Abstract : Despite recent scientific and technological gains in realizing the goal of manned underwater stations, there has been a singular lack of research data on defining the sleep requirements of man-in-the-sea. Behaviorally, sleep loss and sleep disturbances produce lapses in performance and impairment of short-term memory, wither of which may endanger the mission or the life of the entire crew of an ocean floor habitat. Interpersonal difficulties may also arise as a result of undesirable personality changes caused by sleep disturbances, thereby weakening the very root of the miniature society of the ocean floor habitat. Research efforts must be spurred on to learn: (1) whether man as an aquanaut may develop new kinds of sleep requirements which differ from those of land based man, (2) whether man may also develop serious sleep disturbances, whether we can specify the optimal physical and psychological conditions for man's recuperation from fatigue by adequate sleep in the underwater habitat. TEKTITE I, a nitrogen saturation diving experiment is used to illustrate an attempt to obtain the data necessary to define sleep requirements of man-in-the-sea. (Author)
