1. Survey of ocean areas for an ecological model
to improve the negative impact of adhering creatures |

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 |

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 |

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 |

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 |

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. |
6. The physics of sea that freezes and a biological
model |
3 |

S. Tabeta |
Practical use of prediction on the movement of sea ice to
protect the marine environment is investigated to construct model on the physical
behavior of ice sea and an ecological model. |
7. Developing a hybrid ocean environmental simulation |
3 |
3 |
S. Tabeta |
To analyze the interaction between large sea areas and local
sea areas, an ocean model combining a full 3D model and a static pressure model
is developed. |
8. Practical and applicable methods for a biome
with a climate gradient |

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 |

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 |

H. Kagemoto |
The generation mechanism of scum (suspended chemical organic
sludge) is clarified. |
