Outline of Research at the Start

日本の南～南東を流れる黒潮・黒潮続流の周辺海域では、冬季に深い鉛直対流が起こり、春以降大量の水が、水温・塩分などの気候変動シグナルや二酸化炭素などの物質とともに、海洋の表面から内部へと沈み込む。この沈み込んだ水「亜熱帯モード水」がその後どのように移動・変質し、さらにはどのように海面に再出現し、そこでの大気や化学生物環境にどのような影響を与えるのかを、自働観測ロボットや船舶を使った物理・化学観測により解明する。

Outline of Annual Research Achievements

約2年半にわたる酸素・pHセンサー付プロファイリング・フロートの観測を2023年9月に無事終え、12台により92～256（平均181）回の観測データを得た。フロートの酸素データについて、昨年度に開発したフロート投入時の船舶観測データを利用した品質管理手法に、フロート海面浮上時の大気中酸素濃度観測を用いた時間ドリフト補正を加え、初めてフロートに大規模搭載したRINKO酸素センサーの品質管理手法を確立した。この結果とともに、得られた水温・塩分・酸素・pHデータを用いて、亜熱帯モード水のAOUの分布と変動、北海道南東沖の2022年海洋熱波発生時の溶存酸素変化とメカニズム、大気海洋間酸素フラックスの定量、黒潮再循環域の亜表層における全炭酸と酸素の季節変化、といったテーマについて論文執筆を進めており、2025年刊行予定のJournal of Oceanography特集セッションでの一斉論文発表を予定している。
これと並行して、既存のデータの解析による研究を進めた。Kobashi et al. (2021, 2023)では、亜熱帯モード水の層厚変化がそれより浅い等密度面の深さを変化させ、海面水温ならびに海洋表層貯熱量を変化させるという「モード水の持ち上げ効果」を発見した。これは、海洋内部の変動が海面水温に影響する新たなメカニズムの発見である。Oka et al. (2023)ではさらに、本新学術領域研究を横断する海洋物理学の研究者と気象学の研究者の協働により、日本の南の亜熱帯モード水の厚さの十年規模変動が海洋表層貯熱量を通じて台風の強弱に影響することを示し、結果をScience Advances誌に発表した。現在、この効果が他のモード水についても見られること、またこの効果が海洋表層の生物生産にも影響を与えていることについて解析と論文執筆を進めている。
