Why do the colors of sea water vary around the world

Arab Weather - Who among us has not been fascinated by the beauty of the clear blue sea water, and the charming turquoise color of the waters of the Caribbean Sea near the islands, but your feeling about the color of the sea water may change if you see the stormy sea in a dark gray color, while many people think that the sea water is only blue, However, there is some variation in the color in which the sea water can appear around the world, so what creates such variation in the color of the sea water?

Water appears in all bodies of water on Earth in a certain color based on a number of factors, but before we talk about these factors and the diversity of colors in water bodies around the world, we will take a quick look at the nature of light and how it interacts with the natural world.

Water and light

When we see something with a specific color, we actually see a wavelength of light that is not absorbed by the body and reflected back to our eyes. Natural light is made up of all the colors of the visible spectrum, but most of the wavelengths are absorbed, while one color is reflected back to our eyes.

For example, when sunlight passes through our atmosphere , the short wavelengths of blue light are more easily dispersed, giving the sky its distinctive blue color, as other colors are absorbed more easily by their reflection.

Water is naturally colorless, but it does not appear colorless if a large amount of water such as water meets in bodies of water from seas and lakes , and when natural light interacts with a water body, water molecules absorb most of the wavelengths in red, orange, green and yellow, and the wavelengths of color are reflected. Blue again, which gives that water its blue color, but why is the degree of color different or how blue it is?
