Lake Ladoga as part of Ancylus Lake (between 9300 and 9200 yr BP).WikiMatrix WikiMatrix
8000 years ago following the Ancylus Lake stage and preceding the Littorina Sea stage.WikiMatrix WikiMatrix
The predecessor to what later became the Baltic Sea, the Ancylus Lake, was formed.WikiMatrix WikiMatrix
During the Ancylus Lake subsequent regression, around 8,800 BP Ladoga became isolated.WikiMatrix WikiMatrix
Subsequently, it was a bay of Yoldia Sea and then became connected to Ancylus Lake, discharging from the north end of its extent.WikiMatrix WikiMatrix
Towards the end of its history the level of the Ancylus Lake was falling following the formation of a new outlet at the Great Belt.WikiMatrix WikiMatrix
The Bay of Bothnia was under ice until the "Ancylus Lake" period (7500–6000 BC), when the ice sheet withdrew to the mountains of Northern Scandinavia.WikiMatrix WikiMatrix
As a result of thawing inland ice, the underlying land rose and the hollows filled with water; the predecessor of what became the Baltic Sea, Ancylus Lake emerged.WikiMatrix WikiMatrix
In the stratigraphy of Baltic sediments the Mastogloia stage is difficult to detect, its sediments being visibly identical to those of the Ancylus Lake (Donner 1995, Eronen 1983).WikiMatrix WikiMatrix
Around 9000 BP Ancylus Lake, another stage of the Baltic Sea, retreated, and many lowland lakes were also isolated in depressions formed earlier by glacial exaration and fluvioglacial activity.WikiMatrix WikiMatrix
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.WikiMatrix WikiMatrix
Between 9,500 and 9,100 BP, during the transgression of Ancylus Lake, the next freshwater stage of the Baltic, Ladoga certainly became part of it, even if they hadn't been connected immediately before.WikiMatrix WikiMatrix
As geological bores near Prora in the middle of the spit have shown, the waves of the Ancylus Lake had already laid an 11 metre thick layer of sediment that was later increased again by a further 10 metres by the Litorina Sea.WikiMatrix WikiMatrix
Deposits of the Littorina Sea, on the other hand, show a drastic change both in the visible characteristics of the sediment and its diatom content (Donner 1995, Eronen 1974) One could thus argue for the inclusion of the Mastogloia Sea stage in the Ancylus Lake stage.WikiMatrix WikiMatrix
About 9,000 years ago, a meltwater lake, the Ancylus Lake, was formed, whose surface lay no higher than 8 metres below the present-day level (Normalnull), but after a period of about 1,000 years this drained, rapidly at times, into the world's oceans, which led to a renewed mainland phase, the Ancylus transgression.WikiMatrix WikiMatrix
It has been noted that a separate Mastogloia stage is useful in maintaining the clarity of the system, delimiting the period with undeniable if slight marine influence following the fall of the Ancylus Lake to sea level that predates the profound changes at the beginning of the Littorina Sea stage (Eronen 1983).WikiMatrix WikiMatrix
At that stage the Danish Straits were closed and the current Baltic Sea was the fresh-water Lake Ancylus.WikiMatrix WikiMatrix
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) Many researchers have been unwilling to recognize the Mastogloia Sea as a separate stage in the development of the Baltic Sea, favouring including it in either the Ancylus Lake stage or the Littorina Sea stage (Hyvärinen et al. 1988, Miettinen 2002).WikiMatrix WikiMatrix
Other examples include the Tethys Ocean and Ancylus Lake.ParaCrawl Corpus ParaCrawl Corpus
