Outline of Annual Research Achievements

前年度までに採取したタスマン海の海水試料の分析法を開発したあと、順調に分析を進め南極海起源の中層水の循環経路の解明を行うことができた。これまで報告がない海域での鉛直プロファイルの復元ができたことで、海洋物理学的にも重要な知見を得ることができた。また、氷期から現在にかけてのグローバルな氷床量変動は、気候システム全体にとっての境界条件となるために重要な情報であるが、多くのサンゴ骨格の分析により、これまでにない精度での復元に成功するとともに、東オーストラリア海流の強弱と世界最大のサンゴ礁であるグレートバリアリーフの成長との関係についての知見も、温度情報の復元と合わせることで初めて明らかにでき、地球温暖化が進行している状況での今後のサンゴ礁の応答について、国際的にも重要な知見を得るに至った。大気と海洋の結合度を定量的に理解するためにはサンゴ骨格試料の分析が重要な役割を果たすが、炭酸カルシウムの殻を形成するプロセスについての生物学的および化学的なプロセスについて、重要な知見について、飼育実験やゲノム情報などと化学分析情報を総合的に検討することで、明らかにすることができ、古環境復元の定量化について高精度な情報を得るための研究成果となった。さらに海洋情報を復元する上で重要な炭酸塩殻を形成する有孔虫についても、酸性化における骨格の微量金属の分布について、飼育実験試料とレーザーアブレーションを用いた局所高精度分析を行うことで、初めて関係性について明らかにすることができた。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

海水分析に伴ってこれまで報告がなかった南半球の東オーストラリア海域の海洋循環についても明らかにすることができるなど、順調に進んでいると判断できるため。

Strategy for Future Research Activity

これまでに得られた分析結果、特に海水の分析結果については次年度に国際誌に投稿する。有孔虫や中緯度から低緯度の堆積物から得られた古環境情報についても結果が出つつあるため、随時論文化を進めるとともに、追加の年代分析などを行うことで解析精度を高める。
