Water is blue ... because water is blue

One of the most appealing aspects of the ocean is the colour of the water, ranging from a greyish green to deep blue. But wait a minute: When I pour water in a glass, it is a clear, transparent liquid. So, what is the cause of the blue colour of the sea? Is it the reflection of the blue sky, perhaps? The answer is simple, and perhaps surprising: Water is blue, because water is blue.

Technical explanation ahead.
