The Same Reflective Characteristics for Different Effective Geoacoustic Parameters in Different Models

Acoustical properties of the sea bottom can be described with a geoacoustic (GA) model comprising several layers characterized by the values of GA parameters, such as sound speed, density, sound absorption, and thickness. As the parameter values are difficult to measure directly, they are often estimated using inversion methods. Although GA inversion is the most economical method to infer the seab...
