Lamb waves propagate in solid plates or spheres. [1] They are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the direction perpendicular to the plate. In 1917, the English mathematician Horace Lamb published his classic analysis and description of acoustic waves of this type. Their ...
Incoming wave (red) reflected at the wall produces the outgoing wave (blue), both being overlaid resulting in the clapotis (black). In hydrodynamics, a clapotis (from French for "lapping of water") is a non-breaking standing wave pattern, caused for example, by the reflection of a traveling surface wave train from a near vertical shoreline like a breakwater, seawall or steep cliff.
A deep blue colored wave viewed from the water surface near Encinitas, California, United States. The Pacific Ocean contains some of the most deep blue colored waters in the world. The reason that open-ocean waters appear blue is that they are very clear, somewhat similar to pure water, and have few materials present or very tiny particles only.
Coral reefs, the so-called "rainforests of the sea", occupy less than 0.1 percent of the world's ocean surface, yet their ecosystems include 25 percent of all marine species. [85] The best-known are tropical coral reefs such as Australia's Great Barrier Reef , but cold water reefs harbour a wide array of species including corals (only six of ...
Most of the ocean is blue in color, but in some places the ocean is blue-green, green, or even yellow to brown. [64] Blue ocean color is a result of several factors. First, water preferentially absorbs red light, which means that blue light remains and is reflected back out of the water.
The University of Oslo has conducted research into crossing sea state and rogue wave probability during the Prestige accident; nonlinear wind-waves, their modification by tidal currents, and application to Norwegian coastal waters; general analysis of realistic ocean waves; modelling of currents and waves for sea structures and extreme wave ...

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.
