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. ***

0926171 frank“该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。”该奖项将有助于购买Coulometric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）。该仪器将采用陆地，海洋和湖泊系统的样品中的古气候和古环境科学。 PI早期职业生涯在要求的仪器方面具有丰富的经验，并将监督购买，设置，维护和运营。地球科学系将提供15％的匹配资金，并将支持所有基础设施成本和长期维修成本。 PI将培训新用户并建立每次样本费用，以涵盖消耗品和用品。 PI将利用新仪器来理解晚古生代冰河时代晚期的生物地球化学，并分析冰盖事件的程度和持续时间和最终的佩尔米亚生物危机。此外，碳测量结果将支持南极地质钻探计划。 PI将通过提取和分析毛孔捕获器来研究冰芯中记录的成岩过程。也已经采集了沉积物样品进行分析。成岩作用也将通过分析碳形成在碳酸盐土堆中进行评估。将撤离（或保存）将确定为环境条件的代理。类似地，保留了后者骨骼残留的条件也将通过分析其他位置的核心来评估。该仪器将为PI和其他协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仪器的访问权限。课堂项目也将得到支持。 ***
