Outline of Final Research Achievements |
In this study, we succeeded in observing spatial and temporal distribution of dissolved gases in a deep hot-spring well using the passive diffusion sampler. Isotopic ratios of helium and carbon indicates dissolved gases have the magmatic component.

Academic Significance and Societal Importance of the Research Achievements |
本研究で採用した受動拡散サンプラーを用いた方法は、従来の試料採取とは異なり、採水の必要がないため他の場所からの汚染がなく、特殊な知識や器具が必要ないこと、分析においても溶存ガスを分離する手間がなく簡便であるため、地下水の溶存ガスを観測する上で多くの人の役に立つことが期待される。また温泉水の溶存ガスを時空間的に観測することで、地震や火山の活動を解明する手がかりとなる可能性があることを示すことができた。
