ULTRASONIC VELOCITY AND ABSORPTION MEASUREMENTS
Abstract
Sound velocity measurements were made of water, chemical solutions, and particulate suspensions. Velocity and absorption measurements of suspensions of biological material up to 0.25 gram/ liter were attempted but no differences could be observed compared to water alone. Some estimates were made of the effects which plankton might have on the propagation of underwater sound from the data of earlier investigators working with other biological material. It appears from this very limited experimental evidence that plankton in the ocean have an insignificant effect on the absorption and velocity of sound, as compared to the physical properties of the water itself.
