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特·多尔蒂（Lamont Doherty）地球校园举行为期两天的研讨会，以便合成阿留申 - 阿拉斯加（Alaska）俯冲区的研究结果。参与者来自约20个由NSF-Geprisms计划资助的个人项目（裂谷和俯冲边缘的地球动力学过程），重点是理解大地震和其他类型的断层滑移，危险的火山爆发以及大陆甲壳的建筑物的基本过程。 大约有50名参与者将聚集在拉蒙特（Lamont），以共享和综合跨学科和俯冲带的结果，从传入的板到巨型弧线到火山弧。 超过35％的参与者将是早期的科学家或研究生，他们将进行正式和非正式的讨论以开发持久的网络。主要的研讨会输出将是包括综合论文在内的出版物，这些出版物将整合地质科学。另一个主要的产出将是单个项目之间建立的科学联系，而这些连接原本不会发生，这对于实现焦点地点方法的价值至关重要。阿拉斯加 - 阿拉斯加 - 亚利特人的利润率是地理位置俯冲周期和变形计划的重点站点之一。它被选为研究弧火山的理想场所，在地震周期内进行了大陆壳的发展以及地震过程。自财产以来，Geoprisms-NSF项目涵盖了从大型的变形到大陆的plutonic构建块，再到从平板到表面的挥发性循环。 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器，海底应变传感器和阿拉斯加两栖阵列的新型现场部署。该合成研讨会对于共享初始发现，建立跨项目连接并整合了阿拉斯加 - 亚利特焦点网站的结果是必要的。研讨会参与者将深入参与多学科讨论（包括地球物理，地球化学，实验和理论方法）。所有演讲和讨论都将是全体人，以吸引每个科学主题和方法的问题，结果和争议。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来支持的。
