Robert Stanberry, aged 11, of Emmett, Idaho for his question:

How deed can a deep sea diver go?

This depends upon the kind of clothes and equipment the diver is wearing. Many deep sea divers have walked on the ocean floor 60 feet below the surface. These experts need diving helmets and weighted shoes. With a more complicated equipment it is possible to walk on the ocean floor 500 feet below the surface. But this equipment is so heavy that the diver cannot do much when he is down there, He also needs oxygen. Expert divers can go no deeper than this in a suit ‑ or out of one.

However, certain people have gone deeper into the ocean. They have descended in specially built little rooms. One of these deep sea chambers is called the bathysphere. It was let down off the coast of Bermuda in the year 1934. In it Willam Beebe and Otis Barton descended 302 feet below the surface of the sea.

In 1949, William Barton went even deeper. He used an underwater chamber called the benthosphere. The benthosphere was let down off the coast of California. In it Barton descended 4500 feet below the surface of the sea. The Bathscaphe Trieste § has reached the great depth of 35,802 ft. (10,912 meters).
