This award establishes a technician in the Hydrogeophysics Laboratory at the University of Wyoming. The purpose of this technician is to provide a novel link between broad Earth science research and quantitative geophysical measurement to understand Earth processes experimentally, and to assist in training students and scientists. Revealing properties and processes about the near-subsurface environment - deeper than can be accessed with manual probes, in multiple space and/or time dimensions - is important to promoting the progress of environmental geoscience. Hydrogeophysics encompasses the observation and measurement of hydrologic processes and anomalies from the Earth's surface to the depth of the deepest groundwater that is connected to modern hydrologic systems. Research enabled by this diverse set of geophysical methods spans much of Earth science: glaciology, sedimentology, hydrology, ecology, and others. This award enables a range of scientists across the country to access resources of the Hydrogeophysics Laboratory and related measurement expertise. The core mission of this project is to provide an experimental hydrogeophysical technician at the University of Wyoming who serves the broad geoscience community in support of experimental hydrogeophysical research. The objectives are to: 1) enable a broad range of scientists to benefit from hydrogeophysical measurements, 2) provide instrument and methodology training, 3) contribute to methodological advancements, and 4) enhance outreach. The technician performs measurements and assists visitors in using or designing experimental apparatus, and with sample preparation. The technician focuses on ground penetrating radar, electrical resistivity, and nuclear magnetic geophysical methods. In the lab, primary efforts are directed towards supporting experimental research and material property calibrations. Experimental hydrogeophysics work is also conducted outside the brick-and-mortar lab, and therefore the technician also provides support to related field experiments, particularly related to acquiring samples and ancillary measurements needed to develop material property transform functions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项在怀俄明州大学水文物理实验室设立了一名技术人员。 该技术员的目的是在广泛的地球科学研究和定量地球物理测量之间建立一种新的联系，以通过实验了解地球过程，并协助培训学生和科学家。揭示近地表环境的性质和过程--在多个空间和/或时间维度上，比手动探测更深--对于促进环境地球科学的进步非常重要。水文物理学包括观察和测量从地球表面到与现代水文系统有关的最深地下水深度的水文过程和异常。这种多样化的地球物理学方法使研究跨越了地球科学的大部分领域：冰川学、沉积学、水文学、生态学等。该奖项使全国各地的科学家能够获得水文物理实验室的资源和相关的测量专业知识。该项目的核心使命是为怀俄明州大学提供一名实验性水文地球物理技术人员，为广泛的地球科学界提供服务，支持实验性水文地球物理研究。其目标是：1）使广大科学家能够从水文地球物理测量中受益，2）提供仪器和方法培训，3）促进方法进步，4）加强外联。技术人员进行测量，并协助参观者使用或设计实验仪器，并与样品制备。该技术员主要研究探地雷达、电阻率和核磁地球物理方法。在实验室中，主要工作是支持实验研究和材料性能校准。实验水文物理学工作也在实体实验室之外进行，因此技术人员也为相关的现场实验提供支持，特别是与获取样品和开发材料属性转换功能所需的辅助测量有关的实验。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
