Results of Paleoclimate Studies

Application of physical and biostratigraphic methods enabled establishing short-term climatic fluctuations in the Late Pleistocene and Holocene in the Arctic latitudes. It is still impossible now to reconstruct their succession and scale. Nevertheless, some of them are of great interest, since they give an idea about the high climate dynamics stemmed from migration and influence of different air masses as well as the ocean level fluctuations. As noted above, the macrofauna records the short-term invasions of the Arctic waters into the paleoshelf areas immediately after and before the Boreal transgression. The invasions brought about climatic coolings. Similarly, invasions of the Atlantic water caused the short-term warmings.
