Abstract : The increased need for divers to operate from nuclear submarines has drawn attention to the purity of submarine air for use by divers. A review of the literature on submarine atmospheres leads to a serious concern about CO2 and a lesser concern about other inorganic, hydrocarbon, and halocarbon gases. A survey of yearly records of the levels of 14 gases obtained from 32 submarines demonstrates substantial variation among boats, and time-to-time variation within a single boat. Laboratory analysis of 21 submarine air bank samples obtained from a single boat over a 6 month period reinforces the concern for CO2, and shows measurable levels (0.1 ppm) of at least 8 other organic gases.
