Deep ocean

The deep ocean is the lowest layer in an ocean, existing below the thermocline. The deep ocean is not well mixed, and consists of horizontal layers of equal density, and is often as cold as 0-3 degrees C (32-37.5 degrees Fahrenheit). Ninety percent of the total volume of Earth's oceans is found in the deep ocean.
