- | This stratification in lakes also leads to the well-known effects of oxygen depletion in deep water, since diffusion is limited through the distinct strata.

In saline water (salinity > 1000 ppm) water is in its densest form when below zero degrees. However, salinity and the temperature and pressure distributions determine the level of stratification. Stratification occurs when water masses with different properties form different small layers (<30m thickness) whose density increase with depth. These layers act as barriers to water mixing. The different properties of the water include salinity and temperature, | In saline water (salinity > 1000 ppm) water is in its densest form when below zero degrees.
