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.***

0092002FREEMANITHIS GRANT在宾夕法尼亚州立大学的稳定同位素地球化学实验室中为技术援助提供了三年的部分工资支持。 技术帮助将运行和维护一个由六个气体源稳定的同位素比率质谱仪和相关外围设备（即气相色谱，元素分析仪，真空线）组成的设施。 此外，技术人员将培训新的用户和学生，并使用连续流技术开发新技术，以对地质样本的氢，氧，碳和氮同位素比例进行更具体的分析，包括在现代和晶状体和晶状体，雌激素，河口和淡淡的野生和纯净的冰芯和碳酸盐中遮挡的大气气体，以及有机体和有机物和碳酸盐。 该实验室将促进的研究重点是研究碳，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。***
