Earthscope and GeoPRISMS represents research communities of geologists, geophysicists, and geodynamicists who study the processes that build continents, open ocean basins, erode, transport and deposit sediment, and the associated natural hazards of earthquakes, tsunamis, sea level rise, and landslides both on land and under water. Earthscope science is done primarily, but not exclusively on land and involves a large transportable array of seismometers that are able to look down into the crust and mantle in assembling an image of the geologic foundation of the United States. GeoPRISMS research is done primarily, but not exclusively in the ocean, specifically in the coastal regions surrounding the country. It includes facilities and instruments able to image and sample the sedimentary packages preserved beneath coastal waters. Collectively, Earthscope and GeoPRISMS research spans the coastline and in doing so, provides an integrated framework for understanding not only natural hazards, but also the nation's natural resources including traditional and alternative sources of energy. Our project is to convene two workshops open to the broader Earthscope and GeoPRISMS research communities interested in the processes of lithospheric formation, rift initiation, passive margin evolution, and interactions with dynamic mantle and surface processes for the east coast of the United States. The eastern United States encompasses the Appalachian Mountains and the archetype Atlantic passive margin and as a result is a source of formative thinking related to continental assembly, mountain building, continental rifting, and post-rift passive margin evolution. Key paradigms such as the Wilson cycle and global sea level change are based on data and research in this geographic area. A small planning workshop is to be held in Austin, TX in concert with the May, 2011 EarthScope meeting. The science workshop is to be held at Lehigh University in the Fall, 2011. Our goal is to focus community effort on cross-discipline learning and approaches, targeting a national and international forum of scientists from universities, national labs, federal, and state agencies including early-career scientists and graduate students. The transportable array of EarthScope arrives in the eastern United States in 2012-13 and GeoPRISMS has identified the same region as a key place to understand the processes of continental rift-initiation and evolution. Therefore, the timing is now perfect to organize both communities and identify the crucial science targets. We envision the workshops to serve as a forum for self-organization in the subsequent science proposal submission process.

Earthscope 和 GeoPRISMS 代表地质学家、地球物理学家和地球动力学家的研究团体，他们研究大陆、开放洋盆地、侵蚀、运输和沉积沉积物的形成过程，以及地震、海啸、海平面上升和山体滑坡等相关自然灾害。陆地和水下。 地球观测科学主要（但并非完全）在陆地上进行，涉及大量可移动的地震仪阵列，这些地震仪能够俯视地壳和地幔，从而组合出美国地质基础的图像。 GeoPRISMS 研究主要（但不限于）海洋中进行，特别是在该国周边的沿海地区。 它包括能够对沿海水域下保存的沉积物包进行成像和采样的设施和仪器。 总的来说，Earthscope 和 GeoPRISMS 的研究跨越了海岸线，从而提供了一个综合框架，不仅可以了解自然灾害，还可以了解国家的自然资源，包括传统和替代能源。 我们的项目是召开两个研讨会，向更广泛的 Earthscope 和 GeoPRISMS 研究界开放，这些研究界对美国东海岸的岩石圈形成过程、裂谷起始、被动边缘演化以及与动态地幔和表面过程的相互作用感兴趣。 美国东部包括阿巴拉契亚山脉和典型的大西洋被动边缘，因此是与大陆聚合、造山、大陆裂谷和裂谷后被动边缘演化相关的形成性思维的来源。 威尔逊循环和全球海平面变化等关键范式都是基于该地理区域的数据和研究。 与 2011 年 5 月 EarthScope 会议同时举行的小型规划研讨会将在德克萨斯州奥斯汀举行。科学研讨会将于 2011 年秋季在理海大学举行。我们的目标是将社区的努力集中在跨学科学习和方法上，面向来自大学、国家实验室、联邦和州机构的科学家的国内和国际论坛包括职业生涯早期的科学家和研究生。 EarthScope 的可移动阵列于 2012-13 年抵达美国东部，GeoPRISMS 已将同一地区确定为了解大陆裂谷起始和演化过程的关键地点。 因此，现在正是组织这两个社区并确定关键科学目标的最佳时机。我们设想研讨会将作为后续科学提案提交过程中自组织的论坛。
