en.wikipedia.org/wiki/Stratification_(water)

Water stratification is when water masses with different properties - salinity , oxygenation , density , temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia. These layers are normally arranged according to density, with the least dense water masses sitting above the more dense ...

Stratification of Water The vertical distribution of water density in bodies of fresh or salt water is known as stratification and is characterized by the vertical density gradient. The greater the increase in density with depth and the greater the vertical gradient, the higher the stability of the stratification. When the vertical density gradient is ...

Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia. These layers are normally arranged according to density, with the least dense water masses ...

en.wikipedia.org/wiki/Lake_stratification

The thermal stratification of lakes refers to a change in the temperature at different depths in the lake, and is due to the change in water's density with temperature. Cold water is denser than warm water and the epilimnion generally consists of water that is not as dense as the water in the hypolimnion.

To test this hypothesis we set out two bowls, one hot and one cold. The skittles in the hot bowl dissolved quicker, but the really neat thing about this experiment was that the cold water dish created a beautiful display of how heat can create water stratification. We also got lucky and caught an S floating up in the hot water dish.

How Does Stratification Affect Water Quality? COSEE Greatest of the Great Lakes—A Medley of Model Lessons. Answers Although the Eastern Basin stratifies during the summer, it does not become anoxic. This is because it is so deep. Deep waters are cold, while shallow waters are warm. Cold water can hold

A less distinct density stratification than that seen in summer develops under the ice during winter. Most of the water column is isothermal at a temperature of 4°C, which is denser than the colder, lighter water just below the ice.

PAX Water Technologies explains how water storage tanks can become thermally stratified and how active tank mixing can be used eliminate this problem.

eyecular.com/what-is-stratification

Thermal stratification is possible as water becomes less dense when heated, meaning water weighs less per unit volume. Therefore, warmer water will be lighter and colder water will be heavier. Due to this, there will always be a level of “self-induced” thermal stratification in a water storage.

Water Density. To understand lake stratification, we first must address the relationship between water density and temperature. Water is unique in that it is more dense as a liquid than a solid; therefore, ice floats.
