0926171Frank"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." This award will contribute to purchasing a coulometric inorganic carbon analyzer. The analyzer will be used to measure total carbon (TC), total organic carbon (TOC) and total inorganic carbon (TIC). The instrument will be employed in paloclimatology and paleoenvironmental science using samples from terrestrial, marine and lacustrine systems. The early career PI has considerable experience with the requested instrumentation and will oversee purchase, set-up, maintenance and operation. The Department of Geosciences will provide 15% matching funds, and will support all infrastructure costs and long-term repair costs post-warranty. The PI will train new users and establish a nominal per sample fee to cover expendables and supplies. The PI will use the new instrumentation in understanding the biogeochemistry of the late Paleozoic ice age by analyzing the extent and duration of ice sheet events and the end-Permian biotic crisis. Additionally, carbon measurements will support the Antarctic Geologic Drilling Program. The PI will investigate the diagenic processes recorded in ice cores by extracting and analyzing pore-waters. Sediment samples have also been taken for analysis. Diagenesis will also be assessed in carbonate mounds by analyzing carbon speciation. Aragonite removal (or preservation) will be determined as a proxy for environmental conditions. Similarly, conditions by which aragonite skeletal remains are preserved will also assessed by analyzing cores from other locations. The instrumentation will provide a unique regional resource for the PI and other collaborative researchers. Results will be widely disseminated through the literature and at meetings. Student researchers will be trained and given access to the instrumentation. Class projects will also be supported. ***

这个奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。这项奖励将有助于购买库仑无机碳分析仪。该分析仪将用于测量总碳(TC)、总有机碳(TOC)和总无机碳(TIC)。该仪器将用于古气候学和古环境科学，使用陆地、海洋和湖泊系统的样本。职业生涯初期的PI在所要求的仪器方面有相当丰富的经验，并将监督采购、安装、维护和操作。地球科学部将提供15%的配套资金，并将支持所有基础设施费用和保修后的长期维修费用。PI将培训新用户，并制定象征性的按样品收费，以涵盖消耗品和用品。PI将通过分析冰盖事件的范围和持续时间以及二叠纪末的生物危机，使用新的仪器来了解晚古生代冰期的生物地球化学。此外，碳测量将支持南极地质钻探计划。PI将通过提取和分析孔隙水来研究冰芯中记录的成岩过程。还采集了沉积物样本进行分析。成岩作用也将通过分析碳形态来评估碳酸盐丘中的成岩作用。文石的去除(或保存)将被确定为环境条件的替代。同样，文石骨骼遗骸保存的条件也将通过分析其他地点的岩心进行评估。该仪器将为国际和平研究所和其他合作研究人员提供独特的区域资源。结果将通过文献和会议广泛传播。学生研究人员将接受培训，并获得使用仪器的机会。课堂项目也将得到支持。***
