13. Global warming caused by greenhouse gases is one of the most severe environmental problems in global change. The aim of this research is to clear the carbon cycle in ocean, which is a large reservoir of carbon and has an important role of climatic change. The flux and characteristcs of particulate materials sampled in a sediment trap and sea-bottom sediments sampled by a multiple corer are analyzed as a point of view of carbon cycle and carbon flux in ocean. Dissolution and decomposition of particulate materials duribg the transportation process and diagenesis at the sea-bottom interface are important processses of carbon cycle in the deeper part of the ocean. We have researched thse processes and we will make their model.

13. This study is planned as a five year project started from FY 1995 to elucidate the more appropriate arrangement of lands to be reclaimed in the bay together with the appropriate redistribution or reduction of existing effluent discharges into the bay by carrying out simulation experiments with hydraulic and numerical models as assessment tools. This study also aims to establish effective measures or technologies for the bay to compensate the unfavorable development impacts and to restore or enhance the environmental capacity of the bay itself based on the field survey for substance transport and assimilation processes in the bay and on the simulation experiments with hydraulic and numerical models for tidal flow control measures such as structure construction or topography modification on the bay bottom. The rational application of ecosystem model is the other task of this study to evaluate the ecological effects of these measures and to round off this study at its final stage.
