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.

该合同用于采购新仪器，以支持采购用于各种环境样品痕量元素分析的新LA-HR-ICPMS仪器。该仪器将取代安装在缅因州大学气候变化研究所（CCI）的原始（二十多年来大量使用）ThermoScientific Element 2 ICP-MS。此次新收购将显著扩大CCI/ICP-MS设施的研究能力，以改善水溶液样品的分析，并补充用于冰，生物和其他固体材料的激光消融（LA）前端。目前的ICP-MS设施成立于2002年，获得了NSF/MRI奖，从那时起，它一直是美国气候，环境，生态系统和工程研究和培训的重要资源。缅因州，整个缅因州和更远的地方。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，他们的研究领域分为三个：冰川化学和气候/环境重建;古海洋学和海洋生物地球化学;环境传感器开发和材料科学工程。缅因州是国家的陆地海洋补助大学和唯一的博士授予机构，所以校园是缅因州事实上的学术研究和研究培训中心。这种研究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家和国际合作。具体到这个建议是与威尼斯大学（意大利）和剑桥大学/英国南极调查局合作开发冰芯的激光消融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缅因州湾和南太平洋的NSF资助的研究项目产生直接影响。拟议的仪器将促进学术学院之间新的重要合作（自然科学，林业和农业学院和工程学院）和研究单位-CCI和传感器技术研究前沿研究所-遍布校园，以及使新的和更广泛的科学合作与其他学术和科学机构在缅因州。这个奖项反映了NSF的法定基金会的使命是履行其使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评价，被认为值得支持。
