Choptank River Vertical Profiler
The vertical profiling system consists of a controller, winch, and data logging and telemetry system mounted on a floating platform. The winch is used to lower the datasonde down into the water column. The Choptank River vertical profiler is currently setup to sample at 0.5, 1, 2, 3, 4 and 5 meters every hour. Data from the individual profiles are interpolated to generate a graphic which depicts water quality conditions over time.
