Almost always warmer at the surface.
Thermal Layer
The water that forms far below the surface is called a Deep Current.

Fog may form as much colder air moves over warmer ocean surface water. As the ocean evaporates into the colder air, it saturates the air producing fog that looks like streamers rising off the water.
Ocean water off the Antarctic coast is between 32F degrees and about 27F degrees, based on the salinity of the water. It's always warmer in the ocean water than it is above the surface of the water.
Stream like movements of water that occur near the surface of the ocean are called surface currents. Stream like movements of ocean water far below the surface are known as a deep current.
Deep currents are streamlike movements of water that flow very slowly along the ocean floor. Deep currents occur when the cold, dense water from the poles sinks below warmer, less sense ocean water and flows towards the equator.

When the light from the sun touches the surface of the water in oceans, the water absorbers the heat in the rays from the sun. Due to ice melting their is more water and it traps more heat inside the water making the oceans warmer and warmer.
no. Ocean temperature is not uniform with depth or surface coordinates. Tom Clancy's novel, Hunt for the Red October, describes the phenomenon of thermocline; the novel is a great read too. The ocean surface that is facing the sun in the Tropics is a lot warmer than the surface in the Antarctica. The water temperature near a undersea volcano vent is the hottest of all.
