Resumo: 	Oxygen concentrations were measured at discrete depths (0 to 250 m) at 20-day fixed station in an oligotrophic area (Proligo cruise of R/V Jean Charcot , 15 degree S, 173 degree E, September-October 1985). Measurements are available for both early morning and evening over a period of 14 days. Daily oxygen production is very variable, and does not permit a precise estimation of photosynthetic carbon fixation. Empirical orthogonal function analysis shows that the variability of the oxygen concentrations is null at the surface, increases evenly downwards, reaches a maximum at the depth of the nutricline and at the deep chlorophyll maximum, and decreases to null values at 187 m depth. Absence of a pronounced daily periodicity of the oxygen concentration is attributed to horizontal advection and mesoscale variability.
