[AHW19-P01] On-site gas measurements to assess groundwater dynamics in hydrological and hydrogeological studies – potential and challenges
キーワード：miniRUEDI, trace gases, gas monitoring, gas screening
The miniRUEDI portable mass spectrometer system (Brennwald et al., 2016, 2020) has been shown to allow a reliable and robust manner for the continuous on-site monitoring of gases in environmental (e.g., Giroud et al., 2023) and engineered systems (e.g., Tomonaga et al., 2019, 2022).
Based on our long-term experience in using the miniRUEDI technology to realize gas monitoring strategies, we aim to stimulate a discussion on the potential of gas tracers within the context of hydrological and hydrogeological studies (e.g., Brennwald et al., 2022; Schilling et al., 2023).
