Through the Archimedes principle, Physics says that the deeper an object submerged in water is, the more negatively buoyant it will get. But the change from one density to a drastically different one in just a few inches or centimeters strongly affects diver’s buoyancy.
Suddenly the surrounding water is much more dense and neutral buoyancy becomes positive. Trying to descend becomes very difficult unless some air is released from the BCD or wing. On the way back up the opposite occurs. Some air has to be added in the BCD to compensate for the decreased density in the water holding the diver. What is a halocline.
what is a halocline, Even the most seasoned divers get amazed by this effect the first time they experience it. Diving in jelly would be an accurate definition of what a diver can see when crossing the halocline. Being below it is also a trick for the eyes.
When untouched, the point where the two different waters meet looks perfectly flat, giving the optical impression of being the surface.

What does the term halocline mean?
halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
Why does a halocline form?
A halocline is also a layer of separation between two water masses by difference in density, but this time it is not caused by temperature. It occurs when two bodies of water come together, one with freshwater and the other with saltwater. Saltier water is denser and sinks leaving fresh water on the surface.
Where are Haloclines?
Haloclines are common in water-filled limestone caves near the ocean. Less dense fresh water from the land forms a layer over salt water from the ocean. For underwater cave explorers, this can cause the optical illusion of air space in caverns. Passing through the halocline tends to stir up the layers.
What is the halocline between oceans?
Border Between Two Worlds—and a World of Its Own Along that gradient, the density of the water goes from that of normal seawater to very high, and the oxygen concentration drops from normal seawater concentrations to zero. That transition zone is called the halocline.
What is an example of halocline?
Other common occurrences of haloclines are the water-filled limestone caves that are near the ocean. The less denser fresh water from the land forms a layer over the salt water from the ocean.
How do you identify halocline?
As the water is being poured or after it has been poured, for some amount of time, a hazy interface of salt layer can be easily seen. This hazy salty layer is the halocline. It becomes visible because of the varying refractive index across the boundary.
What is halocline in estuary?
Halocline is the vertical zone in oceanic water column where concentration of salinity changes rapidly relative to depth. Salinity affects the density of seawater, which can affect the vertical stratification of the seawater.

What is a halocline, The visual effects created by this layer is one of the biggest features of some of the cenotes in the Riviera Maya, such as Jardín del Eden, also known as Ponderosa.
In order to enjoy these effects being one of the first groups in the water makes a huge difference. When diving cenotes in the Riviera Maya ask your dive shop or guide to go as early as possible.
