This award is for acquisition of new instrumentation to support acquisition of the new LA-HR-ICPMS instrumentation for the trace-element analysis of various environmental samples. This instrumentation will replace the original (and heavily used over two decades) ThermoScientific Element2 ICP-MS installed at the University of Maine’s Climate Change Institute (CCI). The new acquisition will significantly expand research capabilities of the CCI/ICP-MS Facility to improve the analysis of aqueous samples, supplemented with a laser ablation (LA) front end for ice, biological, and other solid materials. The current ICP-MS Facility was established in 2002 with an NSF/MRI award, which since then has served as a vital resource for climate, environmental, ecosystem, and engineering research and training at the U. Maine, across the state of Maine and beyond. The routine use and primary support of the Facility come from the Principal Investigators and their collaborators that group under three research areas: glaciochemistry and climate/environmental reconstruction; paleoceanography and marine biogeochemistry; and environmental sensor development and material science engineering.The U. Maine is the State’s Land & Sea Grant university and only PhD granting institution, so the campus is the de facto academic research and research training hub of the state of Maine. The proposed advances of this research & training instrumentation will immediately impact current and future NSF-funded research projects that support extensive national and international collaborations. Specific to this proposal are collaborations with the University of Venice (Italy) and the University of Cambridge/British Antarctic Survey to develop laser ablation ICP-MS imaging of ice cores, and collaborations with New Zealand, Swiss, Chinese, Canadian, and Brazilian colleagues to analyze ice, thereby maintaining our leadership role in global ice core and climate change research. Likewise, the enhanced carbonate analysis capacity of the Element XR will have an immediate impact on NSF-funded research projects in the Gulf of Maine and in the South Pacific. The proposed instrumentation will facilitate new and important collaborations between academic colleges (College of Natural Science, Forestry, and Agriculture and the College of Engineering) and research units - the CCI and the Frontier Institute for Research in Sensor Technology - across the campus, as well as enabling new and broader scientific collaborations with other academic and scientific institutions across Maine.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项用于购买新仪器，以支持购买新的 LA-HR-ICPMS 仪器，用于各种环境样品的痕量元素分析。该仪器将取代原来的（二十年来大量使用的）ThermoScientific Element2 ICP-MS。安装在缅因大学气候变化研究所 (CCI) 的新收购将显着扩展 CCI/ICP-MS 设施的研究能力，以改进水样分析，并辅以激光烧蚀。 (LA) 冰、生物和其他固体材料的前端 目前的 ICP-MS 设施于 2002 年建立，获得了 NSF/MRI 奖项，从那时起，该设施就成为气候、环境、生态系统和工程的重要资源。该设施的日常使用和主要支持来自主要研究人员及其合作者，他们分为三个研究领域：冰川化学和气候/环境重建；古海洋学和海洋生物地球化学；以及环境传感器开发和材料科学工程。美国缅因州是缅因州陆地与海洋资助大学和唯一的博士学位授予机构，因此该校园是缅因州事实上的学术研究和研究培训中心该研究和培训仪器的拟议进展将立即影响当前和未来的 NSF 资助的研究项目，这些项目支持广泛的国内和国际合作，特别是与威尼斯大学（意大利）和大学的合作。剑桥/英国南极调查局开发冰芯激光烧蚀 ICP-MS 成像，并与新西兰、瑞士、中国、加拿大和巴西的同事合作分析冰，从而保持我们在全球冰芯和气候变化研究中的领导地位。同样，Element XR 增强的碳酸盐分析能力将对 NSF 资助的缅因湾和南太平洋研究项目产生直接影响。拟议的仪器将促进学术学院（自然学院）之间新的重要合作。科学、林业、农业和工程学院）和研究单位 - CCI 和传感器技术前沿研究所 - 遍布整个校园，并与缅因州其他学术和科研机构开展新的、更广泛的科学合作。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
