Current Research Interests

To clarify the origins of materials in the earth's surface, their distributions and circulation mechanisms, and the links with global environment change, by using trace element concentrations and isotopic composition:

1. Geochemistry of submarine groundwater discharge and its impact on the costal marine environment;
2. Oceanic circulation and variation related to global climate changes:
   
   1. Water structure, the abyssal circulation and fluctuation of the Japan Sea, and
   2. Riverine fresh water fluxes from the North American continent into the Arctic Ocean.
3. The monitoring of formation mechanisms of chemical synthesis communities, such as bacterial-mats and methane fluxes in cold seep areas;
4. The phytoplankton distribution and its variation linked with marine environment changes:
   1. Emiliania huxleyi boom mechanism in the southeastern Bering Sea shelf, and
   2. Phytoplankton distributions in the North Pacific sub-arctic region and their seasonal variation;
5. The origins and long term transposition of anthropogenic material, and its impact on the marginal seas and North Pacific ecosystem:
   1. Aerosol chemistry and supply of continental origin nutrients into the North Pacific Ocean, and
   2. Sequence observation of air pollution material and transport in East Asia and their environmental impact assessment.
