Outline of Annual Research Achievements

生物地球化学変数に関する地球システムモデル研究において、初となる複数モデルのLarge Ensemble 解析を、北太平洋を対象として行った。その結果、北太平洋の気候モデルは、全体として海洋の酸素減少トレンドを過小評価していること、また観測と同程度の酸素減少量が生じているモデルでもその現象はもともと過大評価されている溶存酸素濃度と関係しており、さらにいずれのアンサンブルも、観測された溶存酸素減少と水温上昇の関係をとらえていないことが明らかになった。これらの結果は、地球システムモデルが過去変動の再現性に問題があることを意味しており、またこのことはこれらのモデルによる将来予測の妥当性に疑問を投げかけるものである。北太平洋表層における栄養塩やクロロフィル、溶存炭素の経年変動を、海洋物質循環モデルの計算結果などを用いて、明らかにした。当該モデルおよび気候モデルで別に実施した超長期温暖化実験で得られた物理場を用いて、温暖化実験を実施した。その結果、水温上昇を含む物理プロセスは酸素の減少に最も効くが、難分解性溶存有機物を除く生物化学プロセスは酸素を増加させる傾向があった。しかし、難分解性溶存有機物は水温の上昇に伴い、バクテリアによる分解が進むため、時間スケールが長くなるほど酸素濃度減少に影響を与えることが明らかとなった。インド洋の塩分・酸素・栄養塩変化について解析をすすめ、観測でとらえられた変化がインド洋ダイポールと関係した一時的な亜表層酸素変化と結びつくことを明らかにし論文として発表した。塩分分布の細かな変化を起こす現象に注目した解析に協力するとともに、インド洋の塩分・酸素・栄養塩変化について解析をすすめた。日本海南部と東シナ海域における貧酸素化トレンドの解析結果を踏まえ、これらの海域の結節点である対馬海峡域に生息する魚類に将来貧酸素化の影響が現れる年を魚種別に予測した。
