Cold Deep-Sea Conditions

Project Title

Work and Performance in Cold Deep-Sea Conditions


The main objectives of this project were to establish the mechanisms accounting for the decrements in human work performance and recovery during high pressure and cold exposures in deep-sea work, to measure human breath holding times with face immersion in various water temperatures, and to explore whether there are gender differences in cognitive and psychomotor performance decrements during inert gas narcosis in cold, high pressure undersea conditions. It was hoped that the results from this project would be of assistance in developing emergency breathing systems for underwater helicopter egress and in making recommendations for Canadian and international safety standards for deep-sea diving.
