Foraminiferal analysis of sediments of Holocene in the Baltic and Kattegat Seas has been carried out. It was found that these deposits contain euryhaline benthic foraminifera along with stenohaline planktonic species typical for the North Atlantic. Growth of concentrations of the first and appearance of the second unambiguously indicate a more intensive penetration of saline water from the North Sea into the Baltic Sea. This allows to use foraminifera for stratigraphic analysis of deposits of the Baltic Sea. More rich and various fauna of benthic foraminifera in the Kattegat Sea allows also to reconstruct the characteristics and dynamics of bottom and surface water masses, circulated between the Baltic and North Seas.
