Comments P.135 right column 3rd paragraph: "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 primary source)."
