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 environments, and the built environment in the following NNA focus areas: Arctic Residents, Data and Observations, Forecasting, and Global Impact.Fjords are long narrow inlets that connect glacier-covered land to the ocean. The release of meltwater and sediments from the glaciers makes these waters nutrient rich. These conditions support healthy marine ecosystems with high densities of seabirds, marine mammals, and fishes. As a result, many Arctic settlements whose livelihoods depend on fishing and hunting are located near glacial fjords. Arctic warming is driving the retreat of glaciers, resulting in a warming of the ocean waters that has decreases the prosperity of fjord ecosystems. In addition, human activities such as commercial fishing, resource extraction, and tourism increasingly influence coastal regions. Research on changes in Arctic coastal margins has focused primarily on the impact of changing ice sheets, with comparatively less emphasis on the surrounding fjord systems. Fewer studies still seek to integrate the impacts of changing natural and social systems on fjords. The goal of this project is to understand how the combined impact of these changes affect the greater fjord system comprised of the ice, the fjords, the marine ecosystem, and the local communities that rely on them for their livelihood. This goal will be achieved through a detailed study of physical, biological, and social system interactions in Greenland fjords by an interdisciplinary team of oceanographers, glaciologists, climate scientists, environmental historians, fisheries, and ecosystem experts. The focus of this study will be on two different fjords in Greenland to understand how their unique characteristics influence the ice-fjord-marine life-local people system. Information will be disseminated to US and Greenlandic governments, communities, and other stakeholders to develop adaptive strategies to sustain fjord systems in a changing Arctic.The goal of this project is to improve understanding of the physical and biological processes that sustain ecosystems in glacial fjords. This will be achieved through an integrated analysis of historical data, collection of new data, and model projections. Specific research activities include: i) sampling cruises to two fjords in Greenland to obtain physical, biological, and chemical oceanographic measurements; ii) ocean mooring to measure the seasonal variability of these systems; iii) collection of fish eggs and larvae for measurement and modeling of transport in fjord systems using particle tracking models; iv) remote sensing and regional-scale modeling to assess glacier changes in the fjords; v) use of climate and ice sheet models to derive future projections; and vi) collation and analysis of local societal histories through archival and on-site research with Greenlandic partners. Results will be integrated into a detailed comparative analysis of the climatic, ecosystem, and societal forces influencing ecosystem sustainability at the local and national level. The collaboration between US and Greenlandic researchers will benefit society by generating information that can be used to help develop adaptive strategies and sustainable practices. Additional benefits to society result from the training of undergraduate and graduate students, and a postgraduate fellow Results will be results will be shared not only through university teaching and academic publishing but also with the broader public in the USA and Greenland through plain-language publications, new websites, a film and other multimedia productions, public lectures, and new international partnerships.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、安全和恢复力提供信息。 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、数据和观测、预测和全球影响。峡湾是连接冰川的狭长入口。覆盖陆地到海洋。冰川融水和沉积物的释放使这些水域营养丰富。这些条件支持健康的海洋生态系统，拥有高密度的海鸟、海洋哺乳动物和鱼类。因此，许多以捕鱼和狩猎为生的北极定居点位于冰川峡湾附近。北极变暖正在推动冰川退缩，导致海水变暖，从而降低了峡湾生态系统的繁荣。此外，商业捕鱼、资源开采和旅游业等人类活动日益影响沿海地区。对北极海岸边缘变化的研究主要集中在冰盖变化的影响上，相对较少地关注周围的峡湾系统。很少有研究仍在寻求整合自然和社会系统变化对峡湾的影响。该项目的目标是了解这些变化的综合影响如何影响由冰、峡湾、海洋生态系统以及依赖它们谋生的当地社区组成的更大的峡湾系统。这一目标将通过由海洋学家、冰川学家、气候科学家、环境历史学家、渔业和生态系统专家组成的跨学科团队对格陵兰峡湾的物理、生物和社会系统相互作用进行详细研究来实现。这项研究的重点将是格陵兰岛的两个不同峡湾，以了解它们的独特特征如何影响冰-峡湾-海洋生物-当地人系统。信息将传播给美国和格陵兰岛政府、社区和其他利益相关者，以制定适应性战略，以维持不断变化的北极地区的峡湾系统。该项目的目标是提高对维持冰川峡湾生态系统的物理和生物过程的了解。这将通过历史数据的综合分析、新数据的收集和模型预测来实现。具体研究活动包括： i) 对格陵兰岛两个峡湾的航行进行采样，以获得物理、生物和化学海洋学测量结果； ii) 海洋系泊以测量这些系统的季节变化； iii) 收集鱼卵和幼鱼，使用粒子跟踪模型对峡湾系统中的运输进行测量和建模； iv) 用于评估峡湾冰川变化的遥感和区域尺度建模； v) 使用气候和冰盖模型来得出未来预测； vi) 通过与格陵兰合作伙伴进行档案和现场研究来整理和分析当地社会历史。结果将被纳入对影响地方和国家层面生态系统可持续性的气候、生态系统和社会力量的详细比较分析中。美国和格陵兰研究人员之间的合作将通过生成可用于帮助制定适应性战略和可持续实践的信息来造福社会。本科生和研究生以及研究生的培训会给社会带来额外的好处。结果将不仅通过大学教学和学术出版来分享，而且还通过通俗易懂的语言出版物与美国和格陵兰岛的更广泛公众分享，新网站、电影和其他多媒体作品、公开讲座以及新的国际合作伙伴关系。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，被认为值得支持。
