Test of Redfield's Model for Oxygen-Nutrient Relationships Using Regression Analysis.

摘要

Multiple regression analysis was applied to oxygen, phosphate, and nitrate data from stations in the Atlantic and Pacific Oceans. The 95% confidence intervals for delta O2 : delta PO4 and delta O2 : delta NO3 ratios were consistent with Redfield's model. Thus, the variation of O2-PO4 and O2-NO3 slopes with depth, latitude, and time is due to mixing between different water types with different preformed portions of oxygen, phosphate, and nitrate.
