Outline of Final Research Achievements |
We aimed to develop a parameterization of pH (pH = f (salinity, oxygen, chlorophyll-a, etc.)) that can be applied to the Japanese coastal regions to predict the temporal and spatial changes and magnitude of ocean acidification in the coastal waters of Japan. Since a large amount of pH data is required to understand the dynamics of ocean acidification in coastal waters with large environmental variability, we improved the surface seawater monitoring system equipped with the Oshoro Maru of Hokkaido University, which makes several cruises per year to the Japanese coastal regions (off the coast of Hokkaido and Tohoku), to enable continuous multi-item data acquisition. The system has been improved to enable continuous data acquisition of multiple items.

Academic Significance and Societal Importance of the Research Achievements |
本研究による時空間的に詳細な日本沿岸海域におけるpHマッピングのための高確度なパラメタリゼーション技術は日本沿岸海域だけではなく、その他の沿岸海域においても海洋酸性化の実態解明へと展開でき、海洋酸性化の沿岸有用海洋生物への影響予測が可能となる。これは、世界的な海洋環境保全あるいは水産資源の持続に対する海洋酸性化対策を打ち出すことを導くことから、社会的貢献度が非常に高い。
