Recorded in Florida at Harbor Branch Oceanographic and in the Atlantic Ocean. This recording documents Otis Barton, pioneer underwater explorer and designer of the bathysphere (1930), as he revisits the deep sea 50 years later aboard the Johnson Sea Link 1. The recording includes drawings of the creatures that Barton encountered during his plunges during the era of the bathysphere. Following this, the recording goes on to another deep dive aboard the Johnson Sea Link 1 submersible. Included are close up images of the deep sea animal life collected during this dive. It is not mentioned whether or not Barton also took part in this dive. 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.
