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，并且对监测和了解河流健康有很大的兴趣。但是这些系统在时空上也是动态的，因此很难检测到不成比例地影响其形式和功能的重要事件。为了更好地了解，在以农业为主导的大型河流中，高生物地球化学活动的时代（“热点”）和位置（“热点”），我们将将高频传感器的技术实力与一个参与的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，该平台部署在萨斯喀彻温省河三角洲，以了解如何在融雪，基础流量和大坝释放期间在融雪，基础流量期间的生态系统代谢以及营养和沉积物变化。接下来，我们将在独木舟上安装支持GPS的SONDES，每年由三角洲社区的一所高中旅行，该旅行沿着河流的长度进行。在这些旅行中，SONDES将收集空间说明的水质数据，以确定营养输入和转化的重要位置。最后，我们将与Great Rivers生态观察网络（Greon）合作
