Their names are given by the color of the water. Sometimes a system of color symbolism was used as the following method green or light blue for east, black or dark for north, white for west, and red for south. This method is called cardinal directions. [1] There are other theories but these two methods of colors are also used.
Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [1]

A dark sky place is exactly what it sounds like. Modern lighting in cities and towns contributes to light pollution, which obscures many stars from sight for those who live in urban environments.
Green flashes may be observed from any altitude (even from an aircraft). They are usually seen above an unobstructed horizon, such as over the ocean, but are also seen above clouds and mountains. Green flashes may also be observed at the horizon in association with the Moon and bright planets, including Venus and Jupiter. [15] [16]
Much light gets reflected at the surface, and red light gets absorbed in the top few metres. Yellow and green light reach greater depths, and blue and violet light may penetrate as deep as 1,000 metres (3,300 ft). There is insufficient light for photosynthesis and plant growth beyond a depth of about 200 metres (660 ft). [42]
1. Living in the open ocean rather than coastal or inland waters (e.g. a pelagic shark). 2. Taking place in the open ocean (e.g. pelagic fishing, pelagic sealing). pelican hook. Also called a slip-hook or Davey hook. A hook with a hinge in the curve of the hook, normally held closed by a metal ring that keeps the two hinged parts together.
Water molecules can vibrate in three different modes when they interact with light. The red, orange, and yellow wavelengths of light are absorbed so the remaining light seen is composed of green, cyan, and blue wavelengths. This is the main reason the ocean's color is cyan. The relative contribution of reflected skylight and the light scattered ...
