Book excerpt: As part of a program of in situ acoustical measurements in ocean sediments, an experimental investigation was started in order to examine the feasibility of measuring shear wave speed, shear wave attenuation, and bulk density by using instruments similar to the compressional wave profilometer developed previously. Measurements were made of the shear wave speed and attenuation in high porosity koalinite clay as the clay consolidated over a period of time. Experimential and theoretical investigation of the measurement of bulk density by acoustical means indicates that the radiation impedance of a driven piezoelectric ceramic transducer can be determined by measuring the electrical input to the transducer. Preliminary measurements of these parameters are reported. As an adjunct to the other measurements, physical properties of the sediments used in the laboratory measurements were determined and are reported.
