Navigating the New Arctic (NNA): Co-production of shorefast ice knowledge in Uummannaq Bay, Greenland

海岸冰（也称为陆固冰）是附着在海岸线上的海冰。由于海岸冰不随风和海流漂流，因此它是野生动物的重要栖息地，也是北极地区人类生存、粮食生产和运输的平台。随着气候变暖，北极当地的居民报告说，它在今年早些时候分裂，比几十年前更薄。这些环境变化威胁着野生动物和依赖海岸冰层的传统人类活动的可持续性。尽管意义重大，但格陵兰尚未对海岸冰进行全面的多学科评估。因此，该项目旨在了解海岸冰如何应对大气和海洋变暖，以及这些变化如何影响西格陵兰Uummannaq地区当地社区的生计。该项目的成果将改善北极环境变化的机构知识及其相关影响的预测，并加强美国在一个具有潜在全球战略和经济重要性的地区的关系。该项目将通过利用大型卫星遥感数据集，社区监测以及当地和土著知识来共同制作海岸冰知识。首先，将利用从当地居民收集的知识来补充高分辨率光学卫星传感器的观测结果。然后将使用小型多旋翼无人机启动基于社区的监测计划，以记录关键的海岸冰过程（例如形成和破裂）。这两项活动所产生的定量和定性的海岸冰知识将被用来了解不仅是如何海岸冰已经改变，但这些变化如何在Uummannaq地区的个人和社区的问题。乌曼纳克居民和机构参与项目的各个阶段，再加上持续的观察，将为持续的社区支持奠定基础，并使人们能够对快速环境变化造成的复杂社会、文化和经济变化有新的认识。研究结果还将提高当地居民和机构在自然资源治理和管理方面做出知情和嵌入式选择的能力，以及对个人和集体走向理想和可持续未来的选择。该奖项由国际科学工程办公室共同资助。该奖项反映了NSF的法定使命，并被认为值得通过使用&基金会的学术价值和更广泛的影响审查标准。

Shorefast ice (also known as landfast ice) is sea-ice that is attached to the coastline. Since it does not drift with the winds and currents, shorefast ice forms an important habitat for wildlife and a platform for human subsistence food production and transport in the Arctic. As the climate warms, residents local to the Arctic report that it is breaking up earlier in the year and is thinner than it was a few decades ago. These environmental changes threaten the sustainability of wildlife and traditional human activities that depend on shorefast ice. Despite its significance, a comprehensive multidisciplinary assessment of shorefast ice has yet to be made in Greenland. This project therefore seeks to understand how shorefast ice has responded to atmospheric and oceanic warming, and how these changes have affected livelihoods in communities local to the Uummannaq region of West Greenland. The results will improve institutional knowledge of environmental change in the Arctic and prediction of its associated impacts, as well as strengthen US relations in an area of, potentially global, strategic and economic importance.The project will co-produce shorefast ice knowledge by leveraging large satellite remote sensing datasets, community-based monitoring and local and Indigenous knowledge. First, observations from high-resolution optical satellite sensors will be supplemented with knowledge gathered from local residents. A community-based monitoring program will then be initiated using small multi-rotor UAVs to document key shorefast ice processes (e.g. formation and break-up) as they happen. The quantitative and qualitative shorefast ice knowledge generated by these two activities will be used to understand not only how the shorefast ice has changed but how these changes matter to individuals and communities in the Uummannaq region. The involvement of residents and institutions in Uummannaq at all stages of the project, in combination with ongoing observations, will lay the foundations for ongoing community support and enable new insights into the complex social, cultural and economic changes caused by rapid environmental change. The findings will also enhance the ability of local residents and institutions to make informed and embedded choices concerning natural resource governance and management, as well as choices about individual and collective trajectories towards a desirable and sustainable future.This award is cofunded by the Office of International Science & Engineering.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.
