Non-mixing water layers

Sometimes, due to the different properties of water, it is possible to visually determine the border of the joints of reservoirs and different water masses. Because of this, there may even be lakes, underwater waterfalls, and even huge underwater waves that can reach hundreds of meters in height, but they are completely invisible on the surface.

Under the influence of salinity, the water masses of the World's oceans are transformed, the thermocline is ventilated, deep convection occurs, and many other amazing phenomena occur, including the formation of salt fingers and mysterious giant lenses (an isolated object of water in the form of a lens/lentil that does not mix with the rest of the water).

Types of Water Properties Jump layers:

• Thermocline-a layer of temperature jump (divided into seasonal and deep-water. Seasonal thermocline occurs and breaks down during the annual course of temperature, for example, when ice melts or the flow of warm water into the sea increases. It is usually located at depths of no more than 200 meters. Deep water exists constantly, covering the water column up to 2000 meters. The refraction of sound in a thermocline noticeably changes its properties.)
• Chemocline-a layer of a jump in the chemical composition (a special case related to the salinity of water is called halocline. Chemocline most often occurs in places where conditions contribute to the formation of oxygen-free bottom waters — water at a depth depleted of oxygen, where only anaerobic life forms can exist. Examples of chemocline formation sites are the Black Sea, as well as a number of lakes, such as Lake of Jellyfish and Grave lake.)
• Pycnocline - a layer of density jump (is an obstacle to the passage of the sonar signal, which serves as a masking factor when the submarine evades the sonar search for surface ships, and also plays a crucial role in the life of the World Ocean. In the density jump layer (its depth ranges from 25 to 100-120 m), vertical density gradients can reach very large values, and in these cases it plays the role of the mentioned "liquid soil", on which not only planktonic, but also larger organisms can concentrate.)
