WebIt is calculated by subtracting the measured in-situ oxygen concentration from the concentration in equilibrium with the atmosphere at the sea surface. AOU = NAEC – O2in situ. The units are in mol/kg. The NAEC of oxygen at 10 degrees is 280 mol/kg; 280-90 = 190; So AOU is 190 mol/kg. http://ocean.stanford.edu/courses/bomc/chem/lecture_07_qa.pdf
