Scientists used to explore【31】the surface of the ocean. Now they【32】below the surface, too. They want to know about the ocean water and the【33】and animal life【34】in the ocean.
In 1934 the scientist William Beebe dived 3 , 000 feet below the surface in a hollow steel ball. In 1935 Auguste Piccard dived 10, 330 feet. In 1960 his son Jean dived to a【35】of 35, 800 feet.
All these early dives were deep. But the divers could not stay down for very long. They had to【36】the surface after a few seconds. Scientists needed to stay down longer to study life below the surface.【37】, they succeeded. Cousteau, a Frenchman, was able to【38】down to a depth of【36】feet for one month and to a depth of 90 feet for a week.
Now scientists are developing even【39】equipment. With this new equipment, men can stay【40】the surface for days or【41】weeks. In 1962 Consteau【42】a research station 35 feet below the surface. Then in 1964 he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate【43】help from the surface.
Many countries are now studying undersea【44】. The Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet【45】on the ocean floor【46】the Virgin Islands. In 1970 five men lived there for two weeks. Then a【47】of five women scientists stayed in the laboratory.【48】came other teams of men. All were there to explore the ocean depths and【49】plans for the use of its resources. Scientists hope to find enough【50】, vegetable, and animal wealth there to provide food for the whole world.
