Operation of a cheap underwater house

Abstract

1. Two divers have been maintained satisfactorily at a depth of 10,7 m for a week by means of a cheap and simple underwater house. 2. The house was unaffected by heavy seas, indicating that underwater houses can be used in exposed sites. 3. A simple closed-circuit system of air purification was used for the first time in an underwater house. © 1967 Biologischen Anstalt Helgoland.
