MRI-R2: Acquisition of Mass Spectrometers for Earth Systems Science Research at Stony Brook University

该奖项是根据2009年《美国复苏和再投资法案》(Public Law 111-5)资助的。这项重大研究仪器回收和再投资(MRI-R2)计划拨款支持一台热电离质谱仪(TIMS)和一台配备激光烧蚀(LA)微探针系统的多收集器、电感耦合等离子质谱仪(MC-ICPMS)。LA-MC-ICPMS和TIMS仪器将支持在纽约州立大学石溪分校和邻近学术机构开展的一系列研究主题。代表了七个研究小组，涵盖了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。私人投资机构希望建立一个研究中心，支持在地球化学和地质年代学等广泛领域进行跨学科研究。PIS研究的活跃领域和预期的新研究方向包括：为阐明将利用所要求的MC-ICPMS的颗粒下沉通量而进行的水生颗粒物的Th3同位素研究；利用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，以控制古气候的年代学；以及将利用TIMS和MC-ICPMS进行古生物和古环境调查；开发需要热电离质谱仪的古盐度的锶同位素替代物；利用Re同位素示踪剂向沿海水域排放地下水；以及利用海洋中古pH的硼/钙比和硼同位素替代物；风成海洋沉积物的Nd/Sm测年和物源研究。这些新工具将支持纽约州立大学SB分校的研究人员、博士后和学生以及外部合作者。现有的SUNY-SB REU计划的目标是课程工具整合，PIS计划扩大努力，包括与现有的女性科学与工程(WISE)计划的接口，以及通过现有的奖学金计划让高中生参与进来。所需的新工具能力将促进跨校园和外部合作研究，其中大部分集中在与社会相关的环境和气候变化问题上。***

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. ***
