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

0959524 Cochran该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该主要研究仪器复苏和再投资（MRI-R2）计划资助支持热电离质谱仪（TIMS）和配备激光消融（LA）微探针系统的多收集器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。 七个研究小组的代表，跨越15个科学家的研究兴趣。 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。主要研究领域和新的研究方向包括：利用所要求的MC-ICP-MS对水中微粒进行钍同位素研究，以阐明微粒沉降通量;碎屑锆石和碳酸盐的U-Pb年龄测定，在古气候、古生物和古环境研究中，利用TIMS和MC-2000进行年代学控制的铀系不平衡和Re-Os定年技术，ICP-MS;开发需要热电离质谱法的古盐度锶同位素代用指标;利用镭同位素示踪地下水排入沿海沃茨;利用硼/钙比值和海洋古pH值硼同位素代用指标;风成海洋沉积物的Nd/Sm年代测定和物源研究。新仪器将支持SUNY-SB研究人员，博士后和学生以及外部合作者。现存的SUNY-SB REU计划的目标是课程工具整合，PI计划外展工作，包括与现存的科学和工程妇女（WISE）计划的接口和高中学生通过现有的奖学金计划的参与。所要求的新的工具能力将促进整个校园和外部的合作研究，其中大部分是集中在社会相关的环境和气候变化问题。 ***

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. ***
