The experimental results of measurement of the scalar and vector characteristics of an acoustic field in shallow water with a carbon bottom are analyzed. Simultaneous recording of the sound pressure and three orthogonal components of particle velocity was carried out using a sound pressure receiver and a vector receiver. A towed transducer was the source of the tone signal; the noise signal from a passing ship was a source located near the water—air boundary. In the spatial decay of the sound field components, significant variations in the levels of sound pressure and particle velocity components were observed, regardless of the depth of the sound source. When the sound source was located in the depth of the water layer, the dependence of the spatial decrease in the acoustic field components is diverse, while when the noise signal source was located below the water—air interface, the decay character of the sound pressure amplitudes and of the vertical component of the particle velocity were the same throughout the measurement path.
