13 The purpose of this project is to establish advanced techniques for analysis 
   and evaluation of toxic substances in polluted soils.  The degree of the 
   effect of toxic elements depends on the chemical species, therefore, and 
   accurate and sensitive speciation analysis of toxic elements is much 
   important.

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 Deep aquifers(deeper than 800 meters below the groundwater surface) can 
   store large amount of carbon dioxide as aqueous solution under high formation 
   pressure. To evaluate the stability of the aquifer disposal of carbon dioxide,
   a natural-analogue study will be carried out on carbon dioxide behavior and 
   CO2-fixation mechanism in deep aquifers and adjacent strata.

13 Estuaries and enclosed bays are under increasing pressure of eutrophication 
   as a result of increasing by products of inland human activities.  The aim 
   of this project is to develop restoration methodologies which utilise the 
   food-webs in aquatic ecosystems including shells, fishes and birds.  
   This project is consisted of various interdisciplinary topics such as habitat 
   structure, ecological function,   sediment processes, nutrient dynamics and 
   physical restoration techniques.
