Collaborative Research: Geologic, Tectonic, and Geodynamic Processes of the Eastern North American (ENAM) Passive Margin Workshop

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社区，他们研究形成大陆、开阔的海洋盆地、侵蚀、运输和沉积沉积物的过程，以及相关的自然灾害，如地震、海啸、海平面上升和陆地和水下的山体滑坡。地球科学主要是在陆地上完成的，但并不完全是在陆地上进行的，涉及到一大批可移动的地震仪，这些仪器能够俯瞰地壳和地幔，从而组装出美国地质基础的图像。GeoPRISMS的研究主要是在海洋中进行的，但不只是在海洋中，特别是在该国周围的沿海地区。它包括能够对保存在沿海水域下的沉积包进行成像和取样的设施和仪器。总体而言，EarthScope和GeoPRISMS的研究跨越海岸线，在这样做的过程中，不仅为了解自然灾害，而且为了解国家的自然资源，包括传统和替代能源，提供了一个综合框架。我们的项目是举办两个研讨会，面向对美国东海岸岩石圈形成、裂谷启动、被动边缘演化以及与动态地幔和地表过程相互作用感兴趣的更广泛的地球范围和GeoPRISMS研究社区。美国东部包括阿巴拉契亚山脉和典型的大西洋被动边缘，因此是与大陆组装、造山、大陆裂谷和裂谷后被动边缘演化有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例是以这一地理区域的数据和研究为基础的。一个小型的规划研讨会将在德克萨斯州的奥斯汀举行，以配合2011年5月的地球范围会议。科学研讨会将于2011年秋季在利哈伊大学举行。我们的目标是将社区努力集中在跨学科学习和方法上，目标是一个由来自大学、国家实验室、联邦和州机构的科学家组成的全国和国际论坛，包括职业生涯早期的科学家和研究生。可运输的EarthScope阵列将于2012-13年抵达美国东部，GeoPRISMS已将该地区确定为了解大陆裂谷启动和演化过程的关键地点。因此，现在是组织这两个社区并确定关键科学目标的最佳时机。我们设想这些研讨会将在随后的科学提案提交过程中作为一个自我组织的论坛。

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.
