MRI-R2 Consortium: Development of a National Geoelectromagnetic Facility

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该MRI R2奖将为NSF提供为期24个月的资金，用于开发支持国家地电磁设施（NGF）的仪器。该设施将允许研究人员对地球进行成像。美国近地表，地壳和地幔的电性质的三维和高分辨率。岩石和矿物的电学性质是由岩浆和含水流体的存在和化学性质、总体化学和矿物组成、地层温度、氢和其他挥发物含量决定的。NGF将由27个创始成员机构和54个参与机构组成。该设施将纳入一个国家地电磁设备库。该设备将由俄勒冈州立大学和Zonge工程研究组织开发和制造，并由研究pi进行维护检查。这些仪器将是模块化和低功耗的。他们将能够测量在微赫兹到千赫兹范围内的地电磁变化，对自然和人工磁场进行成像。NGF仪器对于开辟新的研究途径和支持正在进行的水、矿物和碳氢化合物勘探、二氧化碳封存、水文和地热研究、地球微生物学、气候变化研究、污染物和水库监测、火山灾害研究和岩土技术研究至关重要。这一努力将建立一种目前在美国没有的能力。集合仪器模型将允许访问EM设备和数据产品。该仪器库将支持广泛的研究，包括地震学、冰川学、水文学、勘探、气候变化、灾害和地球微生物学。它将支持多个机构的众多调查人员。这样，相关的研究生和本科生将获得仪器使用和EM经验。现有的外展计划（应用地球物理经验之夏）将得到支持。新仪器的参考设计已经开发出来。在向社区发布采集协议后，将进行接口开发和进一步的基准测试。成功的测试和验证将导致设计周转和随后的商业合作伙伴生产。＊＊＊

Schultz0960342This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This MRI R2 award will provide NSF funding over 24 months to develop a instrumentation to support a National Geoelectromagnetic Facility (NGF). The facility will allow researchers to image Earth?s near-surface, crust and mantle electrical properties in three dimensions and at high-resolution. Rock and mineral electrical properties are defined by the presence and chemistry of magmatic and aqueous fluids, bulk chemical and mineral composition, formation temperature, and hydrogen and other volatiles content. The NGF will consist of 27 founding member institutions and 54 participating PIs. The facility will incorporate a national pool of geoelectromagnetic equipment. The equipment will be developed and fabricated by the OSU and the Zonge Engineering and Research Organization and maintained for checkout by research PIs. The instruments will be modular and low-power. They will be able to measure geoelectromagnetic variations over a micro-hertz to kilo-hertz range, imaging natural and artificial fields. NGF instruments will be critical for opening new research avenues and supporting ongoing studies in water, mineral and hydrocarbon exploration, CO2 sequestration, hydrologic and geothermal research, geomicrobiolgy, climate change studies, contaminant and reservoir monitoring, volcanic hazards studies, and geotechnics. This effort will establish a capability currently unavailable in the US. A pooled-instrument model will allow access to EM equipment and data products. The instrument pool will support a broad spectrum of research including seismology, glaciology, hydrology, exploration, climate change, hazards and geomicrobiology. It will support numerous investigators at multiple institutions. In so doing, associated graduate and undergraduate students will gain instrument access and EM experience. An existing outreach program (Summer of Applied Geophysical Experience) will be supported. A reference design for the new instrumentation has already been developed. Interface development and further benchmarking will ensue after release of the acquisition protocol to the community. Successful testing and validation will lead to design turnover and subsequent manufacture by the commercial partner. ***
