Fishing Bay 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 Tred Avon vertical profiler is currently setup to sample at 0.5, 1, 2, 3, and 4 meters every hour. Data from the individual profiles are interpolated to generate a graphic which depicts water quality conditions over time.
