Using Sound to Visualize Currents
Ocean Networks Canada
Published: 3 February 2012
ADCPs from Nortek and RDI use sound beams to measure 3D ocean currents by analyzing Doppler shifts from particles in the water. Installed across Ocean Networks Canada's sites, these sensors aid in studying deep-sea currents, marine life, and ecosystem changes.
