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.

NSF的10个大创意之一是导航新北极（NNA）。 NNA项目应对北极快速变化的融合科学挑战。需要进行北极研究，以告知国家，较大地区和地球的经济，安全和韧性。 NNA赋予从本地量表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，加强了正规和非正式教育方面的努力，并在适当的情况下整合了知识的共同生产。该奖项通过解决以下NNA焦点领域中的社会系统，自然环境和建筑环境之间的互动来实现该目标的一部分：北极居民，数据和观察，预测和全球影响。Fjords是长期狭窄的入口，可以连接冰川 - 覆盖着海洋的土地。冰川中释放融化和沉积物使这些水富含营养。这些疾病支持具有高密度海鸟，海洋哺乳动物和鱼类的健康海洋生态系统。结果，许多生计取决于捕鱼和狩猎的北极定居点位于冰川峡湾附近。北极变暖正在推动冰川的撤退，导致海水变暖，从而降低了峡湾生态系统的繁荣。此外，人类活动（例如商业捕鱼，资源提取和旅游业）越来越多地影响沿海地区。北极沿海边缘变化的研究主要集中在变化的冰盖的影响上，对周围峡湾系统的重视程度相对较少。更少的研究仍在寻求整合改变自然和社会系统对峡湾的影响。该项目的目的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靠它们生计的当地社区组成的更大的峡湾系统。通过跨学科的海洋学家，冰川科学家，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，生物学和社会系统相互作用进行详细研究，将实现这一目标。这项研究的重点将放在格陵兰岛的两个不同的峡湾上，以了解它们的独特特征如何影响冰峡 - 马拉松生命周期的人类系统。信息将被传播给我们以及格陵兰政府，社区和其他利益相关者，以制定自适应策略以维持北极地区的峡湾系统。该项目的目的是提高对维持冰川峡湾生态系统的物理和生物学过程的了解。这将通过对历史数据，新数据收集和模型预测的整合分析来实现。特定的研究活动包括：i）将巡航给格陵兰岛的两个峡湾进行取样，以获得物理，生物学和化学海洋学测量； ii）海洋系泊，以测量这些系统的季节性变异性； iii）收集鱼卵和幼虫，用于使用粒子跟踪模型在峡湾系统中测量和建模； iv）遥感和区域尺度建模，以评估峡湾的冰川变化； v）使用气候和冰盖模型来得出未来的预测；和vi）通过与格陵兰伙伴的档案和现场研究对当地社会历史进行整理和分析。结果将集成到对影响地方和国家一级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。我们与格陵兰研究人员之间的合作将通过生成可用于帮助制定自适应策略和可持续实践的信息来使社会受益。培训本科生和研究生的培训对社会的额外好处，研究生的成绩将不仅通过大学教学和学术出版，而且还将通过普通语言出版物与更广泛的公众共享。新网站，电影和其他多媒体作品，公开演讲和新的国际合作伙伴关系。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来获得支持的。
