项目摘要

1144043SinghaThis grant supports acquisition of an ten channel electrical resistivity (ER) system (IRIS Syscal Pro) for the Department of Geosciences at Penn State University. ER is sensitive to changes in the electrical conductivity of the shallow subsurface and has applications for spatially and temporally resolved observations of subsurface fluid content and composition. As measured resistances between source and receiver electrodes record the average electrical properties of porous media and conductive fluids along the path length, measurements are a useful complement to discrete in situ sampling and observations from wells. The ER system will support a range of research including remote time series monitoring of hydrologic tracer transport, imaging solute transport between aquifers and stream base flow, studies of groundwater transport in desert ecosystems, and studies of the kinetics of subsurface diagenesis of organics via bacterial iron reduction. The ER system will support research at a Critical Zone Observatory (Shale Hills) and research training through a three-week integrated hydrogeophysics summer course aimed at underrepresented undergraduates from three Historically Black Colleges and Universities partnered with Penn State (Jackson State University, MS; Fort Valley State University, GA; and Elizabeth City State University, NC).***

1144043Singha 这项赠款支持为宾夕法尼亚州立大学地球科学系购置十通道电阻率 (ER) 系统 (IRIS Syscal Pro)。 ER 对浅层地下电导率的变化敏感，可用于地下流体含量和成分的空间和时间分辨观测。由于源电极和接收电极之间的测量电阻记录了沿路径长度的多孔介质和导电流体的平均电特性，因此测量是对离散原位采样和井观察的有用补充。 ER系统将支持一系列研究，包括水文示踪剂输运的远程时间序列监测、含水层和溪流基流之间溶质输运的成像、沙漠生态系统中地下水输运的研究以及通过细菌铁进行有机物地下成岩作用的动力学研究减少。 ER 系统将支持关键区域天文台（页岩山）的研究，并通过为期三周的综合水文地球物理学暑期课程进行研究培训，该课程针对来自与宾夕法尼亚州立大学（杰克逊州立大学，MS；福特堡）合作的三所历史上黑人学院和大学的代表性不足的本科生佐治亚州山谷州立大学；和北卡罗来纳州伊丽莎白城州立大学）。***
