Recorded in the Atlantic Ocean from Harbor Branch Oceanographic. Otis Barton joins the Johnson Sea Link Sub Crew for a commemorative dive. Barton was a pioneer underwater explorer and the designer of the bathysphere (1930). This recording is one of four that documents the conversation between Barton and the other diver during the dive. The view is solely of inside the submersible and of the two men. The bathysphere was designed by underwater explorers Otis Barton and William Beebee and took its first plunge in 1930. A bathysphere consists of a steel sphere with small circular windows of fused quartz. Inside it are the required oxygen tanks. During dives, these vessels were lowered into the water with cables and chains. During its first year, the bathysphere design could already dive to depths of 1,426 feet, two years later breaking records at 3,028 feet. Many discoveries about the deep sea were made from the confines of these vessels.
