A series of 6-hour test dives were accomplished to determine the gas consumption rates of divers breathing air from an open circuit demand system for rest, light exercise, and moderate exercise at water temperatures of 40F, 60F and 80F. Diver dress was the wet suit. The results indicate a significant increase in gas consumption in 40F water for the rest and light exercise activities. The 40F moderate exercise and all exercise levels at 60F and 80F produced values close to those predicted in the U.S. Navy Diving Gas Manual. Only two divers out of six were able to complete the 40F, 6-hour dive.
