Outline of Annual Research Achievements

東南極氷床のうち海底に着底して温暖化に対して脆弱と考えられているウィルクスランドの氷床変動を復元するために、海洋コアを使った分析を進め、その結果について議論を行うべくアメリカスタンフォード大学のDunbar教授を訪問した。また同じく海底に着底してその将来の安定性が危惧されている西南極氷床の変動についても、アメリカのライス大学のAnderson教授を訪ね、ロス海などの堆積物試料を用いた共同研究の遂行について議論を行った。前者については学生の修士論文研究のテーマとして進め、成果の一部を国際誌に投稿するに至った。後者についてはすでに共同でアメリカ科学アカデミー紀要（PNAS)にて発表しているが、2018年11月からー2019年初旬にかけて再び西南極沖にサンプリングに出るということから、具体的な共同研究の方向性について打ち合わせを行った。一方、オーストラリア国立大学には複数回に渡って訪問し、グレートバリアリーフの試料を使った共同研究に関して、論文化の議論などを実施した。成果の一部は今年度にNatureとNature Geoscience誌を含む4篇以上の国際誌の論文として公表するに至った。また、オーストラリア国立大学訪問時に、シンポジウムでの招待講演や他大学でのセミナーを行い、様々な研究者と交流を進めることで、今後の氷床変動と気候変動についての共同研究について具体的な議論を行うことができた。キャンベラ大学のWhite准教授とは、研究代表者がライス大学と共同で発表した手法を、オーストラリアの研究機関が採取した海洋堆積物試料に適用し、氷床の変動についての情報のみならず、海洋循環などの複数現象の有無とその規模の復元が可能にし、その成果について国際誌に公表した。アメリカ地球物理連合においても招待講演で氷床変動と気候変動に関する研究成果の発表を行った。
