Alexander P Lisitzin & Vladimir M Kuptsov
Sedimentation rates and bottom sediment ages were determined by 14C method in the Kara Sea and the Yenisei River marginal filter. Age of carbon supplied by the Yenisei River is estimated to be 6.9 ka. As supplied carbon mixes with young biogenic carbon under influence of plankton and benthos young carbon flux (planktogenic) sharply diminishes. This has been inferred from studies of organic matter in sedimentary traps deployed along sections from the Yenisei River mouth...
