Class Objectives
/Class Outline The ocean cannot be ignored when understanding our planet, the Earth. To understand the ocean scientifically, it is necessary to understand the fundamental phenomena and events, and to grasp the outline of investigation techniques required for understanding them. The ocean floor records a history spanning 200 million years, and unraveling it allows us to understand the present while cultivating the ability to think about the rapidly changing modern world from an Earth science perspective.

Class Schedule Lecture 1: What is the “sea”? Introduction from its origins to its current state.
Lecture 2: Technology to investigate the Ocean-1 (Ship, ROV, AUV, HOV, direct method).
Lecture 3: Technology to investigate the Ocean - 2 (indirect method, elastic wave exploration, underwater communication).
Lecture 4: Undersea topography/geology (ocean ridges, trenches, TTT, plateaus, TF faults, active faults, formation of geological strata).
Lecture 5: Ocean dynamics, ocean circulation, sea level change.
Lecture 6: Accretionary complex - formation and growth of continents (Nankai Trough, IBM).
Lecture 7: Accretionary complex - Earthquakes and Tsunamis (Nankai Trough).
Lecture 8: Accretionary complex - Earthquakes and Tsunamis (Japan Trench).
Lecture 9: Submarine volcano (Hawaii, IBM, Kikai Caldera, Ontong Java Plateau).
Lecture 10: Origin of life, life in extreme environments, extraterrestrial life.
Lecture 11: Resources - Conventional (oil, gas), CCS, CCUS.
Lecture 12: Resources - Unconventional types (methane hydrate, manganese nodules, cobalt-rich crust, rare earth mud).
Lecture 13: Mankind's dream, sample return from the mantle.
Lecture 14: The Anthropocene, the relationship between humans and rapid changes in the global environment, can we cool down the boiling Earth? , Geo-Engineering? , summary.
Lecture 15: Open Seminar

Suggestions on
Preparation and
Review Lecture 1: Understand why the formation of the oceans led to the miraculous evolution of the Earth over its 4.6-billion-year history.
Lecture 2: Understand the equipment and direct methods for investigating the ocean.
Lecture 3: Understand the equipment and indirect methods for investigating the ocean.
Lecture 4: The topography and geology of the ocean floor are better preserved than those on land, so we will understand the history of various history from there.
Lecture 5: Understand that seawater circulates over time, transports materials and energy, and has various effects.
Lecture 6: Understand the structure of modern accretionary complexes and island arcs formed by plate subduction.
Lecture 7: Understand the relationship between the various types of earthquakes that occur in the Nankai Trough accretionary complex and geological structures.
Lecture 8: Understand the mechanism of the Tohoku Earthquake and Tsunami in 2011.
Lecture 9: Understand the types and scales of submarine volcanoes and their meanings.
Lecture 10: Understand the survival strategies of microorganisms that live in the extreme environments beneath the ocean floor.
Lecture 11: Understand the use of conventional resources and new science and technology toward carbon neutrality.
Lecture 12: Understand the use of non-conventional resources.
Lecture 13: Understand the current state of science and technology regarding sample returns from the mantle and discuss new ideas.
Lecture 14: Understand the "Anthropocene", which has been proposed as a new geological period classification. Discuss how humans relate to the earth.
Lecture 15: Open Seminar
