项目摘要

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.

该 MRI 奖项将资助将美国自然历史博物馆（AMNH；纽约州纽约市）已有 21 多年历史的电子探针显微分析仪 (EPMA) 更换为最先进的新型仪器。 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，它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，并且对大多数分析都是无损的。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职人员、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研究提供了基础数据。高调的火山学科学研究；火成岩、变质岩和沉积岩岩石学，包括气候科学；矿石/资源地质；和材料科学。考虑到纽约地区依赖 EPMA 的地球科学研究人员密度很高，一台最先进的新仪器对于他们正在进行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、教育和公共推广活动，包括：(1) EPMA 培训和推广，面向 CUNY 校园中代表性不足的科学技术本科生，(2) 参加 AMNH 和 CU 的 REU 项目的本科生，(3) AMNH 收集材料的特征和实验生成的参考材料，与研究同事和公众共享，(4)每年有 500 万参观者参观博物馆关于地球和外星地球科学的公共展览，以及 (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 NSF 的法定使命和通过使用基金会的智力价值和更广泛的影响审查标准进行评估，该项目被认为值得支持。
