The major goal of my research is to contribute to the development of environmental technologies and ecosystem conservation through interdisciplinary and issue-oriented approaches. I have been conducting two studies mainly for developing marine environmental technologies and conserving coastal ecosystems focused on the linkage between forest, river and sea. At first, a seaweed bed restoration method using iron fertilizer has been developed. The lack of iron in coastal area was focused as a factor for depleting seaweed beds, so-called “barren ground.” The effectiveness of this method was confirmed as results of fundamental studies and a field test in Hokkaido. Meanwhile, I have evaluated material dynamics, such as iron, nitrogen and phosphorus, in the coastal areas and river basins for understanding the forest-river-sea linkage. I have focused on the influence of land use on estuarine environments in recent years.
In addition, I have engaged in interdisciplinary education in environmental and ocean related fields for developing human resources. I have been in charge of domestic and overseas internship programs in recent years. Graduate students have been sent to the international organizations in the overseas internship program. I evaluated educational effects of domestic and overseas internships on establishment of students’ career paths.
Study example for understanding the forest-river-sea linkage
- Influence of rice paddy fields on iron dynamics in rivers and the structural features of humic acids in their sediments of the northwest of Hokkaido, Japan
- Potential influence of oceanic environmental change on seaweed bed distribution in Tsushima Islands
- Influence of freshwater from terrestrial sources on iron concentrations in Kesennuma Bay, Japan
- Dynamics of iron in the Chikugo River Basin
- Changes in the coastal environment in Kamaishi Bay after the Great East Japan Earthquake
- Educational effect of internship for human resource development
