Water-quality sonde to be deployed from May through October in Grand Rapids, Michigan, to collect 15-minute measurements of dissolved oxygen, conductance, water temperature, turbidity, fluorescent dissolved organic matter (fDOM), and tryptophan-like fluorescence. This end-on view of the water-quality sonde shows each of the individual sensors.
