Early Career: Acquisition of Ground Penetrating Radar

1602192 shepherd该地球科学仪器和设施部门计划拨款支持采建一个具有多个频率天线的探地雷达（GPR）系统，以支持对近地下结构和特性的非侵入性成像调查。该仪器将支持奥本大学地球科学系的研究和研究培训。首席项目负责人是一位职业生涯早期的女性地球科学家，她计划利用所要求的探地雷达，让阿拉巴马州农村地区未被充分代表的中学生参与当地相关的环境研究。这种支持与nsf促进科学进步和促进国民健康的使命是一致的。考虑到在现代地球物理遥感技术方面培训下一代科学工作者的重要性，以及了解美国中部河流恢复计划的影响和历史地震灾害程度的社会重要性，繁荣和福利。探地雷达允许对近地表沉积物的介电特性进行非侵入性调查，并可以深入了解近地表地层关系和材料特性。GPR将支持第四纪河流过程和景观演变的研究，对影响莫比尔湾河口的流域洪泛平原恢复策略的调查，以及对新马德里中大陆地震带历史地震引起的地震液化的古地震调查。

1602192ShepherdThis Division of Earth Science Instrumentation and Facilities Program grant supports acquisition of a Ground Penetrating Radar (GPR) system with multiple antennas in a range of frequencies to support non-invasive imaging investigations of the structure and properties of the near subsurface. The instrument will support research and research training in the Department of Geosciences at Auburn. The lead PI is an early career, female geoscientist with plans to engage underrepresented middle school students in rural Alabama in locally relevant environmental research using the requested GPR. 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 geophysical remote sensing and the societal importance of understanding the impacts of river restoration programs and extent of historical seismic hazards in the central U.S.GPR permits non-invasive investigation of the dielectric properties of near surface sediments and can yield insights into near surface stratigraphic relationships and materials properties. The GPR will support studies of Quaternary fluvial processes and landscape evolution, investigation of flood plain restoration strategies in watersheds that impact Mobile Bay Estuary, and paleoseismic investigations of earthquake induced liquefaction from historic earthquakes in the New Madrid mid-continent seismic zone.
