Technician Support: The Penn State Stable-Isotope Biogeochemistry Laboratory

[00:92002 . freemann]这笔拨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。技术援助将操作和维护一个由六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、真空线）组成的设施。此外，技术人员将培训新用户和学生，并利用连续流技术开发新技术，对地质样品的氢、氧、碳和氮同位素比率进行复合具体分析，包括冰芯中封闭的大气气体、现代和石化海洋、河口和淡水沉积物中的有机物和碳酸盐。该实验室将重点研究碳、氮、氢的生物地球化学循环，以及温室气体、全球气候、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.***
