| Abstract: | The compositional changes and frequency variations in the foraminiferal communities through the sediment section across Dvina
Bay allow us to identify 14 ecological-stratigraphic zones. Based on the 14C dates for the foraminiferal tests, the distinguished ecozones correspond to the appropriate Holocene stages and substages.
Because most of the foraminiferal species identified in the Holocene sediments are abundant and diverse in the modern oceans,
they provide a powerful tool for the reconstruction of the paleoenvironmental changes during the Holocene. |
