What general statement Can you make about the change in temperature as you go deeper in Earth's ocean?

Generally, the temperature of Earth's oceans decreases as you go deeper.

Explanation:

Sunlight as well as the atmosphere may be seen as the prime reasons for the surface of the oceans to be a higher temperature than at deeper depths. The question specifically includes the word generally to allude to the idea that geothermal vents (as well as other features) can result in small sections of the ocean or ocean floor to even be a higher temperature than the surface, even though they are found much deeper.
