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.

该奖项为怀俄明大学的水文物理实验室建立了一名技术人员。 该技术人员的目的是提供广泛的地球科学研究与定量地球物理测量之间的新联系，以实验了解地球过程，并协助培训学生和科学家。揭示有关近乎提交环境的属性和过程 - 在多个空间和/或时间维度中使用手动探针可以访问的深度和过程 - 对于促进环境地球科学的进步至关重要。水直生理包括从地球表面到与现代水文系统相关的最深地下水的深度的水文过程和异常的观察和测量。这套地球物理学方法涵盖了地球科学的大部分：冰川学，沉积学，水文学，生态学等。该奖项使全国各地的一系列科学家能够获取水文物理实验室和相关测量专业知识的资源。该项目的核心使命是在怀俄明大学提供实验性水域技术员，该技术人员为广泛的地球科学社区提供服务，以支持实验性水域研究。目标是：1）使广泛的科学家能够从水域测量中受益，2）提供仪器和方法培训，3）有助于方法论进步，以及4）增强外展活动。技术人员进行测量，并协助访客使用或设计实验设备，并进行样品制备。该技术人员专注于地面穿透雷达，电阻率和核磁地球物理方法。在实验室中，主要努力是为了支持实验研究和材料性质校准。实验性水域物理学工作还在实体实验室外进行，因此，技术人员还为相关的现场实验提供了支持，尤其是与获取样本和开发材料财产转换功能所需的样品和辅助测量有关。该奖项反映了NSF的法定任务，并通过评估智力效果来评估crotial and crarit和accrit和广泛的影响。
