Lishui represents the deep sea under which the ocean surges and waves; [1] [4] it is therefore typically topped with "still water" (woshui (Chinese: 卧水; pinyin: wòshuǐ), also called pingshui (Chinese: 平水; pinyin: píngshuǐ)), which is represented by concentric semicircle patterns which runs horizontally.
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.
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 boarded windows block the view of the ocean, but he can still hear the rumbling, followed by a few seconds of respite before another wave slams against the wall. ... Nor'easter sends enormous ...
Today's top weather news for Wednesday, Dec. 11, 2024: Millions of people along the East Coast are bracing for severe weather, strong winds and heavy rain that will slow travel along the I-95 ...
A Royal Caribbean cruise ship ran into high winds and rough seas in the Atlantic Ocean, forcing the Florida-bound vessel to retreat back to its home port in Cape Liberty, New Jersey.
Aside from sound produced by the acoustic source, the hydrophones record background noise caused by natural processes such as breaking of wind waves at the ocean surface. These other, unwanted sounds are often much louder than sound reflected from thermohaline boundaries. Use of signal-processing filters quietens unwanted sounds and increases ...

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.
