Littorina Sea

It is a former lagoon of the prehictoric Littorina Sea.

There are also several lakes, that are former lagoons of the Littorina Sea.

The modern topography was shaped by the glacier retreat some 12,000 years ago which created the Littorina Sea.

Due to steady post-glacial rebound it became connected with the mainland during the early Littorina Sea stage.

Retreat of the Ice Age glacier formed Littorina Sea.

The lake became Littorina Sea when rising oceanic levels broke through the Great Belt.

At the end of that time rising Kattegat levels broke into Ancylus lake, creating Littorina Sea.

This took place ca. 8000 years ago following the Ancylus Lake stage and preceding the Littorina Sea stage.

These animals for the most part were common in the Littorina Sea but are not found in the Baltic Sea now.

Others prefer to include it in the Littorina Sea stage as a transitional phase after the establishment of the marine connection (Hyvärinen et al. 1988).

The arrival of markedly brackish conditions marks the beginning of the Littorina Sea stage (Miettinen 2004).

Humans began to inhabit these places soon after the ice age glaciers have retreated and the water level of the Littorina Sea lowered to reveal the land.

During the Littorina Sea transgression an island archipelago was formed by the carving of narrow glacial basins and channels resulting from meltwater.

Its retreat formed Littorina Sea, which water level was some 7-9 metres higher than the present level of the Baltic Sea.

Littorina has given its name to the Littorina Sea, the geologic precursor of the Baltic Sea.

In the north of the Karelian Isthmus, the Littorina Sea united by a wide strait with Lake Ladoga.

Hypoxic conditions were common during the development of the early Baltic Sea called the Littorina Sea starting around 8,000 calendar years BP.

The Littorina Sea was a period of transgression and maximum salinity during the warmer Atlantic period of European climatology.

The Littorina Sea is named after common periwinkle (Littorina littorea), then a prevailing mollusc in the Baltic waters, which indicates salinity of the sea.

The Ancylus age is followed by formation of the Littorina Sea and the Litorina Stage (named after the Littorina littorea mollusc) at around 6200 BC.

Late in the Atlantic, Kongemose culture settlements were abandoned due to rising water of the Littorina Sea and the succeeding Ertebølle culture (5400-3900 BC) settled more densely on the new shorelines.

The Littorina Sea - with the rise in sea level and the submergence of the Øresund strait, the Baltic again communicated with the North Sea beginning 7,800 ΒP to present.

In places the shoreline forms sea cliffs that were formed thousands of years ago by breakers in the Littorina Sea, when the islands of Wittow and Jasmund were still not linked by the Schaabe.

Littorina Sea (also Litorina Sea) is a geological brackish-water stage of the Baltic Sea, which existed around 7500-4000 BP and followed the Mastogloia Sea, transitional stage of the Ancylus Lake.

The Mastogloia Sea stage thus constitutes a transitional phase between the freshwater Ancylus Lake stage and the Littorina Sea stage during which the Baltic was clearly brackish (Donner 1995, Hyvärinen et al. 1988)
