What Is Marine Bioacoustics?
Simply stated, marine bioacoustics can be defined as the use of acoustics to study any facets of marine animals such as auditory capabilities, sound production, communications, foraging behavior, in short, anything having to do with their natural history. Acoustic energy propagates in water more efficiently than almost any form of energy and can be utilized by animals for a variety of purposes and also by scientists interested in studying animal life in the ocean. Electromagnetic, thermal, light and other forms of energy are severely attenuated in water. Therefore, the most effective method for an animal to perform various functions associated with its life cycle such as communications, navigation, obstacle avoidance, prey avoidance and detection is by the use of acoustics in either an active echolocation or passive (listening) manner. Similarly, the location, movement, social interaction, density and other facets of animal life in the sea can be studied by...
