Comments P.130 left column 3rd paragraph: "Budyko et al. (primary source) confirmed this range of buried organic carbon as given by Degens (1982), to be equivalent to 3.68 x 10^20 mol O2 for continents, shelves, and ocean floors (Fig. 10), which is higher by a factor of 10 than the atmospheric oxygen mass." P.130 left column bottom paragraph: "Budyko et al. (primary source) presented a complete picture which is summarized in Figure 10. The part still lacking (imbalanced part of 1.92 x 10^20 mol O2) may be organic matter originating from the ocean and shelf bottom which has disappeared under the continents by subduction (personal communication of I. Foster Brown, Woods Hole Research Centre, USA, and Federal University Fluminense, Niteroi, Brazil)." P.130 right column 2nd paragraph: "A recent estimate of Keeling et al. (1993) gives a much higher value for the sedimentary rock organic matter. Their value of 1,000,000 x 10^15 (10^21) mol of organic-C is far higher than that of Budyko et al. (primary source) and as such twice the total atmospheric and "stored" oxygen of 5.63 x 10^20 mol, given in Figure 10." Please see caption beneath figure 10
