Geosphere Interactions On A Convecting Planet: Mixing and Separation

On Verdansky's biosphere

“…The value of the total biomass of the living matter in the biosphere given by Vernadsky, 5.1 × 10 20 grams (1924a, p. 281) or in order of 10 20 -10 21 g (1924a, p. 262, 1925a § §2-3, 1929 and 1997a §46), is of the same order of mass of the free oxygen in the biosphere, 1.5 × 10 21 (Vernadsky 1924a(Vernadsky , pp. 49-50, 1925a A.1 §7), and comes near of that of the Earth, 6 × 10 27 g (Fyfe 1992). However is valuation is relativelly higher than that of other authors: actually ca 5 × 10 18 g of fresh biomass, and ca 18,41 × 10 17 g of dry biomass (Taube 1992) (12.9 × 10 17 g, according to Duvignaud 1980).…”
