This project will support a two-day workshop at the University of Hawaii at Manoa related to plate boundary structure and deformation at rifts and subduction zones. The primary goal of the workshop is to present and synthesize research results that have been funded by the NSF-GeoPRISMS (Geodynamic Processes at Rifting and Subducting Margins) Program related to understanding the tectonic processes that underpin movement at convergent and divergent plate boundaries. Approximately 50 scientists will participate in the workshop onsite at UH Manoa, of which at least 23 will be early-career scientists (student, postdoc, of pre-tenure faculty within 10 years of PhD). The program will consist of keynotes, posters, and lighting talks to communicate the breadth of active science conducted by participants, as well as discussion sessions and opportunities for early career development. There will also be a half-day pre-workshop meeting for early-career scientists. The aim is to have participation from an interdisciplinary group of scientists representing all five GeoPRISMS focus sites to encourage novel collaborations. To facilitate synthesizing research results and address data legacy targets, all participants will be required to make their GeoPRISMS datasets open-access and provide a doi indicating their location; these will be cataloged and shared. The workshop organizers will employ specialized video services from Montana State University to create ~ 1 minute outreach videos that capture scientific discoveries of the GeoPRISMS program; these and the keynote talks will be made available on YouTube.Advancing understanding of plate tectonic theory hinges on investigations of tectonic processes acting at both convergent and divergent plate boundaries. Together, these plate boundaries primarily balance Earth’s rock cycle and shape our planet. The workshop aims to bring a group of scientists together to highlight discoveries determined through NSF GeoPRISMS funded projects encompassing both the Rift Initiation and Evolution (RIE) and Subduction Cycles and Deformation (SCD) initiatives. The workshop will primarily tackle three outstanding questions associated with plate boundary structure and deformation processes: (1) What are the relationships between fault zone rheology and deformation and how are they constrained across a range of temporal and spatial scales in the field and lab? (2) How does the rheology of the crust and mantle influence and/or record deformation at plate boundaries? (3) What feedbacks exist between larger scale lithospheric processes, fault zone rheology, and surface processes? The workshop will facilitate interdisciplinary interactions that cross-cut research expertise (e.g. geochemistry, geology, geodynamics, seismology, geodesy, EM, etc.) and study locations (i.e. encompassing all GeoPRISMS focus sites) to address questions pertaining to fundamental tectonic processes and motivate future research collaborations by encouraging active participation from all participants.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.

该项目将支助在马诺阿的夏威夷大学举办的一个为期两天的讲习班，讨论板块边界结构和裂谷及俯冲带的变形问题。研讨会的主要目标是介绍和综合由NSF-GeoPRISMS（裂谷和俯冲边缘的地球动力学过程）计划资助的研究成果，这些研究成果与理解支持会聚和发散板块边界运动的构造过程有关。大约50名科学家将参加在UH马诺阿现场研讨会，其中至少23人将是职业生涯早期的科学家（学生，博士后，10年内的终身教职）。该计划将包括主题演讲，海报和照明讲座，以传达参与者进行的活跃科学的广度，以及讨论会和早期职业发展的机会。还将为早期职业科学家举办为期半天的研讨会前会议。目的是让代表GeoPRISMS所有五个重点地点的跨学科科学家小组参与，以鼓励新的合作。为便于综合研究结果和解决数据遗留目标，将要求所有参与者开放其GeoPRISMS数据集，并提供一个表明其位置的数字索引;这些数据集将被编目和共享。研讨会组织者将聘请蒙大拿州立大学的专业视频服务，制作约1分钟的宣传视频，捕捉GeoPRISMS项目的科学发现;这些和主题演讲将在YouTube上提供。推进板块构造理论的理解取决于对作用于会聚和发散板块边界的构造过程的调查。这些板块边界一起主要平衡地球的岩石循环并塑造我们的星球。该研讨会旨在将一组科学家聚集在一起，突出通过NSF GeoPRISMS资助的项目确定的发现，包括裂谷启动和演化（RIE）和俯冲周期和变形（SCD）倡议。该研讨会将主要解决与板块边界结构和变形过程相关的三个突出问题：（1）断层带流变学和变形之间的关系是什么，以及它们如何在野外和实验室的时间和空间尺度范围内受到约束？(2)地壳和地幔的流变学如何影响和/或记录板块边界的变形？(3)在大尺度岩石圈过程、断裂带流变学和地表过程之间存在什么样的反馈？讲习班将促进跨学科的互动，交叉研究专长（如地球化学，地质学，地球动力学，地震学，大地测量学，EM等）。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。
