AB: We present estimates of the climatological annual cycle of dissolved oxygen content in the upper 0 to 100 m depth layer of the world ocean. The analysis is based on data from the World Ocean Atlas 2001. The oxygen and heat contents are compared by means of Fourier analysis. The amplitude of the global oxygen and heat contents are dominated by the Pacific Basin in both hemispheres. It is shown that the extra-tropical annual oxygen and heat contents are inversely correlated. The oxygen content cycle lags the heat content cycle by a month. The decadal variability in oxygen is described for the period 1955 to 1998.
