Grain-size of varved clays from the north-eastern Baltic Ice Lake: Insight to the sedimentary environment

Estuarine, Coastal and Shelf Science, 2017
Abstract Besides providing high resolution chronological information, varved sediments also are excellent environmental archives. We examined the grain size distribution of varved glaciolacustrine sediments as a proxy for estimation of the water depth and the duration of winter – a period with diminished sediment input from the melting glacier and ...

Evidence of the final drainage of the Baltic Ice Lake and the brackish phase of the Yoldia Sea in glacial varves from the Baltic Sea

Boreas, 2002
A clay‐varve chronology based on 14 cross‐correlated varve graphs from the Baltic Sea and a mean varve thickness curve has been constructed. This chronology is correlated with the Swedish Time Scale and covers the time span 11 530 to 10250 varve years BP.

Allerød‐ Younger Dryas sea level changes in southwestern Sweden and their relation to the Baltic Ice Lake development

Boreas, 1991
Mt. Kroppefjall is situated just south of the Middle Swedish (Younger Dryas) ice‐marginal zone. Its abundance of lake basins makes it very suitable for detailed shore displacement studies close to the Younger Dryas ice margin. Altogether 12 lakes at altitudes between 157 and 78 m were studied and all but one situated above the marine limit contained ...

The Baltic Ice Lake and Yoldia sea stages, based on data from diatom analysis in the central, south-eastern and eastern Baltic

Quaternary International, 1995
Abstract This paper is the first attempt to summarize the results of diatom analyses from sediments of Late Glacial and Preboreal age in the central, south-eastern and eastern Baltic. The Baltic Ice Lake deposits are poor in diatoms and amongst those present planktonic freshwater species dominate.

Ice cover determination of the lakes of Baltic and White sea basins on the base of Jason-2 satellite observations

2014 IEEE/OES Baltic International Symposium (BALTIC), 2014
Thy work aims to development of a simple method for distinction between open water and ice cover on the base of geophysical data record (GDR) of altimetry satellite Jason-2 for large and middle-sized freshwater inland water bodies. The method is applied to the lakes of Baltic and White Seas basins: Ladoga, Onega, Vygozero and Segosero.

Depositional evidence of water-level changes of the Baltic Ice Lake in southern Finland during the Younger Dryas/Holocene transition

GFF, 2011
Two natural clay sections were described from southern Finland. The sites, Jokela and Koria, are located 5-10 km south of the 1st Salpausselka end moraine. Six sedimentary units were identified and interpreted: (1) Baltic Ice Lake (BIL) varved sediments – interbedded, laminated clay and silt with load structures and sand layers in places; (2 ...

Late Weichselian marine stratigraphy of the southern Kattegat, Scandinavia: evidence for drainage of the Baltic Ice Lake between 12,700 and 10,300 years BP

Boreas, 1992
From stratigraphic investigations of 38 piston and vibro cores, four fine‐grained Late Weichselian sediment units can be defined in the southern Kattegat. A continuous stratigraphic record of the Late Weichselian sediments cannot be established from single cores due to the uneven distribution of the units, but by compilation of relative stratigraphies ...

Varve chronology on Södertörn: Recording and dating of the “drainage” of the Baltic Ice Lake and correlation with the Finnish varve chronology

Geologiska Föreningen i Stockholm Förhandlingar, 1977
Abstract Short-distance varve correlations across the Sodertorn area have extended the continuous Swedish Time Scale back to about varve -1500 (about 10,400 B.P.). Varve -1073 (= 9,965 varves B.P.) is represented by a distinct drainage varve and a change from diatact to symict varves, recording the “drainage” of the Baltic Ice Lake at Billingen and the
