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

阿拉斯加大学费尔班克斯（UAF）获得了一个奖项，以在阿拉斯加建立第一个多接收器电感耦合等离子体质谱仪（MC-ICP-MS）设施。这一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，这些教员接受过使用MC-ICP-MS的培训。该设施将为来自州和联邦机构的研究人员提供服务，包括来自美国地质调查局、美国陆军工程公司和美国鱼类野生动物服务局的研究人员。AIF，阿拉斯加大学北方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。新设施将允许对样本进行化学分析，支持研究项目，以更好地了解鲑鱼和其他商业上重要的鱼类物种的迁移，揭示北极古代和现代动物的迁移模式，并提高我们识别重金属污染源的能力阿拉斯加的生计食物网，这对阿拉斯加土著人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提供尖端的研究技术，并将加强现有的联邦在北极的投资。将立即启动的研究领域包括研究在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，为应对环境变化而进行的迁徙模式。这一新仪器还将支持北极的水文研究，而这些研究又与了解永久冻土动态以及甲烷和二氧化碳等重要温室气体向大气层的释放有关。在海洋领域，新的仪器将使研究人员能够研究生物所必需的、可能限制或共同限制海洋部分地区生产力的元素，以及其他有毒元素，如汞，当生物通过食物网迁移时，可能对较高的营养级产生不利影响。这一地区对依赖生存资源的阿拉斯加土著社区具有特殊的文化意义。

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.
