Conference: Permafrost and Infrastructure Symposium: Merging science, engineering and community-based knowledge

永久冻土和基础设施研讨会将汇集各国和国际北极科学和工程专家，就如何解决永久冻土融化对道路和社区基础设施的影响分享知识。参与者将包括在阿拉斯加北部工作的美国研究人员，他们在北极其他地区拥有专业知识的国际同事，以及来自阿拉斯加北坡的当地专家，包括区域规划师、项目经理和政策制定者。研讨会将在道尔顿高速公路（Dalton Highway）沿线、Utqiaġvik（原Barrow）和Point Lay村举行，让与会者有机会亲眼看到这些问题，并向那些设计、建造、维修和生活在易解冻基础设施中的人学习。该活动的概念基于一种融合研究模式，将科学和工程研究实践与当地知识和优先事项相结合，以制定改善北极基础设施的更好战略。研讨会将产生一份路线图文件，直接解决当地和区域居民和规划者优先考虑的与永久冻土有关的挑战。主要研究结果将提交给当地决策者以及北极科学和政策论坛。永久冻土退化正威胁着住宅、交通和工业基础设施的稳定性，缩短其使用寿命，造成严重的经济困难以及健康和安全危害。随着北极持续变暖，到本世纪中叶，多达70%的极地周边基础设施将面临风险。现在应对这些风险所需的适应速度要求工程师与科学家密切合作，以更好地了解永久冻土融化的预测模型和局部尺度上永久冻土的可变性。通过其融合方法，研讨会将讨论NSF的战略重点，以推进对北极地区正在发生的快速变化的系统级理解，同时通过将科学界开发的知识与工程界的经验以及北极居民和规划者的优先事项联系起来，促进实用的、基于科学的适应方法。来自多个研究永久冻土融化和海岸侵蚀的新北极导航小组的研究人员的参与将加强国家科学基金会项目之间的协同作用，同时减少对地方和区域合作伙伴的外联和参与的需求。该奖项反映了美国国家科学基金会的法定使命，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。

The Permafrost & Infrastructure Symposium will bring together national and international Arctic science and engineering experts to share knowledge on how to address impacts of permafrost thaw on roads and community infrastructure. Participants will include U.S. researchers working in Northern Alaska, their international colleagues with expertise in other parts of the Arctic, and local experts from Alaska’s North Slope, including regional planners, project managers, and policy makers. The symposium will be held in the field—along the Dalton Highway, in Utqiaġvik (formerly Barrow) and the village of Point Lay — giving participants the opportunity to see the issues firsthand and to learn from those who design, build, repair, and live with thaw-susceptible infrastructure. The concept for the event is based on a convergence research model to pair scientific and engineering research practices with local knowledge and priorities to develop better strategies for improving Arctic infrastructure. The symposium will result in a roadmap document that directly addresses the permafrost-related challenges prioritized by local and regional residents and planners. Key findings will be presented to local policy makers and at Arctic science and policy forums.Permafrost degradation is threatening the stability and shortening the lifespan of residential, transportation and industrial infrastructure, resulting in serious economic hardship and health and safety hazards. With continued Arctic warming, up to 70% of fundamental circumpolar infrastructure will be at risk by mid-century. The rate of adaptation now needed to address these risks requires that engineers work closely with scientists to better understand predictive models of permafrost thaw and the variability of permafrost at local scales. Through its convergence approach, the symposium will address NSF strategic priorities for advancing a systems-level understanding of the rapid changes occurring in the Arctic, while fostering practical, science-based approaches to adaptation by linking the knowledge developed by the science community with the experience of the engineering community and the priorities of Arctic residents and planners. The participation of researchers from multiple Navigating the New Arctic teams studying permafrost thaw and coastal erosion will enhance synergies between NSF projects while reducing the demands of outreach and engagement on local and regional partners.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.
