Our approach is inherently multi-disciplinary, blending the key disciplines of geology/geophysics (G&G) and acoustics, linked by the field of geoacoustics. For many years, the underwater acoustics community has probed sediment geoacoustics through inverse modeling of acoustic measurements (e.g., propagation, reverberation) or via empirical relations (e.g., Hamilton, 1980) or physics-based model...

Although the emphasis in underwater acoustics for the last few decades has been in low-frequency acoustics, motivated by long range detection of submarines, there has been a continuing use of high-frequency acoustics in traditional specialized applications such as bottom mapping, mine hunting, torpedo homing and under ice navigation. The attractive characteristics of high-frequency sonar, high ...

Currently, UWASN (Underwater Acoustic Sensor Network) has been researched as a branch of sensor networks. UWASNs use a transmission media different from terrestrial wireless sensor networks. That is, the former uses acoustic waves and the latter uses radio waves for communication. G/W (Gateway)s in UWASNs are nodes for relaying data transmission between a UWASN and a terrestrial wireless sensor...

A very short introduction of the principles of light diffraction by ultrasonic waves is followed by a discussion of acousto-optic imaging (schlieren) techniques. This method is often useful to obtain qualitative results of various acoustic phenomena in ultrasonics, underwater sound, material characterization, transducer performance and other areas of acoustics. Examples from different fields of...

Submarine confinement is a key element in most underwater communication application. Acoustic communication of movable submarine networks face with many unmatched inquisitive like long arch, high communication power consumption and convergence mobility. Unrushed signal enlargement allows multiple packets to coordinate travel through the submarine channel, which is harsh to improve the overall t...
