This Major Research Instrumentation award provides for the acquisition of geochemical instrumentation which will serve faculty and undergraduate student needs within the Claremont University Consortium (CUC), providing rapid and cost-efficient instrumentation to analyze chemical composition in a wide range of rock, soil, sediment, seawater, and biological materials. This instrumentation will substantially accelerate activities within the research programs of faculty as well as foster interdisciplinary collaboration. The ICP-OES will expand the analytical facilities of the Environmental Science, Biology, Chemistry, and Geology programs and will strengthen collaborative teaching and research among the students and faculty in diverse disciplines from separate institutions. Acquisition of the instrumentation will directly serve a diverse group of undergraduate STEM and non-science majors through integrated lab work in courses and individual student research training. In-house instrumentation will greatly enhance students? ability to directly and clearly connect first-hand scientific training and research to real-world concerns with scientific, environmental, and/or social benefits. The instrument will be housed at the W.M. Keck Science Department of Claremont McKenna, Pitzer, and Scripps Colleges, and faculty at each of the five Claremont Colleges (including Harvey Mudd and Pomona) will use the complete analytical system to train an economically and socially diverse group of STEM and non-science undergraduates on analytical instrumentation, data acquisition, processing, and interpretation. Training in geochemical analysis will help foster success for graduates who go on to work in industry or conduct graduate research.Specifically, this award funds the acquisition of an Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) instrument, coupled to a laser ablation (LA) inlet system and microwave digester. The LA-ICP-OES and microwave digester will allow researchers to generate paleo-reconstructions of seawater temperature and elemental cycling from the skeletons of long-lived organisms to understand variability within our climate and ocean systems, trace the progression of ancient mining and human movements with trace element time series derived from speleothems and fossil teeth, constrain the compositional suitability of barite in soils for Ar/Ar geochronology to help generate a new partial chronology for Pliocene-Holocene climate records in the desert Southwest, analyze feldspar and hornblende to unravel crystal growth stages and mineral responses to changing magmatic and metamorphic conditions and in analyses to understand cycling of nutrients during the Cambrian explosion. Additional users will also incorporate analyses by ICP-OES into their research and teaching programs. Academically, the instrumentation will be used to measure soil chemical compositions in the core course required of all non-science environmental analysis majors and minors at Claremont, and in an upper division soil science course. Senior thesis students and upper level science students at all five CUC colleges will use the instrumentation to measure heavy metals in a variety of materials to determine product origins and interpret potential consumer health impacts. Similarly, the instrumentation will support a pilot group-thesis project to measure suspended sediments in rivers in Costa Rica. Thus, this ICP-OES will provide hands-on undergraduate training through both structured laboratory activities and original student-faculty research.

该主要研究仪器奖提供了地球化学仪器的收购，这将服务于教师和本科生的需求在克莱蒙大学联盟（CUC），提供快速和具有成本效益的仪器分析化学成分在广泛的岩石，土壤，沉积物，海水和生物材料。这种仪器将大大加快教师的研究计划内的活动，以及促进跨学科的合作。ICP-OES将扩大环境科学，生物学，化学和地质学项目的分析设施，并将加强来自不同机构的不同学科的学生和教师之间的合作教学和研究。仪器的收购将通过课程中的综合实验室工作和个别学生的研究培训，直接服务于本科STEM和非科学专业的多元化群体。内部仪器仪表将大大提高学生？能够直接和明确地将第一手的科学培训和研究与现实世界的科学，环境和/或社会效益联系起来。仪器将存放在W.M.。克莱蒙麦肯纳、皮策和斯克里普斯学院的凯克科学系以及五所克莱蒙学院（包括哈维·穆德和波莫纳）的教师将使用完整的分析系统，在分析仪器、数据采集、处理和解释方面培训一批经济和社会多样化的STEM和非科学本科生。地球化学分析培训将帮助毕业生在工业工作或进行研究生研究中取得成功。具体而言，该奖项资助购买电感耦合等离子体发射光谱仪（ICP-OES），耦合到激光消融（LA）入口系统和微波消解器。LA-ICP-OES和微波消化器将使研究人员能够从长寿生物的骨骼中生成海水温度和元素循环的古重建，以了解我们的气候和海洋系统中的变化，追踪古代采矿和人类运动的进展，来自洞穴沉积物和化石牙齿的微量元素时间序列，限制Ar/Ar地质年代学中土壤中重晶石的成分适合性，以帮助生成西南沙漠上新世-全新世气候记录的新的部分年代学，分析长石和角闪石，以揭示晶体生长阶段和矿物对不断变化的岩浆和变质条件的反应，并在分析中了解寒武纪大爆发期间的营养循环。其他用户也将把ICP-OES的分析纳入他们的研究和教学计划。在学术上，仪器将用于测量土壤化学成分的核心课程所需的所有非科学环境分析专业和未成年人在克莱蒙，并在上层司土壤科学课程。所有五所CUC学院的高年级论文学生和高水平理科学生将使用仪器测量各种材料中的重金属，以确定产品来源并解释潜在的消费者健康影响。同样，该仪器将支持一个试点小组论文项目，以测量哥斯达黎加河流中的悬浮沉积物。因此，该ICP-OES将通过结构化的实验室活动和原始的师生研究提供动手本科培训。
