Imaging Science Workshops for USArray

我们建议在三年内举办一系列的3个讲习班，重点讨论利用密集分布的宽带地震仪阵列记录的地震，特别是利用USAray数据进行散射波成像的问题。这些讲习班将由一个指导委员会组织，并随着系列的进展与参与的科学家合作发展。研讨会将广泛宣传，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。虚拟中心将积极吸引参与这项研究的科学家和学生参加工作论坛，以交流想法，共同开发软件，交换实地和合成数据集。研讨会和研究的主题将包括1）在最终图像上制定成像算法时使用的近似效果的调查，2）使用现场和合成数据测试和验证差分成像方法，3）实验设计标准，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。工作坊将包括为研究生开设的工作课（和资深科学家）参与这一研究领域。这将在新一代的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导者，并将从Earthscope的奋进中获益。来自学术界和工业界背景的人的协同作用将比其他方式更快地推动该领域的发展。这种改进的交流将有助于推进学术界和工业研究界的知识，并加强这些群体之间的交流。

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.
