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Geopisms代表地质学家，地球物理学家和地球动力学家的研究社区，他们研究建立大陆，开放海洋盆地，侵蚀，运输和沉积沉积物的过程，以及相关的地震，海啸，海平面，海平面上升和陆地滑坡的自然危害土地和水下。 Earthscope科学主要是在土地上进行的，但不仅是在土地上进行的，并且涉及大量可运输的地震仪，这些地震仪能够俯视地壳和地幔，以组装美国地质基础的形象。地理编号研究主要是在海洋中，特别是在该国周围的沿海地区进行的，但不仅是在海洋中进行的。 它包括能够在沿海水域下保存的沉积包装和采样的设施和仪器。 总体而言，Earthscope和Geopisms的研究涵盖了海岸线，并在此过程中提供了一个综合框架，不仅了解自然危害，而且还理解了国家的自然资源，包括传统和替代能源。 我们的项目是召开两个研讨会，向更广泛的地球和地理选举主义开放研究社区，对岩石圈形成，裂谷的启动，被动边缘演变以及与美国东海岸的动态地幔和地面过程的相互作用感兴趣。 美国东部涵盖了阿巴拉契亚山脉和原型大西洋驱动边缘，因此是与大陆集会，山区建筑，大陆裂谷和裂谷后的被动边缘进化有关的形成思维的来源。 威尔逊周期和全球海平面变化等关键范例基于该地理区域的数据和研究。 在2011年5月的Earthscope会议上，将在德克萨斯州奥斯汀举行一个小规划研讨会。科学研讨会将于2011年秋天在Lehigh University举行。我们的目标是将社区努力集中在跨学科学习和方法上，以来自大学，国家实验室，联邦和州机构的国家和国际科学家的国家和国际论坛为目标包括早期的科学家和研究生。可运输的地球阵列于2012 - 13年到达美国东部，而地质主义已将同一地区确定为了解大陆裂裂和进化过程的关键地点。 因此，现在的时机非常适合组织两个社区并确定关键的科学目标。我们设想研讨会在随后的科学提案提案过程中作为自组织的论坛。
