Photo of the Day : Seawater With Different Colors

Seafarers get an opportunity to see some of the best natural phenomena in the world which land-dwellers can’t. Some of these are so special that it is best to capture them through lens to preserve that moment for life.

Once such phenomena was captured by 3rd Officer Rahul Gupta when he was sailing from Arabian Sea to Persian Gulf. It was an amazing sight of seawater with two different colors. The color seemed to change at a certain boundary, giving a sense of two different water bodies which decided not to blend together.

Though he didn’t know the real reason for the same, it would have been a waste not to capture that scene. Here’s a pic of the seawater with two different colors captured through the lens of the 3rd Officer.

According to wikipedia,

 ”The “color” of the ocean is determined by the interactions of incident light with substances or particles present in the water. White light from the sun is made up of a combination of colors, which are broken apart by water droplets in a ‘rainbow’ spectrum. When light hits the water surface, the different colors are absorbed, transmitted, scattered, or reflected in differing intensities by water molecules and other so-called optically-active constituents in suspension in the upper layer of the ocean. The reason open ocean waters often appear blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water. In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue. Almost all sunlight that enters the ocean is absorbed, except very close to the coast. The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean. When sunlight hits the ocean, some of the light is reflected back directly but most of it penetrates the ocean surface and interacts with the water molecules that it encounters. The red, orange, yellow, and green wavelengths of light are absorbed so that the remaining light we see is composed of the shorter wavelength blues and violets.”
Moreover, according to another explanation, algae growths are also responsible for the various different water colors. In the Red Sea, there is an algae bloom that creates red of the water. Algae also creates the green hue of the Colorado River in the Marble Canyon during the spring. Other parts of the Colorado River have a red tone due to sediment in the water.

No matter what the real reason is, this beautiful scene was aptly captured at the right time.
