Description

[Chapter Abstract] Acoustic methods are widely used for the production of physical, environmental and biological data required for the responsible management of marine resources, such as coral reefs. Here, we review the basic physical properties of sound in water that can be harnessed for active or passive acoustic remote sensing systems. Sound, by assessing the return characteristics of emitted sound waves, can be used to derive information on seafloor topography via depth (obtained by measuring travel time), on seafloor makeup (obtained by measuring backscatter intensity), or on water column characteristics (obtained by measuring Doppler shifts). Sound is also used to track organisms such as fish or even to create images by harnessing natural sound sources to “illuminate” objects like fish. Acoustic methods have a place in the toolbox of every coral reef manager.
