Outline of Research at the Start

海洋の微量金属は,海洋生物の必須元素,海洋循環や人為汚染のトレーサー,古海洋研究のプロクシ(手がかり)として化学海洋学に欠かせないものとなった.本研究の目的は,多元素分析法と安定同位体比分析法を活用して,海水中微量金属の海盆規模,表層から底層までの三次元・時間変動をあきらかにし,化学海洋学の理解をさらに深めることである.おもな内容は以下のようである.(1)新規な微量金属分析法の開発,(2)太平洋,インド洋などにおける微量金属の濃度および安定同位体比の鉛直断面分布の解明,(3)海洋鉛直分布とエアロゾル,海洋堆積物との相互作用の解明.

Outline of Final Research Achievements

We have developed analytical methods for the determination of Zr, Hf, Nb, and Ta in seawater and for the isotope ratio analysis of Mo and W in sediments and seawater. We have revealed the sectional distributions of dissolved and labile particulate Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb in the North and South Pacific, East China Sea, Japan Sea, and Okhotsk Sea. We have determined the isotopic ratio of Ni, Cu, and Zn in water and particulate samples collected from the North Pacific, East China Sea, South China Sea, and Japan Sea, discussing the sources and cycling of these elements. We have determined the isotopic ratio of Mo and W in sediment cores collected from the Japan and Arabian Seas, reconstructing paleoceanographic environments. We have clarified the first vertical distribution of W isotopes in the open ocean. These results were published as 20 original papers.

Academic Significance and Societal Importance of the Research Achievements

海水中の微量元素は,海洋循環のトレーサー,海洋生物の微量栄養素として重要である.本研究は多元素分析および同位体比分析という新しい技術を導入し,海洋における多元素,多核種の分布をあきらかにしてきた.従来の海洋化学の教科書を書き換えるような成果が得られた.特に海盆規模の人為起源汚染,および陸上風化と海水中成分の相関は画期的発見である.しかし,残された課題も多く,本研究の一層の発展が望まれる.
