Changes of sea level, landscape and culture: A review of the south-western Baltic area between 8800 and 4000 BC

The global warming at the end of the last glacial period led to a sea level rise, which induced substantial long-term landscape changes in the southwestern Baltic Sea. During the Preboreal and Boreal periods, this region, bordering on the Ancylus Lake in the east, was dry land with numerous lakes and rivers. However, with the beginning of the Littorina Transgression around 6700 BC, during the Atlantic period, the area became connected to the ocean. People settling along the coast of the former Ancylus Lake, Mesolithic hunter–gatherers, continuously had to adapt to rapid changes. ttorina Transgression made a new source available to man: the young Baltic Sea. Important settlement sites were founded in the coastal regions, and were consumed one by one by the constantly rising sea level. At the time of the decline of the sea level rise and the beginning consolidation of the coast lines, a socially motivated turn towards a productive economy started. Hunting and fishery were widely replaced by agriculture and stock farming. erstand the interplay between all of these developments, it is necessary that scientists from a variety of disciplines undertake collective investigations. This paper presents first culture-historical, palaeozoological, palaeobotanical, palaeoecological and palaeogeographical results yielded by from the multidisciplinary research group SINCOS (Sinking Coasts) and uses these to create a new comprehensive picture of the development of the south-western Baltic Sea region during the Ancylus Lake and Littorina Sea stages.
