Fig. 30. Comparison of amounts of organic carbon (/), fine sediment fraction (//), and benthos biomass (///) in bottom soils of Barents Sea along cross sec- tion from 75° 50' N latitude and 25° 00' E longitude approximately along 74° parallel towards coast of Novaya Zemlya. (IV) Depth, m (Gorshkova, 1958). bottom life. However, in the northern parts of the sea on soft brown sedi- ments life is scarce and the amount of organic matter low. Finally, many regions with sandy bottoms and a rich life may have a low content of organic matter. Good vertical and horizontal water circulation prevents the accumula- tion of organic matter on the bottom, sweeping it again and again into a vortex. Hence, although on one hand one may accept the rule that seas rich in life have more organic matter in their soils, in some of them a reverse relationship between the amount of bottom life and of organic matter in the sea-bed may be created. The comparison of benthos biomass and carbon content in the sea-bed, given in Fig. 30, may serve as an illustration of this. The picture of the relationship between the biomass density and the carbon content of the sediment may also be obscured by the quantitative distribution of plankton and its role in the formation of organic matter in the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability
