Table 4. Total (SNO) and biological (SNOB) seasonal net outgassing (x 1014 mol O2) based on the weighted global regression coefficients for the ice-free surface oceanic domain. Atmospheric calibrated values for this work were calculated by multiplying the O2 fluxes poleward of 30 latitude by 1.09 and 0.97 in the Northern and Southern Hemispheres according to the scaling factors listed in Table 3. We also list the SNOB values of Najjar and Keeling [2000; thereafter in the table as NK00]. To obtain atmospheric calibrated values, Najjar and Keeling [2000] multiplied their O2 flux data poleward of 30 latitude by 1.15 and 1.23 in the Northern and Southern Hemispheres according to the scaling factors listed in Table 3.
