Physical Insight and Mathematical Methods in Seismic Data Analysis

该补助金支持北卡罗来纳州AT州立大学物理和数学系之间的应用和计算地震学跨学科研究项目。&具体而言，PI将在物理系的地震物理建模和数据处理实验室工作一年，以获得物理洞察力和地震数据采集，处理，先进成像和可视化的知识，并研究数学方法和地震数据分析中的开放问题。拟议的项目活动包括：（1）通过地震物理建模和野外勘测获取地震数据;（2）使用OMEGA地震处理系统和Seismic Unix软件包处理获取的地震数据;（3）通过数学建模和适当制定的用于地震波的二维和三维点源声波方程的数值解来模拟地震数据，（4）研究地震资料分析中的数学方法、研究现状及存在的问题。 预计在他在物理系的一年居住完成后，PI不仅将提高自己在应用和计算地震学方面的专业知识和经验，而且还为PI和他在物理系的两位主持人之间的持续合作奠定了基础，以开发一个定义明确的跨学科地球科学研究计划，该计划将吸引其他数学教师和学生。拟议的项目活动还将促进与休斯顿大学联合地球物理实验室、西部地球物理/贝克休斯公司和金字塔环境公司的协作与合作。以及加强和扩大由NSF HBCU-UP资助的Talent-21项目的地球物理和环境科学教育和研究培训部分。该项目将对提议者所在机构的三个拟议计划倡议产生直接影响：计算科学计划，地球科学计划和跨学科博士学位。计划，所有这些都旨在加强和提升大学的跨学科研究工作。 该IGMS项目由MPS多学科活动办公室（OMA）和数学科学部（DMS）共同支持。

This grant supports an interdisciplinary research project in applied and computational seismology between the Physics and Mathematics Departments at North Carolina A&T State University. Specifically, the PI will spend one year working in the Seismic Physical Modeling and Data Processing Laboratories in the Physics Department to gain physical insight into and knowledge of seismic data acquisition, processing, advanced imaging and visualization, and to study mathematical methods and open problems in seismic data analysis. The proposed project activities include: (1) acquiring seismic data through seismic physical modeling as well as field surveying; (2) processing acquired seismic data using OMEGA Seismic Processing System and Seismic Unix software packages; (3) simulating seismic data through mathematical modeling and numerical solutions of appropriately formulated two- and three-dimensional point source acoustic wave equations for seismic waves, and writing interactive Fortran, C++, Labview, Matlab, OMEGA, and Seismic Unix programming scripts; and (4) studying mathematical methods, current research trend and open problems in seismic data analysis. It is anticipated that upon completion of his one-year residence in the Physics Department, the PI will not only enhance his own expertise and experience in applied and computational seismology, but also lay a foundation for a continuing collaboration between the PI and his two hosts in the Physics Department in developing a well-defined interdisciplinary geosciences research program which will engage other mathematics faculty members and students. The proposed project activities will also further collaborations and cooperation with the Allied Geophysical Laboratories of the University of Houston, Western Geophysical/Baker Hughes Corporation, and Pyramid Environmental, Inc. as well as enhance and expand the geophysical and environmental science education and research training component of the Talent-21 project funded by the NSF HBCU-UP. This project will have immediate impact on three proposed program initiatives at the proposers' institution: a computational science program, a geosciences program, and an interdisciplinary Ph.D. program, all of which aim at strengthening and upgrading the University's interdisciplinary research efforts. This IGMS project is jointly supported by the MPS Office of Multidisciplinary Activities (OMA) and the Division of Mathematical Sciences (DMS).
