This award provides funding for the acquisition of a new Multi-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) instrument to support cutting-edge research in the earth and environmental sciences at Oregon State University (OSU). The acquisition of a latest generation MC-ICP-MS will have an immediate broad impact on the research of faculty at OSU and in the Pacific Northwest. Supported research activities have strong societal implications for the residents of the Pacific Northwest and elsewhere including studies of climate change, critical zone processes, anthropogenic pollution, natural hazards, and fisheries management. The acquisition will improve the ability of the College of Earth, Ocean, and Atmospheric Sciences and the College of Agricultural Sciences (OSU) to produce highly skilled graduates prepared for careers in a range of settings. Undergraduate and graduate education and research will be supported through facility tours and instrument demonstrations, class projects, student research projects, and course exercises.The analytical capability enabled by the new MC-ICP-MS will position OSU to remain at the forefront of rapidly developing high impact research areas. In just the past 5 years, analytical improvements in the design of mass spectrometers continue to push the boundaries of precision and accuracy at higher and higher sensitivities. These improvements will open up many new avenues of research by reducing the amount of sample material needed, improving the sampling resolution for all applications, removing interferences, and through the simultaneous collection of a larger number of isotopes. Specific examples of projects imminently proposed that will be supported by the MC-ICP-MS include: developing heavy stable isotopes as tools in environmental applications (e.g., detecting and quantifying uranium removal from contaminated groundwater; tracing non-ferrous metal smelting emissions); understanding critical zone processes (including tracing sources of soil inputs and examining the relationship between climate, erosion, and weathering); laser ablation measurements of isotopic compositions at high spatial resolution; and climate change (including tracing ocean circulation in the past and reconstructing past ocean nutrient distributions).

该奖项为购买新型多收集器电感耦合等离子体质谱仪 (MC-ICP-MS) 仪器提供资金，以支持俄勒冈州立大学 (OSU) 的地球和环境科学前沿研究。购买最新一代 MC-ICP-MS 将对俄勒冈州立大学和太平洋西北地区教师的研究产生直接广泛的影响。支持的研究活动对太平洋西北地区和其他地区的居民具有强大的社会影响，包括气候变化、关键区域过程、人为污染、自然灾害和渔业管理的研究。此次收购将提高地球、海洋和大气科学学院以及农业科学学院 (OSU) 培养高技能毕业生的能力，为各种环境下的职业做好准备。将通过设施参观和仪器演示、课堂项目、学生研究项目和课程练习来支持本科生和研究生的教育和研究。新的 MC-ICP-MS 实现的分析能力将使俄勒冈州立大学保持在快速发展的最前沿高影响力的研究领域。在过去的五年里，质谱仪设计的分析改进不断突破精度和准确度的界限，灵敏度越来越高。这些改进将通过减少所需的样品材料量、提高所有应用的采样分辨率、消除干扰以及同时收集大量同位素，开辟许多新的研究途径。即将提出的将由 MC-ICP-MS 支持的项目的具体例子包括：开发重稳定同位素作为环境应用的工具（例如，检测和量化受污染地下水中的铀去除量；追踪有色金属冶炼排放）；了解关键区域过程（包括追踪土壤输入来源并检查气候、侵蚀和风化之间的关系）；高空间分辨率同位素成分的激光烧蚀测量；和气候变化（包括追踪过去的海洋环流和重建过去的海洋养分分布）。
