Technician Support: The Penn State Stable-Isotope Biogeochemistry Laboratory

这笔赠款为宾夕法尼亚州立大学稳定同位素地球化学实验室的技术援助提供了三年的部分工资支持。技术援助将运营和维护一个设施，该设施由6个气源稳定同位素比质谱仪和相关外围设备(即气相色谱仪、元素分析仪、真空管)组成。此外，技术人员将培训新的用户和学生，并开发利用连续流动技术的新技术，用于对地质样品的氢、氧、碳和氮同位素比率进行复合特定分析，包括封闭在冰芯中的大气气体和现代和岩化的海洋、河口和淡水沉积物中的碳酸盐。将在该实验室推动的研究重点是碳、氮和氢的生物地球化学循环以及温室气体、全球气候以及陆地和海洋生态系统之间的反馈。

0092002FreemanThis grant provides three years of partial salary support for technical assistance in the stable isotope geochemistry laboratories at Penn State University. Technical help will operate and maintain a facility consisting of six gas-source stable isotope ratio mass spectrometers and associated peripherals (i.e. gas chromatographs, elemental analyzers, vacuum lines). Additionally, technician will train new users and students and develop new techniques utilizing continuous flow technology for compound specific analysis of Hydrogen, Oxygen, Carbon and Nitrogen isotope ratios of geological samples including atmospheric gases occluded in ice cores and organics and carbonates in modern and lithified marine, estuarine and freshwater sediments. Research that will be facilitated at this lab is focused on studies of the biogeochemical cycling of carbon, nitrogen and hydrogen and the feedbacks between greenhouse gases, global climate, and terrestrial and marine ecosystems.***
