1541588PlanteThis Division of Earth Science Instrumentation and Facilities Program grant supports acquisition of a Netzsch simultaneous Thermal Analyzer for analysis of soil and sediment organic carbon. The requested instrument includes the capabilities for automated operation. The instrument will support studies that investigate the character, stability and content of organic matter in soils, sediments, composts, biochars, and other environmental samples and will allow for high throughput, unattended analysis in support of large-scale soil ecosystem studies. The instrument will support undergraduate and graduate research training. This support is congruent with NSFs mission of promoting the progress of science and advancing the national health, prosperity and welfare given the importance of training the next generation scientific workforce in modern techniques of geochemical oanalysis and research methods and the societal importance of understanding the impacts of changing climate and land use, including agricultural practices, on soil carbon reservoirs.Research using the instrument will allow exploration of the stability and composition of soil organic matter and complement techniques to identify specific soil minerals (XRD), the structure of organic carbon bearing compounds (NMR), and the age of organic carbon pools (AMS radiocarbon dating). The instrument will support studies of a range of soil ecosystems through use on samples from numerous NSF/EAR supported Critical Zone Observatories to better understand the impacts of climate and land use change on soil carbon across space and time.

1541588地球科学仪器和设施计划授予授予授予的授予授予的同时收购Netzsch同时热分析仪，以分析土壤和沉积物有机碳。 请求的仪器包括自动操作的功能。 该仪器将支持研究土壤，沉积物，堆肥，生物齿轮和其他环境样本中有机物的特征，稳定性和含量的研究，并允许对大规模土壤生态系统研究进行高吞吐量，无人参与的分析。 该工具将支持本科和研究生研究培训。 这种支持与NSFS的使命一致，NSFS的使命是促进科学的进步并推进民族健康，繁荣和福利，鉴于培训下一代科学劳动力在现代地球化学序列技术和研究方法中的重要性以及社会对改变气候和陆地上的影响的影响的社会重要性，包括对土壤欧洲的启动的影响，使其对土地上的启动的影响，允许土壤越来越多的工具进行探索，而这些劳动的影响力是对土壤欧洲核心的启动的影响。土壤有机物和补体技术，以鉴定特定的土壤矿物质（XRD），有机碳轴承化合物（NMR）的结构以及有机碳池的年龄（AMS放射性碳年代）。 该仪器将通过在许多NSF/EAR支持的关键区观测器中使用样品来支持一系列土壤生态系统的研究，以更好地了解气候和土地利用变化对跨时空和时间上的土壤碳的影响。
