Research on the origin of seismic noise [1] indicates that the low frequency part of the spectrum (below 1 Hz) is principally due to natural causes, chiefly ocean waves.In particular the globally observed peak between 0.1 and 0.3 Hz is clearly associated with the interaction of water waves of nearly equal frequencies but probating in opposing directions.
The sound is consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor. [3] The sound's source was roughly triangulated to a remote point in the south Pacific Ocean west of the southern tip of South America, and the sound was detected several times by the Equatorial Pacific Ocean autonomous ...

In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface.
The sound's source was roughly triangulated to , a remote point in the South Pacific Ocean west of the southern tip of South AmericaThe sound was detected by the Equatorial Pacific Ocean autonomous hydrophone array, [1] a system of hydrophones primarily used to monitor undersea seismicity, ice noise, and marine mammal population and migration.
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.
In geography, a sound is a smaller body of water usually connected to a sea or an ocean. A sound may be an inlet that is deeper than a bight and wider than a fjord ; or a narrow sea channel or an ocean channel between two land masses, such as a strait ; or also a lagoon between a barrier island and the mainland.

In February 2000, the British oceanographic research vessel RRS Discovery, operating in the Atlantic Ocean over the Rockall Trough west of Scotland, encountered the largest waves ever recorded by scientific instruments in the open ocean, with a significant wave height of 29.1 metres (95 ft) and individual waves up to 18.5 metres (61 ft).
