Plate Boundary Structure and Deformation Workshop

该项目将支持在夏威夷大学马诺阿举办的为期两天的有关板块边界结构和裂谷和俯冲带变形的讲习班。研讨会的主要目标是展示和综合由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撑收敛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UH Manoa的现场研讨会，其中至少23名将是职业生涯早期的科学家(学生、博士后、10年内的终身教职前教师)。该计划将包括主题演讲、海报和照明演讲，以交流参与者进行的活跃科学的广度，以及讨论和早期职业发展的机会。还将举行为期半天的研讨会前会议，面向职业生涯早期的科学家。其目的是让代表所有五个GeoPRISMS重点站点的跨学科科学家小组参与进来，以鼓励新的合作。为便利综合研究成果和解决遗留目标的数据问题，将要求所有参与者开放其GeoPRISMS数据集，并提供指示其位置的DOI；这些数据集将被编目和共享。研讨会组织者将使用蒙大拿州立大学的专业视频服务来制作约1分钟的外展视频，捕捉GeoPRISMS计划的科学发现；这些视频和主旨演讲将在YouTube上提供。对板块构造理论的进一步理解取决于对作用于收敛和发散板块边界的构造过程的调查。总的来说，这些板块边界主要平衡了地球的岩石循环，塑造了我们的地球。研讨会的目的是让一群科学家聚集在一起，强调通过NSF GeoPRISMS资助的项目确定的发现，这些项目包括裂谷启动和演化(RIE)和俯冲旋回和变形(SCD)倡议。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悬而未决的问题：(1)断裂带流变性和变形之间的关系以及它们在野外和实验室中如何在一系列时间和空间尺度上受到约束？(2)地壳和地幔的流变性如何影响和/或记录板块边界的变形？(3)更大规模的岩石圈过程、断裂带流变学和地表过程之间存在哪些反馈？研讨会将促进交叉研究专门知识(例如，地球化学、地质学、地球动力学、地震学、大地测量学、EM等)的跨学科互动。通过鼓励所有参与者的积极参与，解决与基本构造过程有关的问题，并激励未来的研究合作。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，认为值得支持。

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.
