Humio Mitsudera 研究室（北海道大学）

AI 要約（直近 5 年の研究成果）

本研究室は、海洋の大規模な流れと水の物理的性質の変動メカニズムを明らかにする研究に取り組んでいます。特に、南極周辺の大洋循環、北太平洋の亜寒帯域、オホーツク海といった広域海域を対象として、風、海底地形、潮汐、密度成層などの要因がいかに流れや水温・塩分の分布を制御するかを調査しています。研究の手法としては、高精度の海洋数値シミュレーションモデルと衛星観測・現地観測データを組み合わせるアプローチを採用しています。渦や内部波といった小規模な流れの効果、複数の海域を結ぶ海水輸送、さらには気象条件や陸域からの淡水流入との相互作用まで、様々なスケールの現象を統合的に扱っています。主要な発見としては、従来の理論では説明できない上昇流・下降流のメカニズムの解明、海氷変動が広大な領域の海洋や大気に波及する影響の量的評価、潮汐が深層海流の経路や海域間の水交換を左右することなどが挙げられます。これらの知見は、北太平洋の栄養循環や気候変動への海洋の応答を理解するうえで重要な役割を果たしています。
