Outline of Final Research Achievements

In this research, we applied the analyses of the distribution of submerged aquatic vegetarions (SAVs) using GCOM-C, which was applied only to the shallow basin (Lake Biwa south basin) in the previous research, to the deep basin (Lake Biwa North Basin), and developed an algorithm that can discriminate in all lakes. This algorithm was also applied to Lake Tahoe in North America. In addition, we created a discrimination algorithm using deep reinforcement learning for the soft coral, Dendronephthya gigantea, on the seafloor of Tanabe Bay, and conducted a discrimination experiment using underwater images. By determining the application limit of remote sensing technology in advance and adding underwater images, we proposed an integrated application method of aquatic vegetation classification and aquatic organism discrimination algorithm combining both images.

Academic Significance and Societal Importance of the Research Achievements

本研究においては、水中の実測においてのみ調査可能であった沈水植物SAVのバイオマスを気候変動観測衛星(GCOM-C)画像を用いて判別可能とし、従来の適用範囲を琵琶湖全湖に広げたことの意義は大きく、今後の湖や貯水池管理に資する。同時に、深層強化学習を用いた水中画像判別による水中生物の判別は、リモートセンシングの適用限界を超えた場所とスケールでの湖や貯水池における生物相モニタリングの新しい手法を示し、これらを統合することにより、淡水域や沿岸域でのモニタリング技術開発に大いに貢献できる可能性を秘めている。
