Intellectual Merit: "Geo is deep earth." While scientists can image deep space and the formation of stars, at present tools do not exist to image even tens of meters into the earth. What is needed is a Hubble telescope into, not away from, the earth - a tool for high resolution imaging of the Earth's interior. Through this award, the Subsurface Imaging and Sensing team will develop, combine, and refine the science necessary to image the earth at the many scales required for the Deep Underground Science and Engineering Laboratory (DUSEL) facility at the Homestake Mine in South Dakota, to use these abilities to gain understanding of rock and rock mass, and to leverage these discoveries into engineering tools. All the earth interrogation methods used by the team rely heavily on inversion methods because the data collected do not directly measure the physical quantity of interest. The proposed suite of experiments combines the power of many methodologies to provide strong constraints on the necessary inversions, and to bring images into sharper focus. The Homestake Mine provides the unique facility which allows this multi-scale and multi-physics campaign to happen. Prior to research commencing, the project team will develop a detailed design for the needed infrastructure and safety procedures. Infrastructure is only one small piece of the massive DUSEL undertaking, and requires a complete a work breakdown structure document. Several workshops will be held, two in order to broaden participation in the project team and involve more of the community in the DUSEL undertaking, and three workshops/design meets at the Homestake mine in Lead to provide real detail and certitude for the overall design process.Broader Impacts: The Subsurface Imaging and Sensing experiments will have two types of impact - societal and technical. Building on the initial contacts made by the PI for his ongoing NSF-supported project at DUSEL, "Towards a Transparent Earth," the observatory, through the Sanford Science and Education Center, will provide a lifelong learning experience for all stakeholders - K-12 students and teachers, the hundreds of thousands of visitors passing through the Black Hills annually, underrepresented groups in higher education, and the general student population. Outreach through the South Dakota School of Mines and Technology, the SDSTA, and near-by tribal colleges, is becoming deep and substantive. Local citizens will have a special role. There exists in the Lead area a body of knowledge about the Homestake mine that will never be equaled, i.e., the many people who have spent a good part of their lives working in the mine. A team of retired Homestake miners will be a key part of the project, to help make the design and planning optimal, realistic and safe. There are many technical implications of the observatory beyond direct imaging of rock behavior, such as: (1) Underground and Mine Safety - more quantitative methods to quickly locate potential dynamic rock failure within the mine will be an immediate benefit, (2) Homeland Security of Underground Facilities - use reciprocity to derive methods to detect and characterize underground structures and activity, and study explosions associated with coal mining activity in Wyoming as contribution to nuclear monitoring, and (3) Global Seismology - take advantage of location and depth of array to assess maximum frequency content of teleseismic phases.

知识分子的优点：“地理是深地球。”尽管科学家可以对深空和恒星的形成形象，但目前不存在即使在地球上成像数十米的工具。 所需的是哈勃望远镜进入地球的望远镜，而不是远离地球的工具。 通过该奖项，地下成像和传感团队将在南达科他州的HomeStake Mine的深层科学和工程实验室（Dusel）设施中开发，结合​​和完善对地球进行成像所需的科学，以使用这些能力来获得对岩石和岩体的了解，并将这些发现用于工程工具。 团队使用的所有地球询问方法都在很大程度上依赖于反转方法，因为收集的数据不能直接测量关注的物理量。 提出的实验套件结合了许多方法的力量，以在必要的反转上提供强大的限制，并将图像引入更加焦点。 Homestake矿山提供了独特的设施，该设施允许进行多个尺度和多物理运动。在研究开始之前，项目团队将针对所需的基础架构和安全程序开发详细的设计。 基础架构只是大型dusel企业的一小部分，需要完整的工作故障结构文件。 将举办几个研讨会，为了扩大项目团队的参与，并涉及更多社区参与Dusel企业，以及在Homestake矿场举行的三场研讨会/设计会议，以提供整体设计过程的真实细节和确保。 Building on the initial contacts made by the PI for his ongoing NSF-supported project at DUSEL, "Towards a Transparent Earth," the observatory, through the Sanford Science and Education Center, will provide a lifelong learning experience for all stakeholders - K-12 students and teachers, the hundreds of thousands of visitors passing through the Black Hills annually, underrepresented groups in higher education, and the general student population. 通过南达科他州矿业和技术学院，SDSTA和近部部落学院的外展活动变得深刻而实质性。 当地公民将发挥特殊作用。 领先地区存在着关于寄宿矿的知识，这些知识将永远不会平等，即，在矿山工作的许多人都花了很多时间。 一组退休的寄宿矿工团队将是该项目的关键部分，以帮助设计和计划最佳，现实和安全。 There are many technical implications of the observatory beyond direct imaging of rock behavior, such as: (1) Underground and Mine Safety - more quantitative methods to quickly locate potential dynamic rock failure within the mine will be an immediate benefit, (2) Homeland Security of Underground Facilities - use reciprocity to derive methods to detect and characterize underground structures and activity, and study explosions associated with coal mining activity in Wyoming as contribution to nuclear monitoring, and （3）全球地震学 - 利用阵列的位置和深度来评估伸展震荡阶段的最大频率含量。
