 During the dive, Beebe peered out of a porthole and reported his observations by telephone to Barton who was on the surface.In 1948, Swiss physicist Auguste Piccard tested a much deeper-diving vessel he invented called the bathyscaphe, a navigable deep-sea vessel with its gasoline-filled float and suspended chamber or gondola of spherical steel.On an experimental dive in the Cape Verde Islands, his bathyscaphe successfully withstood the pressure on it at , but its body was severely damaged by heavy waves after the dive.
