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

地球望远镜会议前研讨会支持：“利用美国阵列：陆上/离岸实验的机会”研讨会组织者：戴安西·S·韦拉拉特内(加利福尼亚州立大学北岭分校)Anne M.Trehu(俄勒冈州立大学)“阿拉斯加的美国阵列和地球望远镜科学”研讨会组织者：杰夫·弗莱穆勒和道格·克里斯滕森(均在阿拉斯加费尔班克斯大学)2009年地球范围全国会议之前的两个会议前研讨会，重点是“利用美国阵列：陆地/离岸实验的机会”和“阿拉斯加的美国阵列和地球望远镜科学”。这些讲习班分别于2009年5月12日上午和下午举行，讲习班报告将在EarthScope网站上公布。上午的研讨会讨论了近海地震仪器对实现北美边缘地区的地观目标的潜在贡献。目标是确定可在北美大陆边缘独特解决的科学目标，并讨论实现这些目标的仪器需求。下午的研讨会重点是地球望远镜在阿拉斯加的科学目标，为美国阵列号抵达阿拉斯加做准备。其中的目标是更新和完善阿拉斯加的EarthScope的科学目标，为新的跨学科合作提供种子，并向IRIS提供信息，以便根据科学需求为USArray部署的后勤和业务决策提供信息。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/近海小组瞄准的三个区域之一，任何关于阿拉斯加沿海地区科学目标的讨论都应考虑到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大部分与会者身上。

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.
