Experimental investigations of acoustic field in sea shelf zone

Developed experimental facility allows one to generate acoustic pressure within the intervals from 105 to 106 Pa with an affective system of matching layers of bottom, water and ice. Theoretical and experimental investigations showed the possibility of information transfer in a shallow sea under an ice layer. Experimental acoustic system allows one to make measurements in a wide frequency range from 40 to 1100 Hz. The conducted investigation can be used to develop effective remote communication and to model earthquake acoustic precursor measurements.
