The Thermocline:

The layer in a body of water in which water temperature drops with increased depth faster than it does in other layers is called the thermocline. Since the sun cannot heat the ocean water under the surface directly the temperature of the water sharply decreases as the depth increases.It exists because the water near the surface becomes less dense as energy from the sun's rays warms the water. The thermocline marks the separation between warm water and the cold deep water.Below the thermocline the temperature continues to decrease but slowly.The thermocline may disappear if the temperature changes or the shifting currents or it can also change the depth of the thermocline.



Deep water :

 * In the deep zones of the ocean the temperature reaches up to **2°.It never reaches to 0 degrees because of the pressure and the ocean current movements. The colder the water is the denser it is so the deep ocean water is very dense.The deep ocean water also holds much more gas than the warm surface water. There are also barely any organisms that live in the deep ocean water but the "horrible deep sea creatures". For example, the humpback angler fish and the lantern fish. There is barely any food in the deep ocean since the suns rays don't reach it doesn't make it possible for photosynthesis.
