Acquisition of a Ground Penetrating Radar

这份拨款为加州大学圣克鲁兹分校地球科学系的探地雷达（GPR）采购提供了部分支持。探地雷达装置将包括五个天线，频率从12.5兆赫到400兆赫。GPR设备将由以下人员使用：(1)UCSC地表过程组（冰川学、地貌学、水文学和第四纪地质学，约占60%的时间），(2)UCSC其他地球科学学院（地球物理、水文地质学和新构造学，约占30%的时间），以及(3)其他UCSC和非UCSC用户（约占10%的时间）。探地雷达技术非常适合上面列出的地球科学研究项目，因为它可以更好地整合地质结构和地层学的地表和近地表观测。这种GPR能力结合了其便携性和易用性，即使在物流困难的环境中，也可以为关键地表和近地表地质过程的约束模型提供出色的工具。除了在研究项目中的应用外，加州大学圣迭戈分校探地雷达设施还将用于加强加州大学圣迭戈分校本科生和研究生在野外地球物理技术方面的实践培训。这种新设备的使用将被纳入高年级的相关课程：地质灾害、环境地球物理、地貌学、土壤性质和力学以及地下水。主机部门将为新建的探地雷达设施提供以下支持：(1)30%的设备成本匹配；(2)探地雷达数据现场处理和后处理的计算机和软件资源；(3)由3名专家组成的团队提供技术支持；(4)存储空间

0132244TulaczykThis grant provides partial support for acquisition of a Ground Penetrating Radar (GPR) for the Department of Earth Sciences at the University of California, Santa Cruz. The GPR setup will include five antennas spanning frequencies from 12.5 MHz through 400 MHz. The GPR equipment will be utilized by: (1) the UCSC Surface Processes Group (glaciology, geomorphology, hydrology and Quaternary geology; ~60% of time), (2) other UCSC Earth Science faculty (geophysics, hydrogeology, and neotectonics; ~30% of time), and (3) other UCSC and non-UCSC users (~10% of time). GPR technology fits ideally into the Earth Science research programs listed above because it permits better integration of surface and near-surface observations of geologic structures and stratigraphy. This GPR capability combines with its portability and ease of use to provide an excellent tool for constraining models of key surface and near-surface geologic processes even in logistically difficult environments. In addition to its application in research projects, the UCSC GPR facility will be used to intensify hands-on training of UCSC undergraduate and graduate students in field geophysical techniques. Use of this new equipment will be incorporated into relevant upper division courses: Geologic Hazards, Environmental Geophysics, Geomorphology, Soil Properties and Mechanics, and Groundwater. The host department will provide support for the new GPR facility in the form of: (1) 30% equipment cost match, (2) computer and software resources for GPR data field processing and post-processing, (3) technical support by a team of three specialists, and (4) storage space.***
