior which form deposits and geothermal resources, and deep subsurface biosphere.
Understanding the unified system of the mother earth, ocean and life in its exact nature will lead to obtaining more reliable knowledge of the earth on what happened in the past, what is happening now, where human race originated from, and where evolution is heading.
With these purposes, we explore the deep earth. The earth’s interior has accumulated information on the earth, and also has some areas where the ongoing dynamic events can be observed with high accuracy. Working together with domestic and international scientists, we promote International Ocean Discovery Program which is led by Japan.
