This project will develop a web-based tool that allows for easy visualization of seismic wave propagation through the earth. By offering instant access to analysis, visualization, and rock-based data, this tool will foster cross-disciplinary research and lower the threshold for scientists from several communities to engage with seismic wave studies, particularly for students and early career scientists. The web tool will also provide easy classroom use. The project will organize two workshops on seismic anisotropy using the tool, focusing on support for student and early career investigators, as well as development of a teaching module that will be made available through the Carleton College Science Education Resource Center (SERC) repository. The project will fund an undergraduate research assistant and a female scientific team. Seismic anisotropy is of increasing interest to researchers from several Earth science communities because it offers a rare avenue to imaging present-day and past deformation processes at depth. Deformation in the deep crust and mantle leads to the development of mineral fabric which produces seismic anisotropy. This team of researchers hold a database of crustal rock-based elasticity tensors. This project will develop a web-based tool that ties to the database and offers the following capabilities: 1. Interactive calculation and visualization with rotation of seismic parameters for tensors in the database within a deformation reference frame, as well as of any elasticity tensor pasted in by the user; 2. Tensor decomposition into symmetry components and visualization of results, allowing the user to answer questions such as how well the tensor is represented by a simplified symmetry such as hexagonal or orthorhombic, and in the former case by a fast or slow symmetry axis; 3. Averaging of bulk elasticity over several rock compositions or folded geometries. Given that there are several ongoing efforts funded by programs such as EarthCube to bring field structural geology and microstructural analysis into the big data domain (e.g., MacroStrat, Strabo), including results such as electron backscatter diffraction (EBSD) maps of samples, a future effort could tie the web tool to be developed to such projects in order to provide elasticity tensor analysis based on data held in these applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将开发一个基于网络的工具，使地震波在地球上传播的情况易于可视化。通过提供即时访问分析，可视化和基于岩石的数据，该工具将促进跨学科研究，并降低来自多个社区的科学家参与地震波研究的门槛，特别是对于学生和早期职业科学家。该网络工具还将提供方便的课堂使用。该项目将使用该工具组织两个关于地震各向异性的研讨会，重点是支持学生和早期职业调查人员，以及开发一个教学模块，该模块将通过卡尔顿学院科学教育资源中心（SERC）存储库提供。该项目将资助一名本科生研究助理和一个女性科学团队。地震各向异性越来越受到来自几个地球科学团体的研究人员的关注，因为它提供了一种罕见的途径来成像现在和过去的深度变形过程。地壳和地幔深部的变形导致矿物组构的发育，从而产生地震各向异性。这组研究人员拥有一个基于地壳岩石的弹性张量数据库。该项目将开发一个基于网络的工具，该工具与数据库相关联，并提供以下功能：1。交互式计算和可视化，在变形参考系内旋转数据库中张量的地震参数，以及用户粘贴的任何弹性张量; 2.张量分解成对称分量和结果的可视化，允许用户回答诸如张量如何由简化对称（如六边形或正交）表示以及在前一种情况下由快或慢对称轴表示的问题; 3.几种岩石成分或褶皱几何形状的体弹性平均值。考虑到有几个正在进行的努力，如EarthCube计划资助，将野外结构地质学和微观结构分析纳入大数据领域（例如，MacroStrat，Strabo），包括诸如样品的电子背散射衍射（EBSD）图等结果，未来的努力可以将开发的网络工具与这些项目联系起来，以便根据这些应用程序中保存的数据提供弹性张量分析。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
