With this award, the PIs and faculty colleagues at UNH and other Northern New England institutions will acquire a multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS) to carry out high-precision isotopic measurements for a variety of elements applicable to studies in the Earth and environmental sciences. Isotopic characterization of Earth and environmental materials continues to revolutionize our capability to track and quantify processes as well as understand elemental fluxes between different reservoirs of the Earth system. Isotopic data are also critical to deciphering the timing of major events in Earth history that profoundly impact the evolution of life, Earth?s climate and the physical development of the continents, ocean basins and the planet?s interior. Projects capitalizing on this facility will include: (1) advancement and enhancement of the quantitative model for the isotopic consequences of partial melting of Earth?s crust; (2) geochemical assessment of mantle melting dynamics; (3) isotopic characterization of soil minerals, fungal material, and tree tissues from novel biogeochemical experiments designed to develop elemental and isotopic proxies for nutrient limitation; (4) early evolution of Earth?s mantle and lithosphere, as recorded by silicic and ultramafic rocks in early Archean cratons; (5) geochronologic and tracer studies to quantify the rates and mechanisms of crustal processes, with emphasis on modern plate boundaries and past orogenic events; (6) isotopic tracer applications to elucidate sediment provenance; (7) geochronologic and tracer applications to constrain environmental change in Earth?s history; (8) hydrogeological applications of isotopic ratios to identify surface and ground water interactions and anthropogenic contributions to mixed-use watersheds; and (9) isotopic tracking of air mass provenance and atmospheric chemical reactions. Broader impacts of this analytical facility will include student training, innovation of new analytical techniques, and the strengthening (and development) of research ties between several New England institutions. Data collected in this facility will foster the growth of quantitative models for characterizing varied deep Earth, Earth surface, deep time and atmospheric processes.

有了这一奖项，公共关系研究所和新英格兰大学北部其他机构的教职员工将获得一台多收集器电感耦合等离子体质谱仪(MC-ICP-MS)，对适用于地球和环境科学研究的各种元素进行高精度同位素测量。地球和环境材料的同位素特征继续改变着我们追踪和量化过程以及了解地球系统不同储藏库之间的元素通量的能力。同位素数据对于破译地球历史上重大事件的时间也是至关重要的，这些事件深刻地影响了生命的演化、地球的气候以及大陆、海洋盆地和地球内部的物理发展？S。利用这一设施的项目将包括：(1)改进和加强地球？S地壳部分熔融的同位素后果的定量模型；(2)地幔熔融动力学的地球化学评估；(3)土壤矿物、真菌材料和树木组织的同位素表征，这些实验旨在开发营养限制的元素和同位素替代物；(4)地球？S地幔和岩石圈的早期演化，如早期太古代克拉通中的硅质和超镁铁质岩石记录的；(5)地质年代学和示踪研究，以量化地壳过程的速率和机制，重点是现代板块边界和过去的造山事件；(6)同位素示踪剂在阐明沉积物来源方面的应用；(7)地质年代学和示踪剂在限制地球环境变化方面的应用？？S历史；(8)同位素比值在水文地质中的应用，以确定地表水和地下水的相互作用以及人类对混合用途流域的贡献；以及(9)大气质量来源和大气化学反应的同位素示踪。这一分析设施的更广泛影响将包括学生培训、新分析技术的创新以及加强(和发展)几个新英格兰机构之间的研究联系。在该设施中收集的数据将促进定量模型的发展，以表征不同的地球深处、地球表面、深层时间和大气过程。
