GeoTraverse: A Geologic Framework for USArray - workshop

点击翻译按钮获取中文摘要

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.
