The Geotechnical Laboratory has an Aquadrop Profiler manufactured by Nortek. The Aquadopp® Profiler measures water column current profiles using acoustic Doppler technology. Designed for a wide range of applications from coasts to rivers, the Aqudopp® Profiler is a small, lightweight, and cost-effective solution for shallow water (<300 ft) deployments. It can be deployed on the bottom, on a buoy, or on a mooring line. The profiler is a complete system and includes all parts required for a self-contained deployment with internal batteries and a data logger.
The Aquadopp® Profiler measures high-quality, accurate, and unbiased three-component (East, North, Up) current profile data using acoustic Doppler technology. It can measure speed and direction in up to 128 different layers of the water column.
System electronics integrate Doppler velocity with temperature, pressure, tilt, and compass information – all standard with each instrument.
The Aquadopp® Profiler has a built-in solid state data recorder and batteries. State-of-the-art power management and miniaturized electronics combined in a compact single-canister design that is suitable for real-time operation or self-contained deployments.
