Research Abstract

海洋研究開発機構 海洋地球研究船「みらい」が2003年から2004年に実施した南太平洋を含む世界一周航海ですでに得られたデータを組み込んだ、海洋のマルチトレーサーデータベースを完成させることができた。放射性セシウムの新しいソースタームと解像度を上げた海洋大循環モデルによる再現計算を行った。データベースを利用して解析したところ、^<239,240>Pu/^<137>Cs 比が、表層から水深約1000mまで指数関数的に増加していることを見出した。世界で始めて、南太平洋、南大西洋およびインド洋の薄明領域(水深100m-1000m)の粒子状配位子の分布を求めることができた。
