  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. The objectives of this project are to use artificial chemical substances, rare earth metals, heavy metals and lead isotopes as tracers to investigate the material cycle in the coastal environments and to develop analytical techniques and monitoring technique. Based on three-dimensional analysis of the tracers, the transition in the flow of substances into the marine environments in recent years and behavior in the environment will be elucidated.
