MRI: Acquisition of Side-scan Sonar, Seismic Reflection Profiling, and Differential Global Positioning Sys in Support of Coastal and Shallow Marine Research and Teaching Activities

知识价值：PI正在申请资金，以获得侧面扫描声纳和地震反射剖面系统。该系统将为PI提供对海岸特征进行重复测量的能力，从而能够评估(1)弗吉尼亚堰洲岛链近海的地质和沉积学框架，以及(2)切萨皮克湾河口的河口沉积物运输。拟议的仪器将服务于开发能够预测景观动态的模型，作为沉积物供应、波浪、海平面波动、继承的地质控制和其他因素变化的函数的长期目标。拟议的仪器将主要由PI管理，并得到LTER维护小组和该机构实验室技术人员的支持。更广泛的影响：PI计划将拟议的仪器纳入正在进行的LTER工作（弗吉尼亚海岸保护区，由弗吉尼亚大学主办），该工作吸引小学生和中学生参与实地工作，并为科学教师提供暑期研究生班。该机构的学生作为动手的一部分，本科生的研究工作和课程也将使用拟议的仪器。拟议的仪器还将有助于扩大该机构环境研究项目的研究能力，并进一步促进现有的跨机构合作。

Intellectual Merit:The PI is requesting funds to acquire a side-scan sonar and seismic reflection profiling system. This system will provide the PI the capability to conduct repeated measurements of coastal features, enabling the assessment of (1) the geologic and sedimentological framework offshore of the Virginia barrier island chain, and (2) estuarine sediment transport in Chesapeake Bay sub-estuaries. The proposed instrumentation will serve the long-term goals of developing models capable of predicting landscape dynamics as a function of variations in sediment supply, waves, sea-level fluctuations, inherited geologic controls, and other factors. The proposed instrumentation would be managed primarily by the PI, with support from the LTER maintenance group and a laboratory technician at the institution. Broader Impacts:The PI plans to incorporate the proposed instrumentation into an on-going LTER effort (Virginia Coast Reserve, hosted by the University of Virginia), which engages students primary and secondary school in field efforts, and provides a summer graduate class for science teachers. Students at the institution as part of hands-on, undergraduate research efforts and coursework would also use the proposed instrumentation. The proposed instrumentation would also serve to expand the research capabilities for the Environmental Studies Program at the institution and further enable existing cross-institution collaborations.
