dc.description.abstract During a series of three saturation dives performed at the U.S. Navy Experimental Diving Unit, experiments were undertaken to compare the CO2 scrubbing characteristics of two new Mark 11 CO2 absorbent canisters with the standard canister configuration, and to investigate the ability of each system to support sustained, heavy work in cold water to depths of 650 FSW. Canister duration studies were performed on the three CO2 absorbent canister configurations at depths of 450 and/or 650 FSW. When compared to standard MK 11 canister performance, the central heated core configuration with Koegel valves (FC 979A) demonstrated markedly longer canister duration at 450 FSW, but only slight improvement at 650 FSW. However, work of breathing and inspired gas temperatures were greatly improved at both depths. The triple pass canister configuration demonstrated improved duration but unacceptably high breathing resistance. Other life support characteristics such as thermal protection, inspired gas temperature, and PO2 were adequate to depths of 650 FSW. en_US
