0841901KirbyThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This grant supports acquisition of ground penetrating radar (GPR) equipment, a real-time kinematic GPS system, 3-D visualization software and field hardened notebook computers. The equipment will support research and research training in the Department of Geosciences at Penn State University that will benefit from the capability of GPR to image the near subsurface. Specific equipment to be purchased includes a GPR system with multiple borehole antennas (at frequencies of 50, 100 and 200 MHz) to support stratigraphic, tectonic and hydrologic studies and a high frequency pulsed GPR system to be deployed for imaging the thickness, internal structure and basal contacts of glaciers. The equipment will support a range of PI and student research including studies of the dynamics of rivers of ice draining the West Antarctic Ice Sheet, studies of the movement of solutes through ground water systems, morphodynamic investigations of meandering and braided river systems, studies of pedogenesis and hill slope processes, and paleoseismological investigations of buried faults near active plate margins. In particular, research use of the GPR systems for study of the response of polar continental ice sheets to climate change is of profound and timely societal interest. GPR, in conjunction with seismic reflection techniques, offers the means to image glacial structure at high resolution to hundreds of meters and to probe the structure and nature of underlying deposits that serve to lubricate or slow glacial advance toward the sea. Students trained in GPR operation, data analysis and interpretation are well poised to gain employment in a host of civil engineering and environmental consulting fields that increasingly rely on GPR as a tool for near subsurface imaging.

0841901KirbyThis奖是根据2009年《美国回收与再投资法》（公法111-5）资助的。这笔赠款支持收购地面穿透性雷达设备（GPR）设备，实时运动学GPS系统，3-D可视化软件和现场硬化计算机。 该设备将支持宾夕法尼亚州立大学地球科学系的研究和研究培训，这些研究将从GPR的能力中受益到近地下。 要购买的特定设备包括具有多个井眼天线的GPR系统（以50、100和200 MHz的频率为频率），以支持地层，构造和水文研究，以及用于部署的高频脉冲GPR系统，用于成像冰川的厚度，内部结构和基础接触。 该设备将支持一系列PI和学生研究，包括研究冰河河流动力学的研究，对南极西部冰盖的河流动力学，对溶质通过地下水系统运动的研究，对蜿蜒和编织河流系统的形态动力学研究，对人的养殖和丘陵坡度的研究，以及近乎活跃的板层覆盖层床的古s坡过程的研究。 特别是，研究使用GPR系统来研究极地大陆冰盖对气候变化的反应是深刻而及时的社会利益。 GPR与地震反射技术结合使用，提供了以高分辨率为数百米的冰川结构对冰川结构进行图像的方法，并探究了基础沉积物的结构和性质，这些沉积物的结构和性质可用于润滑或慢慢冰川向海洋前进。 接受GPR操作，数据分析和解释培训的学生有望在许多土木工程和环境咨询领域获得就业，这些领域越来越依赖GPR作为近地下成像的工具。
