Rivers play a central role in society and there is great interest in monitoring and understanding river health. But these systems are also dynamic in space and time, making it difficult to detect important events that disproportionately influence their form and function. To better understand times (‘hot moments’) and places (‘hot spots’) of high biogeochemical activity in a large, agriculture-dominated river basin, we will combine the technological prowess of high frequency sensors with the power of an engaged downstream community. First, we will use an automated platform with real-time capabilities, deployed in the Saskatchewan River Delta, to understand how ecosystem metabolism and nutrient and sediment flux varies during snowmelt, baseflow and during dam releases. Next we will mount GPS-enabled sondes on canoes for annual trips carried out by a high school in the delta community that travels the length of the river. On these trips, the sondes will collect spatially-explicit water quality data to identify important places for nutrient inputs and transformations. Finally, we will collaborate with the Great Rivers Ecological Observation Network (GREON

河流在社会中发挥着核心作用，人们对监测和了解河流健康有着极大的兴趣。但这些系统在空间和时间上也是动态的，因此很难发现对其形式和功能产生不成比例影响的重要事件。为了更好地了解以农业为主的大型流域中高地球化学活动的时间（“热点”）和地点（“热点”），我们将联合收割机的技术实力与下游社区的力量相结合。 首先，我们将使用具有实时功能的自动化平台，部署在萨斯喀彻温河三角洲，以了解生态系统的新陈代谢和营养物质和沉积物通量如何在融雪，基流和大坝释放期间变化。 接下来，我们将在独木舟上安装GPS探测器，由三角洲社区的一所高中进行年度旅行，旅行的长度。 在这些行程中，探测器将收集空间上明确的水质数据，以确定营养物质输入和转化的重要地点。 最后，我们将与大河生态观测网络（GREON）合作
