The performance of two divers working at 33 ft. on a communication dependent task was observed and measured. Comparisons between productivity and error generation using closed and open cycle breathing apparatus, as well as heliumoxygen, nitrogenoxygen and argonoxygen mixtures, were made. Measurement of oxygen uptake and carbon dioxide production during the communication task, as well as for a series of constant swim rates, was recorded. No significant difference in productivity was noted for any gas mixture or breathing apparatus used. Significant differences were noted in error generation for the heliumoxygen mixture. In addition, the distribution of errors between specific letter-number pairs and sound groups differed significantly for heliumoxygen mixtures. Oxygen uptake during the communication task was equivalent to that previously measured for self-paced work. Author
