The top is warmed by the sun's rays. Warm water is less dense than cold water so if floats on top. As water cools it sinks to lower levels...until it reaches the bottom.
a surface current is warmer becasuse it isn't near the bottom of the ocean its near the top so it gets more heat
At the top of the ocean, or Sunlit, It is warmer because the top of the ocean the sun is closer then it is to the twilight,dark,abyss, and trenches zone. At the bottom of the ocean, or Trenches, It is colder because the sun can not reach that low in the ocean better then it can the Sunlit zone.
The bottom of the ocean is colder. The sun heats the top of the ocean first and then heats lower. In a nutshell, the top of the ocean is warmer and the deeper you go the colder.

The ocean floor
Clown fish live at the bottom of the sea in sheltered reefs or in shallow lagoons. They live in the warmer waters of the Pacific Ocean and Indian Ocean
Bottom, because cold water is denser.
bottom
The sun is not as close to the bottom of the ocean as it is at the top.
The opposite of bottom would be the top, so the oceans surface is the opposite of the ocean floor/bottom.
It goes from the top of the globe to the bottom from about the Atlantic Ocean.
