Life Support Characteristics of the Mark 11 Semi-Closed Mixed Gas Underwater Breathing Apparatus at Intermediate Depths

Abstract

A series of three saturation dives designed to evaluate the ability of the Mark 11 UBA to support a working diver in its normal semi-closed mode of operation were performed at the Navy Experimental Diving Unit. Experiments were undertaken to determine the life expectancy of Mark 11 C02 removal canisters in several configurations, and to investigate the ability of the system to support sustained, heavy work in cold water to depths of 450 FSW.
