In 2005, our COE program has the following curriculums (courses) for graduate students:
| COE Special Colloquium (All the members of the COE program; 2 points) |
| This colloquium is designed to help students learn how to develop multi-disciplinary projects. Graduate students, mainly Research Assistants from this COE program, will present their own research and discuss it with all participants. |
| Biogeochemistry of Photosynthesis (Shigenori Maruyama and Hiroyuki Ohta, 1 point) |
| Emergence and evolution of the photosynthetic organisms are important for the composition of the Earth's ocean and atmosphere, which are responsible for the development of multicellular organisms. This lecture will review the geological record of photosynthetic organisms, including some new topics in this research field. The lecture will also explain the biochemistry of photosynthesis. |
| History of Life and Life Under Extreme Environments (Shigenori Maruyama and Shiro Koshima, 1 point) |
| This lecture will cover the geological record of biological activity and the link between ancient and modern ecosystems. Modern ecosystems are a product of biological evolution over time. After the origin of life, most likely in deep sea hydrothermal systems, a variety of new ecosystems have developed in various local environments on Earth. Examining life under extreme environments may provide a window into understanding biological evolution in the past. |
| Chemistry of Earth's Oxidized Atmosphere (Shigenori Maruyama, Naohiro Yoshida, and Kazuhiko Shibuya; 1 point) |
| Photosynthetic activity is responsible for the development of the O2-rich atmosphere on Earth. This O2-bearing atmosphere produces ozone, which acts as a shield in protecting Earth's life from dangerous UV radiation. This lecture will explain the physics, chemistry, and biological interactions between Earth's atmosphere (troposphere and stratosphere) in the context of material circulation. Particular emphasis will be placed on explaining the physical processes of photochemical reactions and the stable isotope chemistry of the atmosphere. |
