0841739Rowe This proposal seeks funding of ~$31K to purchase a UIC coulometer and acidification module to perform paleoenvironmental research. The system will be able to analyze total organic and total inorganic carbon (TOC and TIC) in water, rock, and soil samples. The PI has experience with this instrument and it will be configured and housed in the stable isotope facility at UT-Arlington. The PI will offer analyses with a small fee structure to allow purchase of supplies and support consumables. The overall research goals for this acquisition revolve around better understanding paleooceanographic conditions. The coulometer will be used to assess DIC and DOC in depositional formations to relate biogeochemical indicators (such as under oxic-anoxic conditions), primarily in high-deposition areas (like ocean basins). Land-derived nutrient loadings will also be assessed through understanding oxic-anoxic conditions in organic-rich sedimentary material. The instrument will also be crucial in examining the geostratigraphy associated with the Permian-Triassic boundary mass extinction. Finally, stream geomorphology will be assessed in recent times by linking hydrological parameters with carbon and elemental biogeochemistry. Data from this instrument will be made available to the community through PaleoStrat and CHRONOS databases. It will be used in an REU program examining coal mining impacts on carbon dynamics in Appalachian streams. This instrument will allow the PI to be more selective for samples needing additional analysis and allow students the opportunity to take vital, but perhaps more straight-forward measurements. The PI will incorporate the instrument into three courses. The PI is well-represented in female and minority students.***

0841739Rowe 该提案寻求约 31,000 美元的资金来购买 UIC 库仑计和酸化模块以进行古环境研究。该系统将能够分析水、岩石和土壤样品中的总有机碳和总无机碳（TOC 和 TIC）。 PI 拥有使用该仪器的经验，它将在 UT-Arlington 的稳定同位素设施中进行配置和安置。 PI 将提供少量费用结构的分析，以允许购买供应品和支持消耗品。此次收购的总体研究目标围绕更好地了解古海洋条件。库仑计将用于评估沉积地层中的 DIC 和 DOC，以关联生物地球化学指标（例如在缺氧条件下），主要是在高沉积区域（如洋盆）。还将通过了解富含有机物的沉积物质中的缺氧条件来评估陆地养分负荷。该仪器对于研究与二叠纪-三叠纪边界大规模灭绝相关的地层学也至关重要。最后，近期将通过将水文参数与碳和元素生物地球化学联系起来来评估河流地貌。该仪器的数据将通过 PaleoStrat 和 CHRONOS 数据库提供给社区。它将用于 REU 项目，研究煤炭开采对阿巴拉契亚溪流碳动态的影响。该仪器将使 PI 能够更有选择性地选择需要额外分析的样品，并让学生有机会进行重要但可能更直接的测量。 PI 将该工具纳入三门课程中。 PI 在女性和少数族裔学生中的比例很高。***
