What's the reason behind being different colour(of water) of different ocean

the objects close to the observer appear as their real color, whereas the objects further away appear to be blue. The blueness of water is very apparent when diving. As one goes deeper, lower energy wavelengths penetrate the water less, eventually leaving only blue light from the higher energy end of the spectrum.......


The surface of seas and lakes often reflect blue skylight, making them appear bluer. The relative contribution of reflected skylight and the light scattered back from the depths depends strongly on the observation angle. In this view of Crater Lake (Oregon, USA), the far side of the lake reflects the sky more, and the near side shows mostly the actual water.

As one goes deeper, lower energy wavelengths penetrate the water less, eventually leaving only blue light from the higher energy end of the spectrum. Even when using an artificial light source, such as a flash, the objects close to the observer appear as their real color, whereas the objects further away appear to be blue.

It has to do with the depth of the water and the quality of sunlight as well as any change in the colour of the ocean bottom. A large part of the blue colouring of water is a reflection of the sky.

Not a reason, there are some reasons:
- The sea bottom
- The depth of sea water
- The water compositions (minerals, creatures living inside, is that transparent...)
As you have seen why they call "Black Sea", "Red Sea"...

-
The depth of the water. Shallow water is lighter.
The temperature of the water. Colder water has less algae that make the water look green.
