MRI-ACQUISITION OF A SHARED MULTI-COLLECTOR INDUCTIVELY COUPLED MASS SPECTROMETER (MC-ICP-MS) TO BENEFIT TEACHING, FEDERAL, STATE, AND NATIONAL RESEARCH NEEDS IN THE ARCTIC

阿拉斯加州费尔班克斯大学(UAF)被授予在阿拉斯加建立第一个多收集器电感耦合等离子体质谱仪(MC-ICP-MS)设施。这台新仪器将是阿拉斯加同位素设施(AIF)的一部分，并将为在UAF招聘一名新的全职专家研究教员提供支持，该教员接受过使用MC-ICP-MS的培训。这些新资源将用于培训UAF校园内以及阿拉斯加内外的其他学术机构的学生和研究人员。该设施将为来自州和联邦机构的研究人员提供服务，包括美国地质调查局、美国陆军工程兵团和美国鱼类和野生动物服务机构的研究人员。AIF、北方阿拉斯加大学博物馆和阿拉斯加土著健康研究中心将提供高质量的教育和外联机会，涉及公众、K-12学生、农村高中教师、本科生和研究生。新设施将允许对样品进行化学分析，支持研究项目，以更好地了解三文鱼和其他具有商业重要性的鱼类物种的迁徙，揭示北极古代和现代动物的迁徙模式，并提高我们识别阿拉斯加自给自足食物网中重金属污染来源的能力，这对阿拉斯加原住民的文化和健康至关重要。这一新的研究设施将为那些研究北极环境变化的人提供尖端的研究技术，并将加强现有的联邦政府在北极的投资。即将启动的研究领域包括研究重要的经济和文化动物在北极水生和陆地领域的迁徙模式，如鲑鱼、野牛和驯鹿，以应对环境变化。这一新仪器还将支持北极的水文学研究，这些研究反过来又与了解永久冻土的动态以及向大气中释放重要的温室气体，如甲烷和二氧化碳有关。在海洋领域，新的仪器将使研究人员能够研究在生物上必要的元素，这些元素可能限制或共同限制海洋部分地区的生产力，以及其他有毒元素，当通过食物网进行生物放大时，如汞，可能会对较高的营养水平产生负面影响。这一地区对依赖自给自足资源的阿拉斯加土著社区具有特别的文化相关性。

An award is made to the University of Alaska Fairbanks (UAF) to establish the first multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) facility in Alaska. This new instrument will be part of the Alaska Isotope Facility (AIF) and will provide support to recruit a new full-time, expert research faculty member at UAF, trained in using MC-ICP-MS. These new resources will be available to train students and researchers from across the UAF campus, as well as other academic institutions both in and outside of Alaska. The facility will serve researchers from state and federal agencies, including those from the U.S. Geological Survey, U.S. Army Corp of Engineers and U.S. Fish & Wildlife Service. AIF, the University of Alaska Museum of the North and the Center of Alaska Native Health Research, will provide high quality education and outreach opportunities involving the public, K-12 students, rural high school teachers, undergraduate and graduate students. The new facility will allow chemical analyses of samples, supporting research projects to better understand the migration of salmon and other commercially important fish species, to reveal the migration patterns of ancient and modern animals in the Arctic and to advance our ability to identify sources of heavy metal contamination to the subsistence food web in Alaska, which is critical to the culture and health of Alaska Native people. This new research facility will provide cutting-edge research techniques to those studying environmental changes in the Arctic and will enhance existing federal investments in the Arctic. Research areas to be immediately enabled include research into migration patterns of economically and culturally important animals in both Arctic aquatic and terrestrial realms, such as salmon, bison and caribou, in response to environmental changes. This new instrument will also support hydrologic studies in the Arctic, which in turn are linked to understanding permafrost dynamics and the release of important greenhouse gases, such and methane and carbon dioxide, to the atmosphere. In the marine realm, the new instrumentation will enable research to study elements that are biologically necessary and can limit or co-limit productivity in parts of the ocean and others that are toxic and can negatively affect higher trophic levels when biomagnified through food webs, such as mercury. This area has particular cultural relevance for Alaska Native communities that rely on subsistence resources.
