[SCG55-01] The Earth recycle and verification of ocean extinction hypothesis - New development in ocean plate research
★Invited Papers
Keywords:Earth, recycle, ocean distinction hypothesis, oceanic plate, inundation
Planet Earth is the only planet in the solar system where the warm surface environment and oceans that harbor life are stabilized by the long-term circulation (global recycling) of various materials such as rocks, water, and organic matter over tens of millions of years. However, 4.6 billion years after its birth, the Earth is now at a major turning point in global recycling, and the hypothesis of the complete disappearance of the oceans as early as 100 million years has been predicted as a possible future scenario. The key to this future is the infiltration of seawater into the oceanic plates. In this research area, we focus on the hydrophilic properties and inundation processes of oceanic plates, which play a major role in global recycling, and conduct comprehensive research to verify and clarify the oceanic extinction hypothesis on multiple scales. The objectives of this research area are (1) to elucidate the effects of inundation of the oceanic plate on global recycling, especially on the Earth's surface environment and life on Earth, and (2) to test the ocean extinction hypothesis triggered by increased inundation of the oceanic plate and water transport to the Earth's depths. This research area is a fundamental study of natural science that will create a new dynamic model of global recycling by reviewing the oceanic plate from multiple perspectives. The new vision of the future of the Earth, including the oceanic annihilation hypothesis, will bring about new changes and turning points in the field of earth and planetary science, including the redefinition of the discipline responsible for the future of humanity.
