0959524CochranThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Major Research Instrumentation Recovery and Reinvestment (MRI-R2) Program grant supports a thermal ionization mass spectrometer (TIMS) and a multi-collector, inductively coupled plasma mass spectrometer (MC-ICP-MS) equipped with a laser ablation (LA) microprobe system. The LA-MC-ICP-MS and TIMS instrumentation will support a wide array of research themes undertaken at SUNY-Stony Brook and adjacent academic institutions. Seven research groups are represented, spanning 15 scientist's research interests. Research fields include marine geochemistry, paleoceanography, environmental geochemistry, hydrogeochemistry, paleoclimatology, paleontology, toxicology, geochronology, and igneous petrology. The PIs wish to establish a research center which will support interdisciplinary research in the broad areas of geochemistry and geochronology. Active areas of PIs research and intended new research directions include: Thorium isotopic studies of aquatic particulates in order to elucidate particulate sinking fluxes which would utilize the requested MC-ICP-MS; age dating of detrital zircons and carbonates using U-Pb, U-series disequilibria and Re-Os dating techniques for geochronologic control in paleoclimate and paleontologic and paleoenvironmental investigations which would utilize both the TIMS and MC-ICP-MS; development of Strontium isotopic proxies of paleosalinity requiring thermal ionization mass spectroscopy; the use of Radium isotopic tracers of groundwater discharge into coastal waters; and the use of Boron/Calcium ratios and Boron isotopic proxies of paleo-pH in the ocean; and Nd/Sm dating and provenance studies of eolian marine sediments. The new instruments will support SUNY-SB researchers, post-docs and students as well as outside collaborators. Extant SUNY-SB REU programs are targeted for curriculum instrument integration, PIs plan outreach efforts to include interface with an extant Women in Science and Engineering (WISE) program and engagement of High school students through an existing fellowship program. The requested new instrumental capabilities will foster across campus and external collaborative research, much of which is focused on societally-relevant environmental and climate change issues. ***

0959524Cochran该奖项根据 2009 年美国回收和再投资法案（公法 111-5）提供资金。这项主要研究仪器回收和再投资 (MRI-R2) 计划拨款支持热电离质谱仪 (TIMS) 和多收集器、配备激光烧蚀 (LA) 微探针系统的电感耦合等离子体质谱仪 (MC-ICP-MS)。 LA-MC-ICP-MS 和 TIMS 仪器将支持纽约州立大学石溪分校和邻近学术机构开展的广泛研究主题。 共有 7 个研究小组代表，涵盖 15 名科学家的研究兴趣。 研究领域包括海洋地球化学、古海洋学、环境地球化学、水文地球化学、古气候学、古生物学、毒理学、地质年代学和火成岩岩石学。 PI 希望建立一个研究中心，支持地球化学和地质年代学广泛领域的跨学科研究。 PI 研究的活跃领域和预期的新研究方向包括： 对水生颗粒物进行钍同位素研究，以阐明颗粒物下沉通量，这将利用所要求的 MC-ICP-MS；使用 U-Pb、U 系列不平衡和 Re-Os 测年技术对碎屑锆石和碳酸盐进行年龄测定，以利用 TIMS 和 MC-ICP-MS 进行古气候、古生物和古环境研究中的地质年代学控制；开发需要热电离质谱的古盐度的锶同位素代理；使用镭同位素示踪剂追踪流入沿海水域的地下水；以及海洋中古 pH 值的硼/钙比和硼同位素代理的使用；风成海洋沉积物的 Nd/Sm 测年和物源研究。新仪器将为 SUNY-SB 研究人员、博士后和学生以及外部合作者提供支持。现有的 SUNY-SB REU 项目旨在整合课程工具，PI 计划外展工作，包括与现有的科学与工程女性 (WISE) 项目对接，以及通过现有的奖学金项目吸引高中生参与。所要求的新工具能力将促进跨校园和外部的合作研究，其中大部分重点关注与社会相关的环境和气候变化问题。 ***
