P.135 right column 3rd paragraph: "The world oceans have, on the one hand, a relatively small oxygen content which is 1/120 (Tab. 2) of that of the atmospheric oxygen reserve. But on the other hand, the oceans have a very large interface with the atmosphere, amounting to 70 % of the earth's surface and a primary productivity which ranges from 30 to 300 g C/m^2/yr (primary source Berger et al., 1989). Despite the fact that the oceans only contain 0.22% of the world's biomass, their primary productivity is in great measure due to a much more rapid turnover of the oceanic biomass, viz., 54 % of the world primary production (cf. Tab. 2 and Taube, 1992)." |
