    en.wikipedia.org/wiki/List_of_unexplained_sounds

    Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.

  3. Refraction (sound) - Wikipedia

    en.wikipedia.org/wiki/Refraction_(sound)

    This effect is responsible for guided propagation of sound waves over long distances in the ocean and in the atmosphere. In the atmosphere, vertical gradients of wind speed and temperature lead to refraction. [1] The wind speed is usually increasing with height, which leads to a downward bending of the sound rays towards the ground.

  4. Underwater acoustics - Wikipedia

    en.wikipedia.org/wiki/Underwater_acoustics

    Output of a computer model of underwater acoustic propagation in a simplified ocean environment. A seafloor map produced by multibeam sonar. Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries.

  5. SOFAR channel - Wikipedia

    en.wikipedia.org/wiki/SOFAR_channel

    The SOFAR channel (short for sound fixing and ranging channel), or deep sound channel (DSC), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.

  6. Geometrical acoustics - Wikipedia

    en.wikipedia.org/wiki/Geometrical_acoustics

    The ray concept is used in designing sound focusing systems. Also, the approximate theory of sound propagation in inhomogeneous media (such as the ocean and the atmosphere) has been developed largely on the basis of the laws of geometrical acoustics. [3] [4]

  7. Sound speed gradient - Wikipedia

    en.wikipedia.org/wiki/Sound_speed_gradient

    In acoustics, the sound speed gradient is the rate of change of the speed of sound with distance, for example with depth in the ocean, [1] or height in the Earth's atmosphere. A sound speed gradient leads to refraction of sound wavefronts in the direction of lower sound speed, causing the sound rays to follow a curved path.

  8. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.

  9. Microbarom - Wikipedia

    en.wikipedia.org/wiki/Microbarom

    The ocean motion generated by this "equivalent pressure" is then transmitted to the atmosphere. If the wave groups travel faster than the sound speed, microbaroms are generated, with propagation directions closer to the vertical for the faster wave groups. Pressure field in the ocean and atmosphere associated to groups made by opposing wave trains.
