Why is the ocean blue?

In effect, the ocean is not blue. The water simply reflects the color of the sky overhead (which appears to us as blue -- due to refraction of incoming light). Of course, ocean water contains much particulate matter, but this does not cause the "blue" color.

Hope this helps!

Actually, all colors of light enter the water and the yellow and red light is absorbed in the upper part of the water and only the green and blue spectrum of light remains to be seen by the eye. The ocean is blue because it does not contain particulate matter to change it to another color. Coastal oceans are grren because of the microalgae (phyto-plankton) and because of organic conpunds like those that leak out of soil that are yellow. If you dive under the water and look around, you will seee that everything looks blue because no yellow or red light can penetrate that deep and be reflected from objects and thus seen by the eye.
