It happens in the atmosphere too, but to a lesser degree.\n\nWater (even pure water) reflects, refracts, and absorbs light.  As light passes through a body of water, some of the light is reflected back, some of the light is refracted (bent), and some of the light is absorbed (leading to warming of the water).  The more water the light has to pass through, the more of the light that is reflected, refracted, or absorbed.  So the deeper you go, the less light will reach you.\n\nTo simplify, just consider absorbsion.  If a cloumn of water one metre deep absorbs 50% of the light that passes through it, then the light at the top of the column will be 100% and at the bottom only 50%.  Add another column of one metre under the first column and it will absorb 50% of the light that passes through it.  It has 50% of the total light available at the top, so only 25% remains at the bottom.\nAnd so on.

Well the sea is blue because the blue light from the sun is refracted and the other channels of light get through.
