MRI: Acquisition of an Inductively Coupled Plasma Optical Emission Spectrometer at Central Washington University

该主要研究仪器奖为中央华盛顿大学的电感耦合等离子体光发射光谱仪（ICP-OES）的收购提供资金，该大学是一所主要为本科生提供服务的区域综合性大学。这一新仪器将提供对水、酒、气溶胶、土壤、雪和冰芯样本的高质量化学分析，从而能够对地球附近的化学物质如何变化和循环进行一系列跨学科研究。以及它们的存在如何受到人类活动的影响。在地质科学，化学和生物科学部门的四名教师，以及环境研究计划将把新仪器纳入他们的研究，他们的课程，和他们的推广活动。四名教师都有积极的外部资助的研究项目，包括本科生和硕士生;仪器将扩大研究范围和培训这些学生。学院还与地方，地区和国家机构，如国家公园服务，生态，亚卡马国家和环境保护局的华盛顿部门有很强的联系。新工具将加强这些合作，并为学生提供更多与这些外部机构互动的机会。仪器的获取时间与CWU地质科学系占领一座新的科学大楼相吻合。因此，该仪器得到了现代化实验室和相关支持人员的支持，大大增强了新仪器提供的基础设施改进。ICP-OES是一种稳定、可靠的仪器，可以生成水中一系列主要、次要和痕量元素的大量高质量浓度数据;该仪器将提供新的数据，这些数据对于正在进行的环境地球化学/化学、大气科学、气候科学和环境科学研究至关重要，并补充使用现有仪器（例如，同位素比质谱仪、单粒子烟尘光度计、离子色谱仪）。ICP-OES将成为CWU几个研究领域的组成部分，包括水，葡萄酒，气溶胶，土壤以及雪和冰芯样品中的元素浓度。环境地球化学家PI Gazis使用元素数据与其他地球化学示踪剂相结合来表征地下水，以便更好地了解地下水混合，地下水-地表水相互作用以及地下水补给与提取率。她和她的学生还使用元素数据来量化与人为扰动和自然变化（如皆伐，农业，野火和气候）相关的河流和土壤水化学变化。环境化学家Jo-PI Johansen研究气溶胶化学，特别是含碳气溶胶中所含的微量金属如何影响其毒性及其对全球气候的影响。此外，她还是CWU的首席研究员。葡萄酒质量检测实验室，在该实验室中，葡萄酒的化学成分，包括元素分析，与葡萄酒风土和葡萄酒的特征和缺陷进行比较。卡斯帕里是一位气候科学家，他利用冰芯的地球化学记录来重建过去的气候和环境变化。此外，卡斯帕里还研究了黑碳和其他杂质在冰雪上的沉积是如何减少融化和加速融化的。Co-PI Arango研究水生生态系统中的营养循环以及这些循环对河流恢复和金属沉积等扰动的反应。所有这些研究领域都将受益于ICP-OES可以提供的基本地球化学数据。此外，该仪器将为这些科学家在其重叠研究领域（如雪和降水化学、溪流内和周围的地球化学循环以及大气/气候相互作用）开展新的合作创造机会。

This Major Research Instrumentation award provides funding for the acquisition of an Inductively Coupled Plasma Optical Emission Spectometer (ICP-OES) at Central Washington University, a regional comprehensive university that serves primarily undergraduates. This new instrument will provide high-quality chemical analyses of water, wine, aerosol, soil, snow and ice core samples, allowing for a range of interdisciplinary research on how chemicals vary and cycle near the Earth?s surface and how their presence is influenced by human activity. Four faculty members in the Geological Sciences, Chemistry, and Biology Sciences Departments, and the Environmental Studies Program will incorporate the new instrument into their research, their classes, and their outreach activities. The four faculty members all have active externally-funded research programs that include undergraduate and Masters students; the instrumentation will broaden the research scope and training for these students. The faculty also have strong ties with local, regional and national agencies such as the National Park Service, the Washington Department of Ecology, the Yakama Nation, and the Environmental Protection Agency. The new instrument will enhance these collaborations and provide more opportunities for students to interact with these external agencies. The instrument acquisition is timed to coincide with the occupation of a new science building by the Geological Sciences Department at CWU. As such, the instrument is supported by the addition of modern laboratories and associated support staff, greatly amplifying the infrastructure improvements provided by the new instrumentation. The ICP-OES is a stable, reliable instrument that can generate large quantities of high-quality concentration data for a range of major, minor and trace elements in water; this instrument will provide new data that is fundamental for ongoing research in environmental geochemistry/chemistry, atmospheric science, climate science, and environmental science and complements data that can be obtained using existing instrumentation (e.g., isotope ratio mass spectrometer, single particle soot photometer, ion chromatograph) at CWU. The ICP-OES will be integral to several lines of research at CWU that include elemental concentrations in water, wine, aerosol, soil, and snow and ice core samples. PI Gazis, an environmental geochemist, uses elemental data combined with other geochemical tracers to characterize groundwater in order to better understand groundwater mixing, groundwater-surface water interactions and groundwater recharge versus withdrawal rates. She and her students have also used elemental data to quantify changes in stream and soil water chemistry related to anthropogenic perturbations and natural variations such as clear-cutting, agriculture, wildfire, and climate. Co-PI Johansen, an environmental chemist, studies aerosol chemistry, in particular how trace metals contained within carbonaceous aerosols affect their toxicity and their effects on global climate. In addition, she is a principle researcher in CWU?s wine quality testing laboratory in which the chemistry of wines, including elemental analysis, is compared to the wine terroir and wine characteristics and faults. Co-PI Kaspari is a climate scientist who uses geochemical records from ice cores to reconstruct past climate and environmental variability. Additionally Kaspari studies how the deposition of black carbon and other impurities on snow and ice reduces albedo and accelerates melt. Co-PI Arango studies nutrient cycling in aquatic ecosystems and the response of these cycles to perturbations such as stream restoration and metal deposition. All of these areas of research will benefit from the fundamental geochemical data that an ICP-OES can provide. In addition, this instrument will create opportunities for new collaborations between these scientists in their areas of overlapping research interests such as snow and precipitation chemistry, biogeochemical cycles in and around streams, and atmosphere/climate interactions.
