Supplemental figures for "Impacts of Aquatic Vegetation Dynamics on Nitrate Removal in Karst Agricultural Streams: Insights From Unmanned Aircraft Systems and In Situ Sensing"

<p>In this manuscript, we highlight the following:</p> <ol><li>Coupling automated segmentation and classification procedures to visible spectrum imagery from UAS captured spatial and temporal distribution of floating aquatic macrophytes in a karst agricultural stream.</li><li>High-frequency in situ sensors were utilized to quantify stream metabolism for the karst agroecosystem, and findings contrasted similar systems, reflecting the regulation of the low-flow regime facilitating duckweed proliferation.</li><li>Diurnal nitrate variability shifted due to changes in aquatic vegetation, illustrating contrasting processes governing nitrate removal in the channel throughout the growing season.</li><li>Comparing results of nitrate monitoring with an extreme learning machine model illustrated the utility of coupling the in situ and aerial imagery for identifying limitations of model performance.</li></ol> <p><br></p>
