Description :
Diatom assemblages and organic carbon records from 2 sediment cores located within an estuarian bay of the inner Kara Sea trace changes in Yenisei River runoff and postglacial depositional environments. Paleosalinity and sea-ice reconstructions are based on modern relationships of local diatom assemblages and summer surface-water salinity. Approximately 15,500 cal yr B.P., rivers and bogs characterized the study area. The results show the short-term variability in riverine discharge, paleosalinity, and ice conditions in the seas of the Eurasian arctic shelf.
