This MRI award will fund the replacement of the 21+ year-old electron probe microanalyzer (EPMA) at the American Museum of Natural History (AMNH; New York City, NY) with a new, state-of-the-art instrument. The EPMA is probably the most important instrument for geochemical analysis of rock samples and experimental samples, providing unmatched capabilities for most elements at high precision, high-spatial resolution, and is nondestructive for most analyses. The current system serves many faculty, postdoctoral researchers, graduate and undergraduate students at AMNH, Columbia University (CU), institutions of the City University of New York (CUNY) and other regional institutions.Electron probe analyses provide fundamental data for a wide spectrum of high-profile scientific research on volcanology; igneous, metamorphic, and sedimentary petrology, including climate science; ore/resource geology; and material science. Considering the high density of geoscience researchers in the New York City area who depend on EPMA, a new state-of- the-art instrument is vital for the success of their ongoing and future research projects. The new EPMA will impact the multi-faceted research, education, and public-outreach activities of the primary users at AMNH, CU and CUNY including: (1) EPMA training and outreach to under-represented undergraduates in science and technology at the CUNY campuses, (2) undergraduates participating in REU programs at AMNH and CU, (3) characterization of AMNH collection materials and experimentally generated reference materials which are shared with research colleagues and the general public, (4) the 5 million annual visitors to the Museum's public exhibitions on Earth and extraterrestrial geoscience, and (5) numerous science education programs at the Museum that connect the public and K-12 students and teachers with active scientific research programs.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.

这项核磁共振奖将资助美国自然历史博物馆（AMNH; New York City， NY）用一种新的、最先进的仪器替换已有21年历史的电子探针微量分析仪（EPMA）。EPMA可能是岩石样品和实验样品地球化学分析中最重要的仪器，为大多数元素提供了无与伦比的高精度、高空间分辨率的能力，并且对大多数分析是非破坏性的。目前的系统为AMNH、哥伦比亚大学（CU）、纽约城市大学（CUNY）和其他地区机构的许多教师、博士后研究人员、研究生和本科生提供服务。电子探针分析为广泛的高水平火山学科学研究提供了基础数据；火成岩、变质岩和沉积岩石学，包括气候科学；矿石/资源地质学;还有材料科学。考虑到纽约市地区高密度的地球科学研究人员依赖于EPMA，一个新的最先进的仪器对于他们正在进行的和未来的研究项目的成功至关重要。新的EPMA将影响AMNH、CU和CUNY主要用户的多方面研究、教育和公共宣传活动，包括：(1)对纽约市立大学校园中未被充分代表的科学和技术本科生进行EPMA培训和推广；(2)参加美国国立自然科学研究所和科罗拉多大学REU项目的本科生；(3)对美国国立自然科学研究所收集的材料和实验生成的参考材料进行表征，并与研究同事和公众共享；(4)每年500万人次参观博物馆的地球和地外地球科学公共展览；(5)博物馆的众多科学教育项目，将公众和K-12学生和教师与活跃的科学研究项目联系起来。该奖项反映了美国国家科学基金会的法定使命，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。
