NNA Research: Collaborative Research: Arctic, Climate, and Earthquakes (ACE): Seismic Resilience and Adaptation of Arctic Infrastructure and Social Systems amid Changing Climate

航行新北极(NNA)是NSF的十大想法之一。NNA项目解决了快速变化的北极地区汇聚的科学挑战。这项北极研究需要为国家、更大区域和全球的经济、安全和韧性提供信息。NNA增强了从地方到国际的新的研究伙伴关系，使下一代北极研究人员多样化，加强正式和非正式教育的努力，并在适当的情况下整合共同创造知识。该奖项通过在以下NNA重点领域解决社会系统、自然环境和建筑环境之间的相互作用来实现这一目标的一部分：北极居民、教育和弹性基础设施。阿拉斯加州和北极许多其他地区地震活跃，每年经历数千次不同级别的地震。鉴于北极地区对地震的脆弱性以及环境和社会变化的加速，必须从自然环境、建筑环境和社会制度的角度评估该区域基础设施对地震事件的复原力，并了解这些变化如何相互作用和影响该区域的防震和应对地震工作。NNA合作研究项目的总体目标是：1)通过地震监测/建模、社区参与和对自然环境、建成环境和社会系统的相关组成部分之间的相互作用进行有针对性的调查，提高对北极变化对该地区未来地震准备和应对的影响的基本了解；以及2)通过为北极社区提供必要的培训和工具来管理未来与地震有关的灾害，包括规划、准备、缓解和恢复，从而提高它们的地震复原力。项目研究和教育活动将包括有针对性的研究、研讨会和劳动力发展，包括培训和指导新汉普郡大学的三名研究生、佐治亚大学的一名研究生和一名本科生、宾夕法尼亚州立大学的一名研究生、阿拉斯加大学费尔班克斯大学的一名研究生和弗吉尼亚大学的一名研究生。这个NNA合作研究项目建立在一项规划拨款和一个研讨会的结果基础上，该研讨会有重要的社区意见，确定了关于新北极面临的地震挑战以及该地区为管理未来与地震相关的灾害而做好准备和恢复能力的六个主要社区关切和高度优先的研究课题。为了应对这些挑战，NNA协作研究项目的首席研究员(PI)建议开展一项围绕四大战略支柱和目标构建的融合研究和教育计划。这项研究的具体目标包括：1)通过监测阿拉斯加的关键基础设施系统，结合离心机物理模拟，模拟和评估永久冻土融化对土壤和建筑/基础设施基础设施的影响，评估北极地面气候驱动变化下的基础设施地震反应；2)通过调查、访谈和参与性测绘讲习班，共同为当地社区发展公平的地震复原力能力；3)通过系统动力学建模、审查地震设计/规划战略以及社区和州一级的气候适应规划，进行地震复原力建模和评估；以及4)通过ACE青年训练营、土著青年STEM研究经验进行外联和教育，以及关于北极地震复原力和适应能力的国际讲习班。该项目的成功完成具有潜在的变革性影响，通过播种和催化研究，在社区参与和土著知识的基础上，可能导致基础科学和工程方面的突破，以应对新北极面临的地震挑战，并改善该地区对未来与地震相关的灾害的准备和反应。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，被认为值得支持。

Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. This Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region, and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems, natural environment, and built environment in the following NNA focus areas: Arctic Residents, Education, and Resilient Infrastructure.The state of Alaska and many other areas of the Arctic are seismically active, experiencing thousands of earthquakes with different magnitudes every year. Given the vulnerability of the Artic to earthquakes and the accelerating environmental and social changes, it is critical to evaluate the resiliency of the region’s infrastructure to seismic events in the context of the natural environment, built environment, and social systems and understand how these changes interact and impact the region’s preparedness and response to earthquakes. The overarching goals of this NNA Collaborative Research project are to: 1) Improve the fundamental understanding of the impact of Arctic changes on the region’s preparedness and response to future earthquakes through seismic monitoring/modeling, community engagement, and targeted investigations of the interactions between the relevant components of the natural environment, built environment, and social systems; and 2) Enhance the seismic resilience of Arctic communities by providing them with the necessary training and tools to manage future earthquake-related disasters including planning, preparedness, mitigation, and recovery. The project research and education activities will include targeted research studies, workshops, and workforce development including the training and mentoring of three graduate students at the University of New Hampshire, one graduate student and an undergraduate student at the University of Georgia, one graduate student at Pennsylvania State University, one graduate student at the University of Alaska Fairbanks, and one graduate student at the University of Virginia.This NNA Collaborative Research project builds upon the results of a planning grant and a workshop with significant community input that identified six major community concerns and high priority research topics regarding the seismic challenges facing the new Arctic and the region’s preparedness and resilience to manage future earthquake-related disasters. To address these challenges, the Principal Investigators (PIs) of this NNA Collaborative Research project propose to carry out a convergent research and education program structured around four strategic pillars and objectives. The specific objectives of the research include 1) Infrastructure seismic response assessment under climate-driven changes of the Arctic ground through the monitoring of key infrastructure systems in Alaska in combination with centrifuge physical modeling to simulate and evaluate the impact of permafrost thawing on soils and building/infrastructure foundations, 2) Co-development of equitable seismic resilience capacities for local communities through surveys, interviews, and participatory mapping workshops, 3) Seismic resilience modeling and assessment through systems dynamics modeling, review of seismic design/planning strategies, and climate adaptation planning at community and state levels, and 4) Outreach and education through ACE youth training camps, STEM research experience for Indigenous youth, and an international workshop on Arctic seismic resilience and adaptation. The successful completion of this project has the potential for transformative impact by seeding and catalyzing research that could lead to breakthroughs in fundamental science and engineering, informed by community participation and Indigenous knowledge, to address seismic challenges facing the new Arctic and improve the region’s preparedness and response to future earthquake-related disasters.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.
