This award will provide funds to acquire a bench-top scanning electron microscope (SEM) system and upgrade an aging laser ablation (LA) system that is paired with an existing inductively-coupled plasma mass spectrometer, both of which enable analysis and imaging of microscopic geological samples, including microfossils, volcanic fragments, and natural and synthetic glasses, rocks, and minerals. The two requested instruments, which may work in tandem or independently in the laboratory, will vastly enhance and complement the established research capabilities at the University of Rhode Island. Each of the principal investigators has a robust research program that will see immediate benefit to NSF research projects within the Geosciences. These instruments will contribute to the professional development of numerous undergraduate and graduate students, support the growing research program of an early-career scientist, and enable a broader platform of collaboration among Earth scientists across many disciplines among Rhode Island institutions.Upgrade of the LA system maintains and improves functionality of an established and productive laboratory, whereas acquisition of a compact SEM system adds new imaging capabilities in addition to enhancing and informing the use of the LA system. Measurements and images enabled by these instruments positively impact the PIs' endeavors to address key hypotheses across a range of Earth science fields, including (1) the role of volatiles and trace elements in plate tectonic cycles, (2) fragmentation processes during explosive and effusive submarine volcanism, (3) the mechanisms by which Earth's interior produces a diversity of magma compositions, and (4) the roles of preservation, taxonomy, and inherent chemical heterogeneity in microfossil records of past climate conditions.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.

该奖项将提供资金，以获取基准扫描电子显微镜（SEM）系统并升级与现有的电感耦合等离子体质谱仪配对的老化激光消融系统（LA）系统，其中启用了显微镜样品的分析和图像，包括微型地质学样本，包括微型材料，包括微型和自然片和天然化的镜子，以及玻璃，玻璃，玻璃，玻璃，玻璃，玻璃，玻璃。这两种要求在实验室中或独立起作用的仪器将大大增强和补充罗德岛大学既定的研究能力。每个主要研究人员都有一个强大的研究计划，该计划将为地球科学内的NSF研究项目带来直接的好处。 这些乐器将有助于众多本科生和研究生的专业发展，支持不断增长的早期职业科学家的研究计划，并为罗德岛州机构中许多学科的地球科学家之间在地球科学家之间提供更广泛的协作平台。洛杉矶系统。 Measurements and images enabled by these instruments positively impact the PIs' endeavors to address key hypotheses across a range of Earth science fields, including (1) the role of volatiles and trace elements in plate tectonic cycles, (2) fragmentation processes during explosive and effusive submarine volcanism, (3) the mechanisms by which Earth's interior produces a diversity of magma compositions, and (4) the roles of过去气候条件的微化石记录中的保存，分类学和固有的化学异质性。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
