Nothing very exciting happens because as the cold water would rise it would push the warm water down. This would cause the cold water to heat up and the warm water to cool off. This creates a cycle of cooling and warming.
The process is called Upwelling.

Upwelling in biology is the process in which nutrient rich soil that is located deeper in the ocean rises to the surface due to ocean currents and winds. This is important because it allows the organisms living at the surface to get their needed nutriends
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
