Collaborative research: Implementation of Tensor Visualization guide (TVguide), an interactive visualization, analysis and database tool for seismic anisotropy

这个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可视化变得容易。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，降低来自多个社区的科学家参与地震波研究的门槛，特别是对学生和早期职业科学家。网络工具也将提供方便的课堂使用。该项目将利用该工具组织两次关于地震各向异性的研讨会，重点是为学生和早期职业研究者提供支持，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。地震各向异性对几个地球科学团体的研究人员越来越感兴趣，因为它提供了一种罕见的途径来成像当今和过去的深度变形过程。深部地壳和地幔的变形导致矿物结构的发育，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弹性张量的数据库。该项目将开发一个基于网络的工具，该工具与数据库相连，并提供以下功能：在变形参考系内对数据库中的张量以及用户粘贴的任意弹性张量进行地震参数旋转的交互计算和可视化；2. 张量分解为对称分量和结果的可视化，允许用户回答这样的问题：张量如何很好地表示一个简化的对称，如六边形或正交，在前者的情况下，由快速或缓慢的对称轴；3. 对几种岩石成分或折叠几何形状的体弹性进行平均。考虑到EarthCube等项目正在资助将现场构造地质学和微观结构分析带入大数据领域（例如MacroStrat， Strabo），包括样品的电子背散射衍射（EBSD）图等结果，未来的努力可能会将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。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
