Four U.S. Navy first class divers, a Medical Officer, and a civilian laboratory technician were compressed to a simulated depth of 600 feet of sea water in the Duke University Hyperbaric Complex. During the subsequent 7 days at 600 feet, two warm 90F and 5 cold 43-49F water experiments were conducted in order to assess the performance of the Mark IX semi-closed circuit UBA at depth. From these tests, it was concluded that the Mark IX could safely support a hard working diver in cold water at 600 feet, although the thermal sensitivity of the carbon dioxide canister limited the useful duration of the apparatus. In addition, the importance of heating the inspired gas during deep dives in cold water was noted. Author
