Part 1: This continuation of the Indigenous Observing Network (ION) project (now ION 2.0) will be led by the Yukon River Intertribal Watershed Council (YRITWC) in partnership with the University of Alaska-Fairbanks. ION 2.0 will continue measurement of water quality constituents and expand the observation and monitoring program to include measurements of changes in permafrost depth due to thawing of the active layer at numerous of the long-term water quality monitoring sites. The ION project has documented the long-term changes in major ion chemistry that have occurred over three decades throughout the Yukon River Watershed. The investigators have interpreted these changes as being driven by thawing of discontinuous permafrost throughout this large Arctic watershed and complementary measurements of the active layer will support further interpretation and modelling. This project involves significant co-production of knowledge with members of Indigenous communities and capacity building through training in sampling methods, and sample and data analysis. Part 2: This project will continue the long-term water quality monitoring at many sites in the Yukon River Watershed that have been conducted by the Indigenous Observing Network (ION) project. The ION 2.0 project will be led by the Yukon River Intertribal Watershed Council (YRITWC) in partnership with the University of Alaska-Fairbanks. ION 2.0 will expand the observation and monitoring program to include measurements of changes in permafrost depth at numerous of the long-term water quality monitoring sites. These changes occur due to thawing of the active layer driven by the changing Arctic climate. The ION project has shown that changes in major ion chemistry have occurred over three decades throughout the Yukon River Watershed due to the thawing of discontinuous permafrost. The investigators have interpreted the complementary measurements of the active layer will support further interpretation and modelling. This project involves significant co-production of knowledge with members of Indigenous communities and capacity building through training in sampling methods, and sample and data analysis.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.

第一部分：土著观测网络（ION）项目（现为ION 2.0）的延续将由育空河部落间流域委员会（YRITWC）与阿拉斯加-费尔班克斯大学合作领导。ion2.0将继续测量水质成分，并扩大观察和监测计划，包括在许多长期水质监测点测量由于活动层融化而导致的永久冻土深度变化。离子项目记录了育空河流域30多年来主要离子化学的长期变化。研究人员解释说，这些变化是由整个北极大流域不连续的永久冻土融化造成的，对活动层的补充测量将支持进一步的解释和建模。该项目涉及与土著社区成员共同生产大量知识，并通过抽样方法、抽样和数据分析方面的培训进行能力建设。第二部分：该项目将继续在育空河流域的许多地点进行长期的水质监测，这些监测是由土著观测网络（ION）项目进行的。ION 2.0项目将由育空河部落间流域委员会（YRITWC）与阿拉斯加-费尔班克斯大学合作领导。ion2.0将扩展观测和监测计划，包括在许多长期水质监测点测量永久冻土深度的变化。这些变化是由于北极气候变化导致活动层融化造成的。离子项目表明，由于不连续的永久冻土融化，育空河流域的主要离子化学成分在过去30年里发生了变化。研究人员解释说，对活动层的补充测量将支持进一步的解释和建模。该项目涉及与土著社区成员共同生产大量知识，并通过抽样方法、抽样和数据分析方面的培训进行能力建设。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。
