Diatoms in the Holocene sediments of the Dvina Bay (White Sea) as indicators of paleooceanological events

Abstract

The small inland White Sea, located in the western part of the vast shallow Eurasian Arctic shelf, is a key area for detailed reconstruction of the degradation of the latest Scandinavian ice sheet. In this work we aim to reconstruct the environmental history of the Dvina Bay inferred from diatom assemblages and a radiocarbon (AMS 14C) dating. In core 6042 we found diatoms in sediments since the first half of the Preboreal.
