项目摘要

This project transforms an established, state-of-the-art, high-throughput, geologic dating laboratory at the University of Vermont into a national facility open for use by the broader science community. It will provide both intellectual resources and a venue for consistent, reliable, high-quality, and safety-focused preparation of samples using a hands-on model that integrates research and research training. Over the past several decades, the use of these nuclides in Earth Science has increased rapidly; however, sample preparation remains tedious, difficult, and hazardous, requiring strong acids and complicated and expensive clean laboratory facilities and expertise that are not readily available. The approach of this facility is cost-effective because it relies on existing physical and intellectual infrastructure and builds on demonstrated research and research training successes. Working closely with experts, the facility staff will broaden participation and build long-term relationships by proactively engaging students, faculty, and administrators at both undergraduate institutions and graduate institutions serving communities underrepresented in STEM. The facility will use collaborative outreach activities including campus visits and a seed grant program to bring minority students and their faculty mentors to the laboratoryThis is a new approach aimed at broadening participation in the rapidly expanding field of cosmogenic isotope geoscience by opening a successful cosmogenic geochemistry laboratory to the broader community. Building upon tested sample-processing and training protocols, we will facilitate research and research training by increasing access to 10Be and 26Al sample preparation. Because of limited laboratory availability, the cosmogenic nuclide community has remained small. Providing a national sample preparation facility will catalyze the inclusion of new and different scientists, increasing the number and diversity of projects involving these isotopes - a catalyst for transformative research. Supporting a community facility for sample processing and research training has numerous different broader impacts. 1) It directly addresses a current bottleneck in cosmogenic nuclide studies: the extraction of 10Be and 26Al from rock, soil, and sediment that precedes isotopic measurement. 2) It broadens participation by providing open access to a state-of-the-art processing facility for the many students and faculty who do not have such a facility at their home institutions. 3) The outreach program, supported by the experience of Semken and Whittaker, goes directly to faculty and students at institutions serving minority communities and the seed grant program brings faculty/student teams from Historically Black Colleges and Universities as well as Tribal Colleges to the laboratory for meaningful collaboration and hands-on training. 4) Technician support will provide for research training in isotopic clean lab methods for students, researchers, faculty, and young investigators in a variety of geoscience disciplines through lab residencies, lab consultancies, a yearly training course for those wishing to adopt these methods or start a similar laboratory.

该项目将佛蒙特大学现有的、最先进的、高通量的地质测年实验室转变为一个可供更广泛的科学界使用的国家设施。它将提供智力资源和场所，使用整合研究和研究培训的实践模型来一致、可靠、高质量和以安全为重点的样品制备。在过去的几十年里，这些核素在地球科学中的使用迅速增加。然而，样品制备仍然繁琐、困难且危险，需要强酸和复杂且昂贵的清洁实验室设施以及不易获得的专业知识。该设施的方法具有成本效益，因为它依赖于现有的物理和智力基础设施，并建立在已证明的研究和研究培训成功的基础上。该设施的工作人员将与专家密切合作，通过积极吸引本科院校和研究生院校的学生、教师和管理人员，为 STEM 中代表性不足的社区提供服务，扩大参与范围并建立长期关系。该设施将利用合作外展活动，包括校园访问和种子资助计划，将少数族裔学生及其教师导师带到实验室。这是一种新方法，旨在通过开设一个成功的宇宙成因地球化学实验室来扩大对快速扩展的宇宙成因同位素地球科学领域的参与。到更广泛的社区。基于经过测试的样品处理和培训协议，我们将通过增加 10Be 和 26Al 样品制备的机会来促进研究和研究培训。由于实验室可用性有限，宇宙成因核素群落仍然很小。提供国家样品制备设施将促进新的和不同的科学家的加入，增加涉及这些同位素的项目的数量和多样性——这是变革性研究的催化剂。支持社区设施进行样本处理和研究培训会产生许多不同的更广泛的影响。 1) 它直接解决了当前宇宙成因核素研究的瓶颈：在同位素测量之前从岩石、土壤和沉积物中提取 10Be 和 26Al。 2) 它通过为许多在其所在机构没有此类设施的学生和教师提供使用最先进的处理设施的开放机会来扩大参与范围。 3) 外展计划在塞姆肯和惠特克的经验支持下，直接面向为少数族裔社区服务的机构的教职员工和学生，而种子资助计划将来自历史悠久的黑人学院和大学以及部落学院的教职员工/学生团队带到实验室进行有意义的协作和实践培训。 4) 技术人员支持将通过实验室驻场、实验室咨询以及为那些希望采用这些方法或开始研究的人员提供的年度培训课程，为各种地球科学学科的学生、研究人员、教师和年轻研究人员提供同位素清洁实验室方法的研究培训类似的实验室。
