First underwater observation chamber

Last updated: September 20, 2017 at 1:46 am

The Calypso was the first ship equipped with an underwater observation chamber with 6 portholes where a person could view sea life from a depth of 3 m (10 ft) in 1950. The chamber was replaced by a larger but lighter design including 8 portholes in 1966.
