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.Northern communities in Alaska and Canada rely upon productive fisheries. For many of these communities, rivers are used to access fishing and hunting grounds and to transport supplies during ice-free seasons and over river-ice in winter. As the Arctic and its rivers continue to warm, the ultimate impacts on people, their fisheries and winter travel corridors are highly uncertain. Improved understanding of the ongoing and possible future changes requires close partnership among Native groups and researchers from diverse scientific disciplines. This project is a collaboration among the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado Boulder (CU), the U.S. Geological Survey (USGS), the Yukon River Inter-Tribal Watershed Council (YRITWC), the National Center for Atmospheric Research (NCAR), the Institute for Tribal Environmental Professionals (ITEP) at North Arizona University (NAU), and two major Canadian universities. The YRITWC is a non-profit organization of 74 First Nations and Tribes that conducts monitoring of the Yukon River Watershed. Three Indigenous interns are working with YRITWC and USGS researchers and staff to enhance the community-based and federal river monitoring networks with automated water quality sensors. The new data are being used by researchers to monitor river conditions and change and to improve computer simulations of rivers, ice, and fish. Outreach to Indigenous K-12 students in the communities where monitoring is being conducted will include traveling lectures and an ask-scientists website. A Native Advisory Council will be formed in Year 1 to provide input into research directions and refinements and to ensure the production of useable outcomes. Importantly, the Council will guide the agenda of a two-day Arctic Rivers Summit in project Year 3 and the selection of 42 Indigenous community members to receive a scholarship to attend the Summit. The Summit will bring together Tribal and First Nation resource managers, Arctic and Boreal community members, and academic, federal, state, and provincial researchers to unify the state of knowledge on Arctic Rivers as a community of observers, investigators, knowledge holders, and stewards. Results from the Summit will include a white paper co-authored by all attendees. Researchers from NCAR and CU are conducting computer simulations of weather, streamflow, river ice, and water temperature for historical and potential future climate conditions over Alaska and western Canada. The data are being used by USGS and CU scientists to assess potential risks to Arctic river fish species. The project results will be communicated through co-produced scenarios jointly developed by all investigators and community members and designed to make future scenarios of Arctic change and potential societal impacts tangible and relatable to a broad audience. Thus, the project is assessing how socially important fish habitat and river-ice transport corridors of Arctic rivers may be impacted by climate-driven environmental changes.Changes in temperature, precipitation, snowmelt and streamflow timing, ice-cover, permafrost, hydrologic connectivity, river geochemistry, and groundwater are poorly characterized in northern regions, and the integrated effects on rivers and fish are critically unresolved. This project is advancing collective understanding of terrestrial hydrologic change and the potential impacts on rivers, fish, and communities in the Arctic. The project facilitates knowledge co-production through Indigenous community-based monitoring of rivers, Native engagement and oversight, ethnographic methods, and advances in climate, hydrologic, and river-ice, and fish bioenergetic models. Indigenous Knowledge (IK) and Western Science (WS) will be used to co-develop scenarios of past and plausible future conditions. An Arctic Rivers Summit co-developed by Tribal Environmental experts, YRITWC, USGS, and a Native Advisory Council identifying IK and WS baseline conditions of rivers and fish. This includes continuous water quality measurements of major rivers to observe hydrologic conditions and guide model development. The Regional Arctic System Model and the Community Terrestrial Systems Model are coupled to simulate river ice and water temperature with a chain of process-based models. Historical reanalysis, verified against baseline conditions, and future climate scenarios are simulated, and a fish bioenergetics model is being used to assess vulnerabilities of co-identified river-run Arctic fish species. Rich scenarios with IK of past events, changes, community challenges and adaptation successes will provide unique context to best communicate future model projections and impacts on the social, built and natural Arctic environment. Combining IK, climate and hydrologic modeling techniques with parallel advances in river ice, stream temperature, and fish models, the project collectively identifies convergent opportunities to monitor, map, model, assess, and communicate climate sensitivities of Arctic and boreal hydrology, rivers, and fish with respect to Indigenous culture, livelihood, transportation, and subsistence.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.

新北极航行（NNA）是NSF的十大创意之一。NNA项目解决快速变化的北极地区的趋同科学挑战。北极研究需要为国家、更大地区和地球仪的经济、安全和复原力提供信息。NNA授权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。这个奖项实现了这一目标的一部分。阿拉斯加和加拿大的北方社区依赖于多产的渔业。对其中许多社区来说，河流被用来进入渔场和狩猎场，并在无冰季节和冬季在河冰上运输物资。随着北极及其河流持续变暖，对人类、渔业和冬季旅行走廊的最终影响非常不确定。要更好地了解正在发生的和未来可能发生的变化，就需要土著群体和来自不同科学学科的研究人员之间建立密切的伙伴关系。该项目是科罗拉多博尔德大学北极和高山研究所、美国地质调查局、育空地区河部落间流域理事会、国家大气研究中心、北亚利桑那大学部落环境专业人员研究所和加拿大两所主要大学之间的合作项目。YRITWC是一个由74个原住民和部落组成的非营利组织，对育空地区河流域进行监测。三名土著实习生正在与YRITWC和美国地质勘探局的研究人员和工作人员合作，利用自动水质传感器加强以社区为基础的和联邦河流监测网络。研究人员正在使用这些新数据来监测河流状况和变化，并改进河流，冰和鱼类的计算机模拟。在进行监测的社区，对土著K-12学生的外联活动将包括巡回讲座和一个询问科学家网站。土著咨询理事会将在第一年成立，为研究方向和改进提供投入，并确保产生有用的成果。重要的是，理事会将指导项目第三年为期两天的北极河流首脑会议的议程，并挑选42名土著社区成员获得奖学金参加首脑会议。峰会将汇集部落和第一民族资源管理人员，北极和北方社区成员，以及学术，联邦，州和省的研究人员，统一北极河流的知识状态，作为观察员，调查员，知识持有者和管理员的社区。峰会的成果将包括一份由所有与会者共同撰写的白色文件。来自NCAR和CU的研究人员正在对阿拉斯加和加拿大西部的历史和潜在未来气候条件进行天气，流量，河冰和水温的计算机模拟。美国地质勘探局和CU的科学家正在使用这些数据来评估北极河流鱼类的潜在风险。项目结果将通过所有调查人员和社区成员共同开发的共同制作的情景进行交流，旨在使北极变化和潜在社会影响的未来情景切实可见并与广大受众相关。因此，该项目正在评估具有社会重要性的鱼类栖息地和北极河流的河冰运输走廊如何受到气候驱动的环境变化的影响，北方地区的温度、降水、融雪和径流时间、冰盖、永久冻土、水文连通性、河流地球化学和地下水的变化特征很差，对河流和鱼类的综合影响尚未得到严重解决。该项目正在推进对北极陆地水文变化及其对河流、鱼类和社区的潜在影响的集体理解。该项目通过以土著社区为基础的河流监测、土著参与和监督、人种学方法以及气候、水文、河冰和鱼类生物能量模型的进步，促进知识的共同生产。土著知识（IK）和西方科学（WS）将被用来共同开发过去和未来可能出现的情况。北极河流峰会由部落环境专家、YRITWC、USGS和土著咨询理事会共同开发，确定河流和鱼类的IK和WS基线条件。这包括对主要河流进行连续的水质测量，以观察水文条件并指导模型开发。区域北极系统模型和社区陆地系统模型耦合起来，用一系列基于过程的模型模拟河冰和水温。历史再分析，验证对基线条件，未来的气候情景进行了模拟，鱼类生物能量学模型正在被用来评估共同确定的河流运行的北极鱼类物种的脆弱性。过去的事件，变化，社区挑战和适应成功的丰富情景将提供独特的背景，以最好地传达未来模型预测和对社会，建筑和自然北极环境的影响。该项目将IK、气候和水文建模技术与河冰、溪流温度和鱼类模型的并行进展相结合，共同确定了集中的机会，以监测、绘制、建模、评估和交流北极和北方水文、河流和鱼类的气候敏感性。土著文化、生计、交通、该奖项反映了NSF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。
