LADCP

A lowered Acoustic Doppler Current Profiler (ADCP) is an acoustic flow measurement system used for vertical profiling of ocean currents. It utilizes the Doppler effect of sound waves to measure current speed and direction at various depths within the water column. Typically mounted on a hydrographic observation frame, the instrument is lowered vertically to the target depth and continuously records data during the ascent. Its key advantage is providing a complete flow profile from the surface to deep waters, aiding the analysis of ocean current structures, internal waves, tides, and mid-depth water dynamics. This system is often operated alongside other hydrographic and chemical sensors for comprehensive multi-parameter observations. It is widely applied in physical oceanography research, energy development assessments, and marine environmental monitoring, serving as a crucial tool for understanding water body dynamics.
