1. Survey of ocean areas for an ecological model to improve the negative impact of adhering creatures 3 3 M. Fujino S. Tabeta T. Katoh Adhering creatures negatively influence seawater quality. This problem can to be solved by large floating installs in the sea. The survey accurately predicts the biological behavior of adhering creatures and establishes a mathematical mode.
2. Survey and construction of an algae growth model 1 1 M. Fujino S. Tabeta T. Katoh Algae are expected to be a reliable means of purifying seawater in coastal areas. Algae is used as an example and its growth observed in Kurihama bay. After the observation, its growth model is discussed.
3. Constructing the MEC model on environmental assessment in coastal areas 3 3 M. Fujino S. Tabeta T. Kinoshita To restore the coastal environment in closed bays, an assessment study will conduct an experiment using a density flow diffusion model; conventional models do not represent real seawater flow. An MEC model representing correct local flow is constructed.
4. Constructing an evaluation method combining physical and biological processes, considering the characteristics of sea that freezes 5 3 M. Fujino S. Tabeta Y. Nishi The Sea of Okhotsk is a supply site of fishery resources and is now being focused on as a petroleum and natural gas resource. A feature of this sea area is sea ice in winter. This study develops an assessment model as a tool that combines processes in ocean physics and sea creatures.
5. Predicting and assessing the sea environment around the floating parking area in Yokosuka Bay 10 1 M. Fujino S. Tabeta D. Kitazawa T. Katoh This project applies a component of the IT mega float to a parking space in Yokosuka City. The research predicts and assesses environmental effect on the sea area by monitoring and through a biological model.

8. Practical and applicable methods for a biome with a climate gradient 3 2 H. Kagemoto This project constructs a biome with an environmental gradient that is a chamber to be constructed at the New Kashiwa campus of the University of Tokyo. The chamber is 200 m long, 50 m wide and 50 m high with a gradient in climate from tropical to frigid zones. The research constructs the biome in practice and investigates the effects of global environmental change on the ecological system.
9. Chemical compounds and their mechanism in forming generated by abrasion and compression of plastic materials 2 2 H. Kagemoto Chemical compounds generated during a treatment process of waste plastics at disposal factories are a cause of Suginami Syndrome. The research identifies chemical compounds formed and clarifies the mechanism of their formation.
10. Mass transfer simulation and quality improvement of the water in Tegamuma 2 2 H. Kagemoto The quality of water in Tegamuma Marsh was the worst in Japan in 27 years. Improving the marsh quality is investigated by numerical simulation of mass transfer phenomena.
11. The practical potential of floating wind farms 3 2 H. Kagemoto Wind electricity generation farms with mega-floats installed is discussed, focusing on the cost of electricity and on engineering methods of reducing the cost of construction.
12. The generation mechanism of scum at River Kandagawa 3 3 H. Kagemoto The generation mechanism of scum (suspended chemical organic sludge) is clarified.

1. Assessment of the effect of ships on the global environment 8 5 T. Ura Large ships propelled by diesel engines exhaust a lot of nitrogen oxide that considerably effects the global environment. To assess the environmental problem correctly, the LCA (Life Cycle Assessment) technique for ships is investigated.
2. Computational structural mechanics 10 3 Y. Toi Basic analytical and experimental research on structural strength is conducted aiming to quantitatively evaluate strength when a ship or an ocean platform is damaged due to collision or stranding. The research places special importance on developing an adaptive finite element method for a structural element and a complex structure.
3. Improving the performance of small boats 15 10 K. Kinoshita Improving total performance including racing of sailing boats and racing boats is investigated.

Asada Research on observing diastrophism on the sea bottom at a 1,000-m depth is conducted by a multi-beam depth sounder that applies kinematic GPS that can measure the movement of a ship with centimeter scale accuracy.

Asada Diastrophism is observed to monitor the sea bottom of Kumano trough and off Sanriku at a 3,000-m depth using a newly developed precise sounder system. It can measure the movement of a ship as precisely as a centimeter scale by combining a sounder and long distance kinematic GPS. Longterm reference data from the sounders between the sea bottom and on land will produce signals showing the movement vector of the earth's crust.
