项目摘要
南極海沿岸の四割に及ぶ領域で南極底層水・沿岸陸棚水の特性変化の実態を把握し、あわせて酸素同位体比解析のための資料の収集とそれによる変動原因の考察を行った。南極底層水は全般的に低塩化しつつある。ロス海では特に顕著で、陸棚水の低塩化と関連している可能性があるが、酸素同位体比解析により氷床融解の影響が示唆された。酸素同位体比は底層水の生成源の推定にも有効であった。インド洋区における起源淡水として降雪と陸氷の分析を実施したところ、平均的には両者は十分区別可能で、本手法の有効性が示された。
A study on the characteristics of Antarctic bottom water and coastal shelf water in the Antarctic Sea coastal areas and their causes The Antarctic bottom water is completely low. The possibility of the degradation of the shelf water and the effect of the dissolution of the bed on the analysis of the isotope ratio of the acid is demonstrated. There is a possibility that acid isotope ratio may be used to estimate the source of bottom water. The analysis of the origin of fresh water and snow in the western region is very different from that of the average.
