Water quality (DP1.20288.001)

The water quality sondes are deployed at stream sensor sets and lake and river buoys. At stream sites, the sondes are affixed to a post at a static depth relative to the stream bottom. The upstream sensor set #1 (S1) collects specific conductance, dissolved oxygen, pH, chlorophyll, and turbidity, but no fDOM. The downstream sensor set #2 (S2) collects specific conductance, dissolved oxygen, pH, chlorophyll, turbidity and fDOM. The buoy-deployed multisondes collect specific conductance, dissolved oxygen, pH, chlorophyll, turbidity, fDOM, and depth. At all but the Flint River, GA (FLNT) buoys, the water quality multisonde is fixed to a profiling winch to collect data from multiple depths every 4 hours and from 0.5 m parked depth when not profiling. Due to the high velocity of the Flint River (FLNT), one multisonde is deployed at a fixed depth of 0.5 m below the water surface.
