Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. The 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, Data and Observation, Education, and Resilient Infrastructure.Arctic communities face many challenges as they grow and develop in the context of a rapidly changing environment. These challenges include coastal erosion, permafrost thaw, and ecosystem change. Arctic cities need to prepare for critical decisions in the future, which traditional scientific approaches alone are unable to address adequately. Instead, an interdisciplinary, community-based approach is necessary. Utqiagvik, the northernmost urban center in Alaska, is facing many of these common challenges and provides a model for other Arctic cities. This project is developing and deploying a network of environmental sensors collecting continuous information over a five-year period in terrestrial and aquatic locations within the community of Utqiagvik. Community members are deeply involved in the planning process for placement of the sensors, ongoing maintenance, and interpretation of the data. The education component of the project is extensive, providing training opportunities for undergraduate students, graduate students, two postdoctoral scholars, and community members in Utqiagvik. The sensor network yields an unprecedented dataset for examining the interactive effects of the natural and built environments. This project is improving the health and economic well-being of Utqiagvik and other North Slope Borough villages in Alaska.This research investigates two essential challenges for the Arctic city of Utqiagvik, Alaska: i) the impacts of existing community infrastructure practices on the surrounding tundra, coastal, and lagoon landscapes within and around the city, and ii) the impacts of a changing environment on the design and future planning of community infrastructure and buildings. The project has four broad objectives. First, community members and scientists are working together to plan and deploy an integrated sensor network in four target areas of the city. Second, environmental data are being used to assess how the infrastructure of the city interacts with the surrounding air, ground, and water. Third, this knowledge is informing management of infrastructure and planning initiatives for Utqiagvik, and is useful for other Arctic communities as well. Finally, the process of co-production of knowledge among researchers and community members is being studied to better understand how these relationships can successfully build and maintain equitable sharing of knowledge and benefits for the residents of Utqiagvik. The ultimate goal of the project is to understand how the natural and built environments interact with social systems in an Arctic city.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。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 重点领域的社会系统、自然环境和建筑环境之间的相互作用来实现这一目标：北极居民、数据和观测、教育和弹性基础设施。北极社区在成长和发展过程中面临着许多挑战在快速变化的环境背景下。这些挑战包括海岸侵蚀、永久冻土融化和生态系统变化。 北极城市需要为未来的关键决策做好准备，仅靠传统的科学方法无法充分解决这些问题。相反，跨学科、基于社区的方法是必要的。乌特恰维克是阿拉斯加最北端的城市中心，面临着许多共同的挑战，并为其他北极城市提供了榜样。该项目正在开发和部署一个环境传感器网络，在五年内收集 Utqiagvik 社区内陆地和水生地点的连续信息。社区成员深入参与传感器放置、持续维护和数据解释的规划过程。该项目的教育部分内容广泛，为乌特恰维克的本科生、研究生、两名博士后学者和社区成员提供培训机会。传感器网络产生了前所未有的数据集，用于检查自然环境和建筑环境的交互影响。该项目正在改善阿拉斯加乌特恰维克和其他北坡自治区村庄的健康和经济福祉。这项研究调查了阿拉斯加北极城市乌特恰维克面临的两个基本挑战：i) 现有社区基础设施实践对周围苔原的影响、城市内部和周围的沿海和泻湖景观，以及 ii) 不断变化的环境对社区基础设施和建筑的设计和未来规划的影响。该项目有四大目标。首先，社区成员和科学家正在共同努力，在城市的四个目标区域规划和部署集成传感器网络。其次，环境数据被用来评估城市基础设施如何与周围的空气、地面和水相互作用。第三，这些知识为乌特恰维克的基础设施管理和规划举措提供了信息，对其他北极社区也很有用。最后，正在研究研究人员和社区成员之间共同生产知识的过程，以更好地了解这些关系如何成功地为乌特恰维克居民建立和维持知识和利益的公平分享。该项目的最终目标是了解北极城市的自然环境和建筑环境如何与社会系统相互作用。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，认为值得支持。
