Underwater acoustics is the study of the propagation of sound in water and the interaction of the acoustic waves with the water, its contents and its boundaries[1]. Due to the heavy signal loss and fading undergone by EM waves underwater, acoustic waves are the main medium of propagation of signals under the water. This makes it immensely important to understand the propagation characteristics and model them for various applications, including but not limited to ocean mapping, military and sonar applications, etc, more so in the IOR due to its strategic location wrt military and trade aspects.
