The same water in a smaller bucket looks only slightly cyan, [1] and observing the water at close range makes it appear colorless to the naked eye. The intrinsic color of liquid water may be demonstrated by looking at a white light source through a long pipe that is filled with purified water and closed at both ends with a transparent window.
Water in the open ocean appears clear and blue because it contains much less particulate matter, such as phytoplankton or other suspended particles, and the clearer the water, the deeper the light penetration. Blue light penetrates deeply and is scattered by the water molecules, while all other colours are absorbed; thus the water appears blue ...
A deep blue colored wave viewed from the water surface near Encinitas, California, United States. The Pacific Ocean contains some of the most deep blue colored waters in the world. The reason that open-ocean waters appear blue is that they are very clear, somewhat similar to pure water, and have few materials present or very tiny particles only.
How clear the water appears is only one component of water quality. [1] [5] [47] An underwater ecosystem can have high water clarity yet low water quality, and vice versa. Scientists have observed that many lakes are becoming less clear while also recovering from acid rain. This phenomenon has been seen in the northeastern United States and ...

The footage is so clear that you can easily spot the little squid’s two eyes — one large and one small. Read on to learn how the strawberry squid benefits from its unusual set of eyes.
Scientists have solved the 200-year-old mystery of the location of a massive volcanic eruption that spewed such a large volume of gases that it blocked sunlight, making the sun appear blue.. The ...
The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times.
