Why does sea appear bluish?

Expert Answer
The sea isn't always blue, however. Some seas appear bluish-green or green or brown or even red. These colorations are partly due to the reflection of clouds, but are caused mainly by various particles, mineral or organic, that are in suspension in the water. In some areas, especially along coastlines and in shallower seas, organic matter decomposes and produces a yellow pigment that when mixed with blue light makes the sea appear bluish-green.
