MRI: Acquisition of hydrogeophysical downhole nuclear magnetic resonance instrument to support research and student training

1531313 Parsekian从这个主要的研究仪器（MRI）计划补助金的资金将使早期的职业调查人员获得电缆，钻孔核磁共振（NMR）测井工具用于地下水文特性的调查。 核磁共振光谱对氢核敏感，长期以来一直用于碳氢化合物勘探。 所提出的NMR仪器被设计成适合标准地下水威尔斯井，并被调谐以拾取氢核特有的共振频率。 钻孔核磁共振仪器将成为近地表环境成像设施（FINSE）的一部分，FINSE是华盛顿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和地球物理中心（WyCEHG）的现场分析能力，该中心是NSF/EPSCoR资助的水文地球物理学卓越中心。 NMR测井工具将大大提高地下水文参数的空间（0.5米）和时间分辨率，而传统方法通常将地下水文观测结果汇总在10米以上，因此所获得的知识具有变革的潜力，因此支持NSF促进科学进步的使命。 研究人员打算部署核磁共振工具，用于研究由NSF地球科学部支持的临界区观测站感兴趣的包气带水文学，以及北极高纬度地区的永久冻土研究;该仪器将有助于地下水资源评估，从而促进国家福利。 该仪器将支持学生使用NMR工具进行区域兴趣研究的体验式学习，从而促进他们未来在经常从事地下水文研究的领域的就业能力，这是与NSF促进国家福利的使命一致的提案的另一个方面。

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.***
