项目摘要

The goal of this project is to develop new methods of analyzing seismic data from densely spaced seismometer arrays, such as EarthScope?s USArray. A key seismological tool for answering the fundamental question of how the mantle circulates is the imaging of seismic discontinuities that are sensitive to the thermal and chemical properties of the mantle. The wealth of data provided by EarthScope allows geoscientists to study the structure of seismic discontinuities on a scale and at a level of detail that have never been possible before. The first phase of this project is funded by the EArly-concept Grants for Exploratory Research (EAGER) program, bringing together a team of seismologists with a broad range of expertise that is led by Dr. Nicholas Schmerr at the University of Maryland and Goddard Space Flight Center. The team is developing a new algorithm and suite of computational tools to analyze seismic energy that reflects from the topside of a seismic discontinuity, providing detailed upper mantle discontinuity structure at scale lengths of several hundred kilometers or less. This tool requires the use of array methodologies enabled by the dense station spacing of the USArray. Development of this new data analysis methodology should stimulate fundamental advances in understanding of the mantle in the fields of mineral physics, mantle petrology, seismology, and geodynamics, adding to the richness of information on the geological history of the mantle beneath the North American continent. The project is providing next-generation open-source scientific research tools, datasets, and measurements made freely available to the scientific community to empower a broader cross section of scientists to handle large datasets such as those provided by EarthScope. These newly developed seismological tools and discontinuity models are being disseminated to the scientific community through the PI?s website.
该项目的目标是开发新的方法来分析密集分布的地震仪阵列,如EarthScope?s USAray。 一个关键的地震学工具,回答如何地幔循环的基本问题是地震不连续性的成像是敏感的地幔的热和化学性质。 EarthScope提供的丰富数据使地球科学家能够以前所未有的规模和详细程度研究地震不连续面的结构。该项目的第一阶段由EARly概念探索研究赠款(EAGER)计划资助,汇集了一个由马里兰州大学和戈达德太空飞行中心的Nicholas Schmerr博士领导的具有广泛专业知识的地震学家团队。 该团队正在开发一种新的算法和一套计算工具,用于分析从地震不连续面顶部反射的地震能量,提供数百公里或更小尺度长度的详细上地幔不连续结构。该工具需要使用由USAray密集站间距支持的阵列方法。这种新的数据分析方法的发展,应刺激在矿物物理学,地幔岩石学,地震学和地球动力学领域的地幔的理解的根本进步,增加了丰富的信息的地质历史的地幔在北美大陆。该项目正在向科学界免费提供下一代开源科学研究工具、数据集和测量数据,以使更广泛的科学家能够处理EarthScope提供的大型数据集。这些新开发的地震学工具和不连续模型正在通过PI?的网站。
