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.

岸冰（也被称为陆地冰）是附着在海岸线上的海冰。由于滨冰不随风和洋流漂移，因此在北极形成了野生动物的重要栖息地和人类自给食品生产和运输的平台。随着气候变暖，北极地区的居民报告说，北极冰层在今年早些时候就开始破裂，而且比几十年前更薄。这些环境变化威胁到依赖滨冰的野生动物和传统人类活动的可持续性。尽管具有重要意义，但尚未对格陵兰岛的滨冰进行全面的多学科评估。因此，该项目旨在了解滨冰如何对大气和海洋变暖做出反应，以及这些变化如何影响西格陵兰Uummannaq地区当地社区的生计。研究结果将提高对北极环境变化的制度性认识，并预测其相关影响，同时加强美国在这个具有潜在全球、战略和经济重要性的领域的关系。该项目将利用大型卫星遥感数据集、以社区为基础的监测以及当地和土著知识，共同生产速冻知识。首先，高分辨率光学卫星传感器的观测结果将与当地居民收集的知识相辅相成。然后将启动一个基于社区的监测计划，使用小型多旋翼无人机记录关键的滨速冰过程（例如形成和破裂）。这两项活动产生的定量和定性滨冰知识不仅将用于了解滨冰如何变化，而且将用于了解这些变化对乌曼纳克地区个人和社区的影响。Uummannaq的居民和机构参与项目的所有阶段，结合正在进行的观察，将为持续的社区支持奠定基础，并使人们能够对迅速的环境变化引起的复杂的社会、文化和经济变化有新的认识。调查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深入选择的能力，以及对个人和集体走向理想和可持续未来的轨迹做出选择的能力。该奖项由国际科学与工程办公室共同资助。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
