Early Career: Acquisition of Ground Penetrating Radar

1602192ShepherdThis地球科学仪器和设施计划拨款部门支持在一系列频率范围内购买具有多个天线的探地雷达（GPR）系统，以支持对近地表下结构和属性的非侵入式成像调查。 该仪器将支持奥本地球科学系的研究和研究培训。 首席PI是一位职业生涯早期的女性地球科学家，计划利用所要求的GPR，让亚拉巴马农村地区代表性不足的中学生参与当地相关的环境研究。 这种支持与国家科学基金会促进科学进步和促进国民健康的使命是一致的，考虑到在地球物理遥感现代技术方面培训下一代科学劳动力的重要性以及了解河流恢复计划的影响和美国中部历史地震危害程度的社会重要性，对近地表沉积物的介电特性进行侵入性调查，并可深入了解近地表地层关系和材料特性。 地质雷达将支持第四纪河流过程和景观演变的研究，在影响移动的海湾河口的流域洪泛平原恢复策略的调查，以及在新马德里中部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.
