摘要:The concentration and carbon isotopic ratio (δ13C) of dissolved inorganic carbon (DIC) in natural waters is often altered by microbial activity, even over short durations, which can affect sample preservation. Hence, the influence of these biogenic processes should be limite...

摘要:Abstract(#br)Quasi-periodic sampling and analysis of spring water were conducted at nine sites to investigate the effects of the 2016 Kumamoto earthquake on the major chemical composition, including hydrogen, and oxygen stable isotopic ratios, of spring waters. Transient inc...
