This is the common definition for Acoustic-Doppler Current Profilers, but other definitions maybe discussed within the wiki.
Sonar echo returns are time-gated to produce a profile of currents over some depth range extending away from the instrument. The range and resolution of ADCP data are constrained by the instrument sonar frequency and the set-up configuration. These can be mounted on seabed landers, tethered to moorings, added to CTD rosettes and or installed within ship hulls.
