A methodology is developed to measure ultrasonic velocity of submerged aquatic vegetation tissue, in particular, macroalgae, in a nondestructive and efficient manner. An entire thallus is submerged in artificial seawater-filled tank through which many ultrasonic pulse-echo measurements are recorded while thallus parts are randomly displaced. Average sound speed of tissue is estimated from normal fit to extracted travel times given measured total volume fraction of tissue and travel time in water alone. For species the resulting values for sound speed 1573.4  4.8 m s−1 and adiabatic compressibility 3.134 10−10  1.34 10−11 Pa−1 at 18 C agree with more laborious and destructive methods.
