Outline of Annual Research Achievements

令和3年度は米国イェール大、仏ソルボンヌ大、独マックス・プランク研究所、タイ・マヒドン大をはじめ10カ国計30機関との間で国際共同研究を実施し、計10件の国際共著論文を出版した。マントル深部及び核の熱化学特性、始原物質の貯蔵機構、熱源元素総量などを軸として得られた成果を総括し、領域全体の国際活動の成果取りまとめを行った。前年度までと同様に地球惑星科学連合(JpGU)年次大会において国際セッションを主催し、本領域で得られた核－マントルの相互作用と共進化に関する研究成果を世界の研究者と共有するとともに、本領域の活動をさらに発展させるべく活発な議論を行った。
これらを通し、最終的には「核－マントルの相互作用と共進化」について領域として新たなモデルを提案し、新たな学理として統合的地球深部科学の確立を試みた。国際活動の成果取りまとめを計画的に進めるために、随時総括班メンバーによるメール会議を行った。その他、社会・国民に向けた研究成果情報の発信も精力的に実行した。具体的には、英文ホームページ及びSNSを活用して成果の周知及び情報発信を国内だけでなく国外に向けても行った。これらに加え、本領域の活動により得られた新たな知見を集約した英文書籍の編集作業が大詰めの段階となった（この英文書籍は、米国地球物理学連合から出版を予定している）。これらを通じ、本研究プロジェクトの成果を一般レベルから専門家レベルまで国内外を問わず幅広い対象に向けて発信した。
また、新型コロナウイルス感染症の蔓延により延期となっていた成果発表会をオンラインで開催し、海外からの参加者を含む約80名が参加した。この成果発表会では、領域の総括と共に新たな研究の展開についての発表も行われた。
