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, and integrates the co-production of knowledge. This award fulfills part of that aim.This project will bring together earth system scientists, engineers, ecologists, and anthropologists to develop a plan to document and explain changes in ecosystems and their effects on the plants, animals, indigenous peoples, and industrial infrastructure of the Arctic region. It will emphasize interactions between these elements to help understand, inform, and plan for changes to come. Researchers will focus on the Yamal Peninsula, which presents a continuous gradation of habitat types from forest in the south to tundra in the north, a rich diversity of endemic and invasive plant and animal species, a large population of traditional peoples, and economically critical natural resources. Yamal serves as a small-scale and manageable model for the Arctic as a whole, wherein changes in climate and their effects on temperature, precipitation, landform, plants, animals, peoples, and infrastructure need to be understood and related to one another. The project will contribute to the curriculum development for a collaborative, transdisciplinary online inter-institutional undergraduate and graduate course to train the next generation of scientists to take a holistic approach to problem solving. The team will directly engage Indigenous knowledge holders and other stakeholders throughout the research project. The project aims at developing a convergence research team to study the Yamal region as an ideal natural laboratory for transdisciplinary work to understand the complexity and adaptation of Arctic biotic and abiotic systems to climate change, and the feed-forward and feedback mechanisms modulating the co-evolution of human society and natural systems. The participants will focus on developing research ideas and approaches for testing the hypothesis that displacing Arctic systems from their historic state of dynamic equilibrium under changing environment stimulates further changes to abiotic, biotic, and socio-cultural elements, particularly when combined with the spread of industrial infrastructure, to increase the role of feed-forward and feedback mechanisms. Two transdisciplinary research "transects" will be considered as main determinants of the Arctic system with two contrasting scenarios: gradual warning and extreme weather events. Planned activities will include two workshops, monthly virtual conferences, international research capacity building, and a synthesis paper.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.

新北极航行（NNA）是NSF的十大创意之一。NNA项目解决快速变化的北极地区的趋同科学挑战。北极研究需要为国家、更大地区和地球仪的经济、安全和复原力提供信息。NNA授权从地方到国际规模的新研究伙伴关系，使下一代北极研究人员多样化，并整合知识的共同生产。该项目将把地球系统科学家、工程师、生态学家和人类学家聚集在一起，制定一项计划，记录和解释生态系统的变化及其对北极地区植物、动物、土著居民和工业基础设施的影响。它将强调这些元素之间的相互作用，以帮助理解，通知和计划即将到来的变化。研究人员将把重点放在亚马尔半岛，它呈现出从南部森林到北部苔原的连续渐变的栖息地类型，丰富多样的特有和入侵植物和动物物种，大量的传统民族人口，以及经济上至关重要的自然资源。亚马尔是整个北极的一个小规模和可管理的模型，其中气候变化及其对温度，降水，地形，植物，动物，人民和基础设施的影响需要相互理解和联系。 该项目将促进协作、跨学科的在线跨机构本科生和研究生课程的课程开发，以培训下一代科学家采取整体方法解决问题。该小组将在整个研究项目中直接与土著知识持有者和其他利益攸关方接触。 该项目旨在建立一个趋同研究小组，将亚马尔地区作为跨学科工作的理想自然实验室进行研究，以了解北极生物和非生物系统对气候变化的复杂性和适应性，以及调节人类社会和自然系统共同进化的前馈和反馈机制。与会者将侧重于发展研究思路和方法，以检验这一假设，即在不断变化的环境下，将北极系统从其历史动态平衡状态中取代，会刺激非生物、生物和社会文化要素的进一步变化，特别是当与工业基础设施的扩展相结合时，以增加前馈和反馈机制的作用。两个跨学科研究“样带”将被视为北极系统的主要决定因素，并有两种截然不同的情景：逐渐预警和极端天气事件。计划的活动将包括两个研讨会，每月的虚拟会议，国际研究能力建设，和一个综合paper.This奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的知识价值和更广泛的影响审查标准。
