Parameter Derivation Significance
Oxygen saturation The ratio (as a percent) of measured oxygen concentration to the oxygen concentration of water at equilibrium with the atmosphere is based on potential temperature and salinity. Air-sea oxygen flux.
Apparent oxygen utilization (AOU) The deviation of the measured dissolved oxygen from the theoretical solubility of oxygen at the measured temperature and salinity. Sum of biological activities in terms of consumption / production of oxygen.
