Outline of Annual Research Achievements

1.領域内の相互啓発と情報共有：全計画研究班の研究が円滑に進むよう統括を行った。WEB中継会議システムを活用して全構成員間のより緊密な連携を図った。情報共有の為、ホームページの更なる充実化を図り、各班の班会議、議事録等を公開し、国内外でのセミナーや会議の情報等の最新データを随時掲載した。また、平成28年7月には全体会議を開催し、今後の課題について検討・確認を行った。平成29年3月には、これまでの研究成果を総括し、最終報告書をまとめるにあたって、まとめの方針の確認を行った。
2.情報発信：研究成果を広く国内外の学界に紹介する為、ホームページ（和英）での研究業績ページの充実を図った。ニュースレターを発行し（H28年度は2回刊行）、研究成果を分かりやすく解説した。また、国内外に向けた情報発信の為、European Geoscience Union（平成28年4月）・地球惑星科学連合（平成28年5月）でセッションを主催した。
3.研究支援活動：「データベースワーキンググループ」を統括し、事故発生以降の環境データ、モデリングデータ、分析データを使いやすい形で整理し、関係研究者に提供した。また「分析チーム」を統括し、分析がIAEAスタンダードになるようproficiency testの結果を反映させた。
4.公募:実施と研究支援：各計画研究の補完・推進を目的として採択した第ニ期公募案件について研究支援を行った。また、若手研究者育成について、各計画研究班を幹事とする若手育成プログラムを引き続き実施し、規定条件をクリアした若手研究者6名を表彰した。
