  • Textbook

  • Seawater Travels Around, Heat Also Travels Around

  • Observation Vessels Travel Around, Ships Also Travel Around


    Hokkaido University has two training ships, the "Oshoro Maru" and the "Ushio Maru". In this lecture, you will learn about actual "oceanographic observation" and the hull structure of the "Oshoro Maru", which is designed for "safety".


    With the development of remote sensing (satellite and aircraft observation technology), it is now possible to obtain (observe) a variety of information without going to the field (ocean). Then, is it really no longer necessary to spend time (and money) in the dangerous oceans?

    The ocean is not only a field for learning about the global environment, but it is also a place of daily life, a trade route that connects the world, and a border that separates nations. What are the various forms (features), characteristics, and structures (performance) of the vessels that operate there?

  • Electromagnetic Waves Travel Around

    In "Electromagnetic Waves Travel Around" students learn about oceanographic observations using electromagnetic and sound waves.

    Electromagnetic waves and sound waves are the same "waves" and have the property of propagating through space, allowing information to be obtained remotely without having to contact the object.

    The aim of this course is to understand the information obtained by using these waves and their advantages and disadvantages.
