Because water is not perfectly transparent,almost all sunlight is absorbed in the surface layer,which heats up.Wind and waves circulate the water in the surface layer,distributing heat within it somewhat,and the temperature may be quite uniform for the first few hundred feet.Below this mixed layer,however,the temperature drops very rapidly—perhaps as much as 20 degrees Celsius with an additional 150 m (500 ft) of depth.This area of rapid transition is the thermocline.
Below the thermocline,the temperature continues to drop with depth,but far more gradually.In the Earth's oceans,90% of the water is below the thermocline.This deep ocean consists of layers of equal density,being poorly mixed,and may be as cold as 0 to 3 °C.
In the open ocean,the thermocline has been important in submarine warfare,because it can reflect active sonar.
