What happens if you swim to the bottom of the ocean?

How cold is it at the bottom of the ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
What is at the bottom of the ocean?
