Multiple regression analysis was applied to oxygen, phosphate, and nitrate data from stations in the Atlantic and Pacific Oceans. The 95% confidence intervals for ΔO 2 : PO 4 and ΔO 2 : ΔNO 3 ratios were consistent with Redfield’s model. Thus, the variation of O 2 –PO 4 and O 2 –NO 3 slopes with depth, latitude, and time is due to mixing between different water types with different preformed portions of oxygen, phosphate, and nitrate.
