MAN has, in the current century, been making tremendous technicological advances, and these advances have permitted him to explore new or "exotic" environments. Examples of these explorations are the yeararound colonization of the Antarctic, the adventures into outer space, and the developing exploration of and attempts to inhabit the inner space, the oceanic subsurface. The inherent stresses man encounters in attempting habitation of the polar ice caps or outer space are items of common knowledge; the stresses encountered in man's effort to explore, inhabit, and use the "inner" space are not, however, well documented. Efforts made toward understanding and using the submarine space have been primarily military ones. This restrictiveness may be one reason for the scarcity of published material dealing with the adjustment patterns of the men who make these efforts.
My intention here is to provide observational data on one aspect
