2011 EarthScope Workshop: Opportunities for EarthScope Science in Alaska in Anticipation of USArray

EarthScope的科学调查依赖于三个地球物理数据采集设备：圣安地列斯断层观测站、板块边界观测站（PBO）和可移动地震和大地电磁观测站（USArray）。自2004年以来，PBO已经在阿拉斯加建立了业务，而USArray预计将于2014年开始在东海岸部署。未来几年，美国国家科学基金会的其他项目将支持阿拉斯加的相关研究工作，特别是地质系统项目。即将在阿拉斯加部署的USArray可移动地震阵列为广泛的科学界提供了一个及时的提示，可以利用EarthScope设施和其他来源的数据来讨论科学机会和目标。在德克萨斯州奥斯汀举办的2011年“地球观测”全国会议上，众多科学家将在研讨会上讨论这些问题和相关话题。与单独举办研讨会相比，此时召开研讨会将以最低的成本吸引大批与会者。研讨会的介绍和讨论将有助于向美国地球科学界通报新的科学机会，并将根据阿拉斯加EarthScope设施未来部署和运行的科学需求提供建议。研讨会的主要产品将包括一份研讨会报告、一份征求所有与会者意见的一页白皮书、一套关于阿拉斯加地球观测设备的建议，以及一个更新的阿拉斯加地球观测科学网站，该网站与所有相关工作，如地质科学和卡斯卡迪亚倡议，都有明确的联系。

EarthScope science investigations depend on the three EarthScope facilities for geophysical data acquisition: San Andreas Fault Observatory at Depth, Plate Boundary Observatory (PBO), and the transportable seismic and magnetotelluric Observatory (USArray). PBO has an established presence in Alaska since 2004, while USArray is anticipated starting in 2014, following its deployment on the East Coast. Other NSF programs will be supporting related research efforts in Alaska in the coming years, in particular the GeoPRISMS program.The coming deployment of the USArray transportable seismic array to Alaska provides a timely prompt for a broad scientific community to discuss scientific opportunities and goals that can be addressed using data from EarthScope facilities and other sources. These and related topics will be discussed by a broad group of scientists at a workshop organized in conjunction with the 2011 EarthScope National Meeting in Austin, Texas. Convening the workshop at this time will draw a large group at a minimal cost, compared to a stand-alone workshop. The workshop presentations and discussions will help inform the US earth science community about new scientific opportunities, and will provide recommendations based on scientific needs about the future deployment and operation of EarthScope facilities in Alaska.The primary products of the workshop will include a workshop report, a of 1-page white papers solicited from all attendees, a set of recommendations for EarthScope facilities in Alaska, and an updated website for EarthScope Science in Alaska, with explicit connections to all related efforts, such as GeoPRISMS and the Cascadia Initiative.
