1531313Parsekian Funding from this Major Research Instrumentation (MRI) Program grant will enable an early career investigator to acquire a wireline, borehole nuclear magnetic resonance (NMR) well logging tool to be used for investigations of subsurface hydrologic properties. NMR spectroscopy is sensitive to Hydrogen nuclei and has long been used for hydrocarbon exploration. The proposed NMR instrument is designed to fit into standard groundwater wells and is tuned to pick up the resonant frequencies specific to Hydrogen nuclei. The borehole NMR instrument would become part of the Facility for Imaging of the Near & Subsurface Environment (FINSE), an established Instrument facility at UW managed by trained staff and would support the field analytical capabilities of the Wyoming Center for Environmental Hydrology and Geophysics (WyCEHG), a center of excellence in hydro geophysics funded by NSF/EPSCoR. The NMR well logging tool will offer greatly improved spatial ( 0.5 m) and temporal resolution of subsurface hydrological parameters over conventional methods that typically aggregate subsurface hydrological observations over 10s of meters so the knowledge gained has the potential to be transformative and therefore supports NSF mission of promoting the progress of science.. The investigators intend to deploy the NMR tool for studies in vadose zone hydrology of interest to Critical Zone Observatories supported by NSF Division of Earth Sciences and studies of permafrost in the high Arctic; the instrument will be useful for groundwater resource assessment thus promoting the national welfare. The instrument will support hands on experiential learning by students using the NMR tool for studies of regional interest thereby fostering their future employability in fields that routinely engage in subsurface hydrologic studies, another aspect of the proposal that is congruent with NSFs mission of promoting the national welfare.***

1531313Parsekian 这项重大研究仪器 (MRI) 计划拨款将使早期职业调查员能够获得电缆、钻孔核磁共振 (NMR) 测井工具，用于调查地下水文特性。 核磁共振波谱对氢核敏感，长期以来一直用于碳氢化合物勘探。 拟议的核磁共振仪器设计用于安装标准地下水井，并经过调整以拾取氢原子核特有的共振频率。 钻孔核磁共振仪器将成为近地表和地下环境成像设施 (FINSE) 的一部分，FINSE 是威斯康星大学的一个已建立的仪器设施，由训练有素的工作人员管理，并将支持怀俄明州环境水文学和地球物理中心 (WyCEHG) 的现场分析能力），由 NSF/EPSCoR 资助的水文地球物理学卓越中心。 与通常汇总超过 10 米的地下水文观测数据的传统方法相比，NMR 测井工具将大大提高地下水文参数的空间（0.5 m）和时间分辨率，因此获得的知识有可能具有变革性，从而支持 NSF 的任务促进科学进步。研究人员打算部署 NMR 工具，用于 NSF 地球科学部支持的关键区域观测站感兴趣的包气带水文学研究以及高海拔永久冻土研究。北极；该工具将有助于地下水资源评估，从而促进国民福利。 该仪器将支持学生使用 NMR 工具进行体验式学习，进行感兴趣的区域研究，从而培养他们未来在经常从事地下水文研究的领域的就业能力，这是该提案的另一个方面，与 NSF 促进国家福利的使命相一致.***
