We are conducting comprehensive education and research across the fields of physics, chemistry, biology, and geology, targeting the space that extends from the sea to the seabed, the seabed, and even the crust.In addition, regular long-term observations of the ocean at various spatial scales, from inner bays and coastal areas to offshore and open ocean areas, as well as from the red tract to the north and south polar regions, will reveal the structure of the ocean itself. We are also working to understand the structure and function of marine ecosystems, establish technology to predict their changes, and elucidate the mechanisms of climate change.As a result of these efforts, we will be able to acquire essential knowledge and technology for the smart and sustainable use of marine biological and inanimate resources.Furthermore, we are promoting education, research, and technological development related to the use of renewable energy obtained from the ocean.Activities in these diverse fields range from microscopic observations under a microscope to macroscopic (global) scale investigations across the globe.In terms of time, it encompasses ephemeral phenomena of a few seconds, minutes, and hours to long geological chronological phenomena of billions of years.All of these are positioned as activities aimed at achieving the SDGs.
