waters.
11.5 Summary
The investigated site of the Gulf of Gdansk furnishes significant information about
the palaeogeography and water level in this part of the Baltic Sea during the very
early Atlantic period.
IntheGulfofGdansk at depths of 16-17 m, remains of alder forest dated to
8,000-7,920 years BP (9,020-8,600 calendar years) occur indicating that the water
level in the southern Baltic Sea at that time was lower, at least 17 m below the
present one.
Palynological and diatomological studies show that the investigated area was
swampy, often flooded by river and sometimes by storm surges as well.
According to dendrological investigations, the trees did not die at the same time,
so the termination of vegetation was probably caused by few river floods rather than
by marine transgression.
Results of palaeoecological investigation confirm earlier known seismic and geo-
logical evidences that a large area of the Vistula Delta was submerged by the Baltic
Sea transgression during the Atlantic period.
