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 and Resilient Infrastructure.Climate change poses a major threat to the water security of Alaska Native communities. While local, state, and federal agencies have spent considerable funds to design and build piped water supply systems in rural Alaskan communities, many of these systems were built on permafrost soils assuming the ground would remain frozen year-round. Now, rising temperatures are causing arctic permafrost to thaw, which in turn is causing underground water supply pipes to burst and leak. These pipe bursts have led to persistent water supply outages, to the extent that nearly 80% of interviewed Alaska Native residents cite pipe leaks or breaks as one of the most pressing issues affecting their quality of life. New sensing technologies have the potential to mitigate water supply problems by enabling operators to pre-emptively detect leaks and prevent outages. At the same time, water system designs need to be mindful of the cultural meaning assigned to these systems and fully include Alaska Native communities in their co-design. Integrating new technologies requires a coordinated approach that recognizes traditional and local knowledge and empowers Alaska Native communities in the infrastructure design process. Towards this goal, this project bridges the environmental, technological, and social challenges that Alaska Native communities face with regard to their water systems. The project team will work closely with Alaska Native communities to co-develop new climate-resilient water infrastructure through knowledge co-production, the deployment of novel real-time water supply monitoring systems, and characterization of Arctic soil conditions and their effects on pipeline structural integrity.To develop climate-resilient water supply systems for Alaska Native communities, this research project will bring together a multidisciplinary research team of engineers and social scientists working in coordination with village residents, tribal council leaders, utility staff, and nonprofit organizations representing Alaska Native communities in the Norton Sound region of western Alaska. Using a convergent research approach, this project will address fundamental knowledge gaps at the intersection of social, engineered and natural systems. First, knowledge co-production methods will be applied to understand the cultural significance of water and identify community-specific perspectives that affect the engineering design process. Second, a novel wireless sensor network for water supply monitoring will be deployed and paired with multiclass data-driven and model-based leak detection techniques to understand their potential for mitigating real-world water supply disruptions. Finally, lab and field experiments on Arctic soils will be combined with data-driven models to characterize the long-term performance of soil foundations and predict the potential for future soil-induced damage to water systems. These research objectives will be complemented by outreach efforts aimed at training community members in the use of sensing equipment, as well as educational programs designed to raise awareness of water supply issues and social disparities facing Alaska Native communities.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.

航行新北极 (NNA) 是 NSF 的 10 大创意之一。 NNA 项目解决快速变化的北极地区的融合科学挑战。这项北极研究需要为国家、更大地区和全球的经济、安全和复原力提供信息。 NNA 授权从地方到国际范围内的新研究伙伴关系，使下一代北极研究人员多样化，加强正规和非正规教育的努力，并在适当的情况下整合知识的共同生产。该奖项通过解决以下 NNA 重点领域中社会系统、自然环境和建筑环境之间的相互作用来实现该目标的一部分：北极居民和弹性基础设施。气候变化对阿拉斯加原住民社区的水安全构成了重大威胁。虽然地方、州和联邦机构花费了大量资金在阿拉斯加农村社区设计和建造管道供水系统，但其中许多系统都是建立在永久冻土上的，假设地面全年保持冰冻。现在，气温上升导致北极永久冻土融化，进而导致地下水供应管道破裂和泄漏。这些管道爆裂导致持续供水中断，近 80% 的受访阿拉斯加原住民居民将管道泄漏或破裂视为影响他们生活质量的最紧迫问题之一。新的传感技术使操作员能够预先检测泄漏并防止停电，从而有可能缓解供水问题。与此同时，供水系统设计需要注意赋予这些系统的文化意义，并在其协同设计中充分纳入阿拉斯加原住民社区。整合新技术需要采取协调一致的方法，承认传统和当地知识，并在基础设施设计过程中赋予阿拉斯加原住民社区权力。为了实现这一目标，该项目弥合了阿拉斯加原住民社区在供水系统方面面临的环境、技术和社会挑战。该项目团队将与阿拉斯加原住民社区密切合作，通过知识合作、部署新型实时供水监测系统以及描述北极土壤条件及其对管道结构的影响，共同开发新的气候适应型水基础设施为了为阿拉斯加原住民社区开发适应气候变化的供水系统，该研究项目将汇集一个由工程师和社会科学家组成的多学科研究团队，与村庄居民、部落理事会领导人、公用事业工作人员和代表阿拉斯加原住民的非营利组织合作的社区阿拉斯加西部的诺顿湾地区。该项目将采用融合研究方法，解决社会、工程和自然系统交叉点的基本知识差距。首先，将应用知识共同生产方法来理解水的文化意义，并确定影响工程设计过程的社区特定观点。其次，将部署用于供水监测的新型无线传感器网络，并将其与多类数据驱动和基于模型的泄漏检测技术配合使用，以了解其缓解现实世界供水中断的潜力。最后，北极土壤的实验室和现场实验将与数据驱动模型相结合，以表征土壤基础的长期性能，并预测未来土壤对水系统造成损害的可能性。这些研究目标将辅之以旨在培训社区成员使用传感设备的外展工作，以及旨在提高对阿拉斯加原住民社区面临的供水问题和社会差异的认识的教育计划。该奖项反映了 NSF 的法定使命，并具有通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
