This project will support a two-day workshop at the Lamont Doherty Earth Observatory campus of Columbia University on August 5-6, 2019 in order to synthesize research results from the Aleutian-Alaska Subduction Zone. Participants are drawn from ~ 20 individual projects funded by the NSF-GeoPRISMS Program (Geodynamic Processes at RIfting and Subducting Margins), with a focus on understanding the fundamental processes underlying great earthquakes and other types of fault slip, hazardous volcanic eruptions and the building of the continental crust. Approximately 50 participants will gather at Lamont for the purposes of sharing and synthesizing results across disciplines and across the subduction zone, from the incoming plate through the megathrust to the volcanic arc. Over 35% of the participants will be early-career scientists or graduate students who will be engaged in formal and informal discussions to develop a lasting network. The primary workshop output will be publications, including synthesis papers, that will integrate GeoPRISMS science. The other primary output will be the scientific connections made between individual projects that would not otherwise happen, essential to realizing the value of the focus site approach within GeoPRISMS.The Alaska-Aleutian Margin is one of the focus sites for the GeoPRISMS Subduction Cycles and Deformation Initiative. It was chosen as an ideal location to study arc volcanism, development of continental crust, and earthquake processes over the seismic cycle. GeoPRISMS-NSF projects funded since FY12 span topics ranging from deformation in the megathrust to plutonic building blocks of continents to volatile cycling from slab to surface. Approaches include laboratory deformation experiments and geochemical analyses, and novel field deployments using portable mass spectrometers, seafloor strain sensors, and the Alaska Amphibious Array. This synthesis workshop is necessary to share initial findings, make cross-project connections, and integrate results from the Alaska-Aleutian focus site. Workshop participants will engage deeply in multi-disciplinary discussions (including geophysics, geochemistry, experimental and theoretical approaches). All presentations and discussions will be plenary to entrain everyone in the issues, results and controversies of each science topic and approach.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将于2019年8月5日至6日在哥伦比亚大学拉蒙多尔蒂地球观测站校园举办为期两天的研讨会，以综合阿留申-阿拉斯加俯冲带的研究成果。参与者来自NSF-GeoPRISMS计划（裂谷和俯冲边缘的地球动力学过程）资助的约20个项目，重点是了解大地震和其他类型断层滑动，危险火山爆发和大陆地壳建设的基本过程。 大约50名与会者将聚集在拉蒙，目的是分享和综合跨学科和整个俯冲带的结果，从传入板块到巨型逆冲断层到火山弧。 超过35%的参与者将是早期职业科学家或研究生，他们将参与正式和非正式的讨论，以建立持久的网络。讲习班的主要产出将是将纳入地球同步卫星信息系统科学的出版物，包括综合论文。另一项主要产出将是在各个项目之间建立科学联系，否则这些联系是不会发生的，这对实现GeoPRISMS内重点地点方法的价值至关重要。它被选为研究弧火山作用、大陆地壳发展和地震周期中地震过程的理想地点。GeoPRISMS-NSF自2012财年以来资助的项目涵盖了从巨型逆冲断层的变形到大陆的深成构造块，再到从板块到地表的挥发性循环等主题。 方法包括实验室变形实验和地球化学分析，以及使用便携式质谱仪，海底应变传感器和阿拉斯加两栖阵列的新的现场部署。这个综合研讨会是必要的，以分享初步研究结果，使跨项目的连接，并整合阿拉斯加-阿留申重点网站的结果。讲习班参与者将深入参与多学科讨论（包括地球物理学、地球化学、实验和理论方法）。所有的演讲和讨论都将是全体会议，以吸引每个人参与每个科学主题和方法的问题，结果和争议。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
