GeoTraverse: A Geologic Framework for USArray - workshop

拟议的GeoTraverse研讨会的目的是探索一种基于地质的方案，如何设计和协调美国连续海岸到海岸的高分辨率覆盖。GeoTraverse的主要动机是迫切需要将地质数据系统地整合到EarthScope计划中。此外，我们认为地质学界的广泛参与和公众的认可对地球观测的最终成功至关重要。在EarthScope产品中，所有区域性EarthScope研究的总体综合，例如由一个或多个地质样带提供，对于定义和理解北美大陆的结构和演化至关重要。目前部署USArray的困难在于，这种布置不能提供足够的地壳空间分辨率，而这是必不可少的地质分析。因此，研讨会将主要关注USArray柔性地震阵的地质相关和合理使用，利用被动和主动震源地震学。GeoTraverse设想的地球物理和地质数据的结合在科学上是综合的和综合的，并将优化公众利益和推广。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2006年1月在美国的一个中心地点召开会议。一系列的介绍性演讲将提供背景和技术限制。随后的分组将探讨区域和专题目标，随后是对GeoTraverse提案的全体讨论。将有两名负责组织事务的首席召集人和一个代表美国大陆地质地区和主题的科学家指导小组。指导小组将从申请和邀请中挑选参与者。

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.
