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.

阿拉斯加大学费尔班克斯分校 (UAF) 获得了在阿拉斯加建立第一座多接收器电感耦合等离子体质谱仪 (MC-ICP-MS) 设施的奖项。该新仪器将成为阿拉斯加同位素设施 (AIF) 的一部分，并将为 UAF 招募一名新的全职专家研究教员提供支持，并接受 MC-ICP-MS 使用培训。这些新资源将用于培训 UAF 校园以及阿拉斯加内外其他学术机构的学生和研究人员。该设施将为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与野生动物管理局的研究人员。 AIF、阿拉斯加大学北方博物馆和阿拉斯加原住民健康研究中心将为公众、K-12 学生、农村高中教师、本科生和研究生提供高质量的教育和推广机会。新设施将允许对样品进行化学分析，支持研究项目，以更好地了解鲑鱼和其他具有重要商业价值的鱼类的迁徙，揭示北极古代和现代动物的迁徙模式，并提高我们识别重金属来源的能力。阿拉斯加的生存食物网受到金属污染，这对阿拉斯加原住民的文化和健康至关重要。这个新的研究设施将为研究北极环境变化的人们提供尖端的研究技术，并将加强现有的联邦对北极的投资。立即启动的研究领域包括研究北极水生和陆地领域具有经济和文化重要性的动物（如鲑鱼、野牛和驯鹿）的迁徙模式，以应对环境变化。该新仪器还将支持北极的水文研究，这反过来又与了解永久冻土动力学以及重要的温室气体（例如甲烷和二氧化碳）向大气的释放有关。在海洋领域，新仪器将使研究能够研究生物学上必需的元素，这些元素可以限制或共同限制部分海洋和其他有毒元素的生产力，并且当通过食物网生物放大时可能对更高的营养水平产生负面影响，例如如汞。该地区对于依赖生存资源的阿拉斯加原住民社区具有特殊的文化意义。
