Abstract: Basing on statistical analysis of ca. 150 radiocarbon dates of sediments from different environments an attempt to reconstruct the time framework of main environmental changes during the late Pleistocene and Holocene in the Southern Baltic area was made. The main results are as follow: - 45 000-22 000 years BP - period of interpleniglacial (Grudziadz Interstadial), - 22 000-14 500 years BP - period of the last glaciation (lack of dates for this period or uncorrected dates), - 14 500-8800 years BP - beginning of the last deglaciation and development of the southern Baltic area in land conditions, - 8800-5000 years BP - period of Mezoholocene (Littorina, Atlantic) transgression of the Southern Baltic with major changes of coastline, - since ca. 5000 years BP - present shape of the southern Baltic with minor changes of coastline.
Key words: radiocarbon dates, Pleistocene, Holocene, Polish coastal zone, Southern Baltic
