Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean , while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1 ]
Glacial rock flour makes New Zealand's Lake Pukaki a lighter turquoise than its neighbors. The presence of color in water does not necessarily indicate that the water is not drinkable. Water with high water clarity is generally more cyan in color due to low concentrations of particles and/or dissolved substances. Color-causing particulate ...
The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
Since liquid water flows, ocean waters cycle and flow in currents around the world. Since water easily changes phase, it can be carried into the atmosphere as water vapour or frozen as an iceberg. It can then precipitate or melt to become liquid water again. All marine life is immersed in water, the matrix and womb of life itself. [7]
A lake in Westgate Park, Melbourne, Australia, was coloured pink in March 2017 [10] and then again in September 2019, but since then and as of January 2022 had taken on a dark green hue. Warmer weather and lower rainfall appears to make it turn pink. [1] As water evaporates, the salinity increases, but salinity is not the only factor at work.
A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...

At an approximate depth of 30 feet (9.1 m), red is no longer visible to the naked eye. At 75 feet (23 m), yellow looks greenish-blue, because the water has absorbed the yellow light. Finally, all that remains visible to the naked eye, appears as a mutation of blue or green, while the water above the surface filters out the sunlight.
