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.Hundreds of glaciers around the Arctic flow into ocean fjords that are several miles wide, tens of miles long, and thousands of feet deep. Glacial meltwater and sediments released into the fjords make their waters nutrient-rich to the extent that glacial fjords, all over the Arctic region, are characterized by prosperous marine ecosystems, featuring a high density of seabirds, marine mammals, and fishes. As a result, many Arctic settlements are located near glacial fjords that, through their ecosystems, support hunting and fishing and contribute to the regional economy. As the Arctic warms, however, glaciers are melting and retreating, and ocean waters are expected to warm, thus affecting these glacial fjord ecosystems and the human communities they support. Within this project, researchers will take advantage of new projections of how the glaciers and the ocean will change, combined with improved understanding of glacial fjords and their ecosystems, to investigate change at two distinct glacial fjords in Greenland. The long-term goal of this project is to provide relevant planning information to the two communities in Greenland and develop a method that can be applied to other communities around the Arctic.The international research team, composed of glaciologists, oceanographers, marine ecosystem scientists, and social scientists, will use available data and hold discussions with community members to identify the relevant socioecological system components and linkages for two glacial fjord systems, one in Northwest Greenland and one in Southeast Greenland. This systems understanding will be combined with glacier and local climate (ocean and atmosphere) projections to determine how climate projections can be optimally utilized for sustainable planning and adaptation. This research will involve synthesis of existing information and co-production of knowledge with the two communities. A final workshop involving Greenland Government officials and other Arctic organizations will be used to develop a framework that can be applied throughout the Arctic.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.

导航新北极（NNA）是美国国家科学基金会的十大构想之一。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、安全和复原力提供信息。NNA支持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。这个奖项部分实现了这一目标。北极周围成百上千的冰川流入几英里宽、几十英里长、数千英尺深的海洋峡湾。冰川融水和沉积物释放到峡湾，使其水域营养丰富，以至于整个北极地区的冰川峡湾都以海洋生态系统繁荣为特征，海鸟、海洋哺乳动物和鱼类密度高。因此，许多北极定居点位于冰川峡湾附近，这些峡湾通过其生态系统支持狩猎和捕鱼，并为区域经济做出贡献。然而，随着北极变暖，冰川正在融化和退缩，海水预计会变暖，从而影响这些冰川峡湾生态系统及其所支持的人类社区。在这个项目中，研究人员将利用冰川和海洋将如何变化的新预测，结合对冰川峡湾及其生态系统的进一步了解，调查格陵兰岛两个不同的冰川峡湾的变化。该项目的长期目标是为格陵兰岛的两个社区提供相关的规划信息，并开发一种可应用于北极周围其他社区的方法。由冰川学家、海洋学家、海洋生态系统科学家和社会科学家组成的国际研究小组将利用现有数据并与社区成员进行讨论，以确定两个冰川峡湾系统的相关社会生态系统组成部分和联系，一个在格陵兰岛西北部，一个在格陵兰岛东南部。这种对系统的理解将与冰川和当地气候（海洋和大气）预测相结合，以确定如何将气候预测最佳地用于可持续规划和适应。这项研究将涉及现有信息的综合和与两个社区共同生产知识。将利用格陵兰政府官员和其他北极组织参加的最后一次讲习班制定一个可在整个北极地区适用的框架。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。
