1. The technique of remote sensing in which an instrument sends acoustic waves vertically and receives reflections from atmospheric features such as inversions or turbulent layers. 2. A representation of the vertical profile of one or more of the state variables of a fluid body (typically the ocean or atmosphere) deduced from variations in reflected acoustic energy. 3. A particular measurement of depth of water below an instrument (either at the surface or at some moored depth) computed from the travel time of an acoustic pulse emitted by the acoustic sounder.
Industry:Weather
An imaging technique in which information is collected from beams of acoustic radiations that have passed through an object, generally in the form representing a two-dimensional slice through the object. In oceanography, acoustic tomography consists of an inverse technique that uses acoustic signals to sample the interior of the ocean. In this way, the temperature structure of the interior ocean can be reconstructed from acoustic signals in multiple vertical planes.
Industry:Weather
A device, such as an underwater hydrophone, that converts acoustic energy into electromagnetic energy; or a device, such as an acoustic source, that converts electromagnetic energy into acoustic energy.
Industry:Weather
A device used in underwater navigation that responds with an acoustic code when interrogated by an acoustic signal from a ship.
Industry:Weather
An instrument for making direct measurements of the speed of sound in oceans and lakes.

From its Greek origin, akoustikus, meaning related to hearing, acoustic ought to be restricted to sound audible to humans (or animals). Although this is often the sense in which it used, the term is also used to embrace sound of all frequencies.

Industry:Weather
A wave disturbance with restoring forces that include buoyancy and the elastic compressibility of the fluid medium.
Industry:Weather
