Vertical profiles of water motion and turbulence were obtained using a coherent Doppler sonar installed in a tidal inlet between Biscayne Bay, Florida and Atlantic Ocean. Several estimates of mean Doppler velocity, Doppler spectrum variance, and mean backscattering signal intensity were calculated. The vertical profiles showed a consistent decrease of mean velocity moving down from the water surface. Backscattering signal intensity showed a strong correlation between sonic turbidity and the tide stage. The measured Reynolds stress was larger than the stress derived from the mean velocity profile during accelerating flow and smaller during decelerating flow.
