Imaging Science Workshops for USArray

我们提议在三年内举办一系列三期讲习班，重点是利用密集分布的宽带地震仪阵列记录的地震进行散射波成像的主题，特别是使用美国阵列的数据。这些研讨会将由一个指导委员会组织，并随着系列赛的进展与参与的科学家合作开发。这些研讨会将被广泛宣传，并将向任何有兴趣参加的人开放。研讨会将通过创建一个科学家和学生的虚拟中心来加速散射波成像技术的发展。该虚拟中心将积极邀请参与这项研究的科学家和学生参加一个交流思想、联合开发软件以及交换实地和合成数据集的工作论坛。工作坊和研究主题将包括1)调查在制定成像算法时使用的近似对最终图像的影响，2)使用现场和合成数据测试和验证区分方法，3)实验设计准则，4)地震速度分析，5)将图像与地球的组成和物理状态联系起来。工作坊将为参与这一研究领域的毕业生(和高级科学家)提供工作课程。这将在新一代年轻科学家中建立社区，他们将成为地震学的下一批理论领袖，并将从地球望远镜的努力中获益。与其他情况相比，学术和工业背景的人的协同作用将更快地推动该领域的发展。这种改善的交流将有助于促进学术和工业研究社区的知识，并加强这些群体之间的相互影响。

We are proposing a series of 3 workshops to be held over three years focusing on the subjectof scattered wave imaging using earthquakes recorded by densely spaced broadbandseismograph arrays, and particularly using the USArray data. The workshops will be organizedby a steering committee, and developed in cooperation with the participating scientists as theseries progresses. The workshops will be advertised broadly and will be open to anyoneinterested in attending.The workshops will be designed to accelerate the development of scattered wave imagingtechniques by creating a virtual center of scientists and students. The virtual center will activelyengage scientists and students involved in this research in a working forum for exchange ofideas, joint development of software, and exchange of field and synthetic datasets. Workshopand study topics will include 1) investigation of the effects of the approximations used informulating imaging algorithms on the final images, 2) testing and validation of differentimaging methods using field and synthetic data, 3) experiment design criteria, 4) seismic velocityanalysis, and 5) relating the images to composition and physical state of the Earth.The workshops will be designed to include working classes for graduatestudents (and senior scientists) involved in this research area. This will build community in thenew generation of young scientists who are emerging as the next group of theoretical leaders inseismology, and who will reap the benefits of the Earthscope endeavor. The synergy of bringingpeople from academic and industrial backgrounds will advance the field more rapidly than ispossible otherwise. This improved communication will help advance knowledge in both theacademic and industrial research communities and enhance cross-fertilization between thesegroups.
