Proposal for EarthScope Pre-meeting Workshop Support: Leveraging USArray - Opportunities for Onshore/Offshore Experiments and USArray and EarthScope Science in Alaska

EarthScope会前研讨会支持：“利用USAray：陆上/海上实验的机会“研讨会组织者：Dayanthie S. Weeraratne（加州州立大学，北岭）Trehu（俄勒冈州州立大学）“阿拉斯加的USAray和EarthScope科学“研讨会组织者：Jeff Freymueller和Doug Christensen（都在阿拉斯加大学费尔班克斯）2009年EarthScope全国会议之前的两个会前研讨会的重点是“利用USAray：陆上/海上实验的机会”和“阿拉斯加的USAray和EarthScope科学”。“这些研讨会分别于2009年5月12日上午和下午举行，研讨会报告将张贴在地球观测网站上。 上午的研讨会讨论了海上地震仪器对实现北美边缘Earthscope目标的潜在贡献。其目的是确定在北美大陆边缘可以专门解决的科学目标，并讨论实现这些目标所需的仪器。下午的研讨会侧重于阿拉斯加的EarthScope科学目标，为USAray抵达阿拉斯加做准备。 其目标包括更新和完善阿拉斯加EarthScope的科学目标，为新的跨学科合作提供种子，并为IRIS提供信息，以便根据科学需求为USAray部署的后勤和运营决策提供信息。这两个讲习班之间有很强的协同作用，因为阿拉斯加是陆上/近海小组的三个目标区域之一，任何关于阿拉斯加沿海地区科学目标的讨论都应考虑近海数据如何有潜力促进实现科学目标。这一协同作用反映在参加这两个讲习班的与会者中。

EarthScope Pre-meeting Workshop Support: "Leveraging USArray: Opportunities for Onshore/Offshore Experiments"Workshop Organizers: Dayanthie S. Weeraratne (California State University, Northridge) Anne M. Trehu (Oregon State University)"USArray and EarthScope Science in Alaska"Workshop Organizers: Jeff Freymueller and Doug Christensen (both at University of Alaska Fairbanks)Two pre-meeting workshops prior to the 2009 EarthScope National Meeting are focused on "Leveraging USArray: Opportunities for Onshore/Offshore Experiments" and on "USArray and EarthScope Science in Alaska." These workshops are being held on the morning and afternoon of May 12, 2009, respectively, and workshop reports will be posted on the EarthScope web site. Potential contributions of offshore seismic instrumentation towards achieving Earthscope objectives at the edges of North America are discussed during the morning workshop. The objectives are to identify scientific goals that can be uniquely addressed on the continental margins of North America and discuss instrumentation needs for achieving these goals. The afternoon workshop focuses on EarthScope scientific targets in Alaska, in preparation for the arrival of USArray in Alaska. Among the objectives are to update and refine scientific goals of EarthScope in Alaska, seed new interdisciplinary collaborations and provide information to IRIS so that logistical and operational decisions for USArray deployment are informed by scientific needs. There is strong synergy between these two workshops as Alaska is one of the three regions targeted by the onshore/offshore group, and any discussion of scientific targets in the coastal regions of Alaska should consider how offshore data have the potential to contribute towards achieving scientific goals. This synergy is reflected in the large fraction of participants attending both workshops.
