What you say is mostly correct but the colour of the sky also plays a part, any observation of the sea on a clear day and a cloudy day shows a marked difference in colour.

haven't you ever seen green oceans before?

Answer 5

No, I don't think so. There are several factors to why the ocean has its colors. It is a common misconception that in large bodies, such as the oceans, the water's color is blue due to the reflections from the sky on its surface. This is not true, but was believed to be so decades ago. The main reason the ocean is blue is because water itself is a blue-colored chemical. Optical scattering from water molecules provides a second source of the blue color, but colored light caused by scattering only becomes significant with extremely pure water. According to the frequency spectra for pure liquid water, a short water column has a very light shade of turquoise blue. Thicker layers (many meters) appear much darker blue. It is only when collected in a large body that water's blue color becomes apparent.

Particles and solutes can absorb light, as in tea or coffee. Green algae in rivers and streams often lend a blue-green color. The red sea has occasional blooms of red Trichodesmium erythraeum algae.
