The purpose of the proposed GeoTraverse workshop is to explore a geologically-based schemeon how to design and coordinate high-resolution, coast-to-coast coverage of theconterminous United States.The primary motivation of a GeoTraverse is the great need for systematic integration ofgeologic data into the EarthScope initiative. Additionally, we assert that broadinvolvement by the geologic community and recognition by the general public is essentialfor the ultimate success of EarthScope. Among the EarthScope products, an over-archingsynthesis of all regional EarthScope studies, such as provided by one or more geologictransects, is critical to define and understand the structure and evolution of the NorthAmerican continent. The difficulty with the current deployment of USArray is that thearrangement offers insufficient spatial resolution of the crust, which is essential togeologic analysis. Therefore, the workshop will primarily focus on geologically relevantand reasonable use of the USArray flexible seismic array, utilizing both passive- andactive-source seismology.The combination of geophysical and geologic data envisioned under GeoTraverse isscientifically integrative and synoptic, and would optimize public interest and outreach.A group of 50 or more active scientists will convene at a central location in the US inNovember 2005 or January 2006. A series of introductory presentations will offerbackground and technical constraints. Subsequent break-out groups will explore regionaland topical targets, followed by plenary discussion toward a GeoTraverse proposal.There will be two lead-conveners who are responsible for organizational matters and asteering group of scientists who represents regions and topics in US continental geology.The steering group will select participants from applications and by invitation.

建议的GeoTraverse研讨会的目的是探讨如何设计和协调高分辨率，海岸到海岸的美国接壤的覆盖范围的地质为基础的计划。GeoTraverse的主要动机是非常需要系统地整合地质数据到EarthScope倡议。此外，我们认为，地质界的广泛参与和公众的认可对地球范围的最终成功至关重要。在EarthScope产品中，对所有区域EarthScope研究的全面综合，例如一个或多个地质断面提供的研究，对于确定和了解北美大陆的结构和演变至关重要。目前部署USAray的困难在于这种布置不能提供足够的地壳空间分辨率，而这是地质分析所必需的。因此，研讨会将主要集中在地质相关和合理使用USArray灵活地震阵列，利用被动和主动源地震学。在GeoTraverse下设想的地球物理和地质数据的组合是科学的综合性和概括性的，一个由50名或更多活跃的科学家组成的小组将于2005年11月或2010年12月在美国的一个中心地点召开会议，January 2006.一系列介绍性发言将提供背景和技术限制。随后的分组将探索区域和专题目标，然后进行全体讨论，以制定GeoTraverse提案。将有两名负责组织事项的牵头召集人和一个代表美国大陆地质学区域和主题的科学家小组。指导小组将从申请和邀请中选择参与者。
