Course overview and goals

This course is intended for undergraduate students who are interested in learning about Earth System Science. The course will cover the basic concept and goals of Earth System Science and the techniques used in Earth System Science. We will also explore the history of the Earth as an example of a habitable planet and will consider how the coupled evolution of Earth's environment and life can be understood in the framework of the biogeochemical cycles.

Course description and aims

Students will learn the following skills from taking this course:
・Be able to understand the basic concept and goals of Earth System Science
・Be able to recognize the sequence of and interrelationships between major events in the history of the Earth and life
・Be able to recognize the major techniques employed by theoretical studies of biogeochemical cycles
