The review includes, for the first time, information published in Russian-language journal articles (n = 37), and is accompanied by a new Geographic Information System (GIS) numerical age . Weichselian glaciation, climate and vegetation composition have been the focus of innumerable studies (e.g. recessive) of the Poznań phase of the Vistulian Glaciation (Weichselian) and, as a consequence, the lithostratigraphic separation of this phase from the Leszno phase of the last glaciation within the so-called Vistula lobe (Fig. READ PAPER. (2001) and Mangerud (In press). marginal positions of the Weichselian Glaciation especially in Brandenburg are located well to the north of the maxi-mum extent of previous glaciations (Fig. An ice sheet was developed over the entire Eurasian High Arctic so that ice flow from the central Barents and Kara seas toward the northern Russian Arctic could be accounted for. The following 4 files are in this category, out of 4 total. An alternative Weichselian glaciation model, with special ... Weichsel Glacial Stage | paleontology | Britannica ), 2009. It is the aim of this work to 39, pp. Kalm, V., Laumets, L. & Hang,T. As in central North America, tills and other deposits are well known only from the last part of this interval. 471-491. 1) and well apart from each other (Fig. In the southern part of Svalbard there are also indications of an overestimation of the extent of the Late Weichselian glaciation. Prentice et al., 1991; Reitalu et al., 2015; Stebich et al., 2015). Hence, this area is particularly suitable for geochronometrical studies, because the assign- After this the ice fronts receded both to the east and west. An inverse approach to modeling was utilized, where ice . A database consisting of radiocarbon (14 C), optically stimulated luminescence (OSL), thermoluminescence (TL) and beryllium (10 Be) dates was used for timing the advance of the Late Weichselian Scandinavian Ice Sheet (SIS), determining the age of the Last Glacial Maximum (LGM) and the rate of deglaciation.The study area encompasses the southeastern sector of the last SIS between the Baltic Sea . Model time is from 250 kyr BP until the present. The colder Antarctic environment is more in analogy with the maximum phase of the Weichselian glaciation. This book is the first of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. In order to reconstruct the palaeo-glaciation in Fennoscandia during the last (Weich- selian) ice age, simulations with the dynamic/thermodynamic ice-sheet model SICOPOLIS are carried out. Ice-sheet dynamics and climate fluctuations during the Weichselian glaciation along the southwestern Baltic Sea coast In the Middle Weichselian, glaciers may have begun to advance during the early part of oxygen isotope stage 4 (ca. In the southern part of Svalbard there are also indications of an overestimation of the extent of the Late Weichselian glaciation. The model's main features are as follows. Evidence suggests that the ice sheets were at their maximum size for only a short period, between 25,000 to 13,000 BP. Pleistocene Glaciations of Southern Germany .

RECENTLY, Boulton and Worsley1 have interpreted the huge composite morainic suite which occurs in the Wrexham-Bar Hill area of the Shropshire-Cheshire Basin as an end-moraine marking the . The deglacial history generally is similar, except for a widespread but short interval… Blake (1981) has resolutely rejected this idea. Nature - <ArticleTitle Language="En" xml:lang="en">Late Weichselian Glaciation in the Cheshire-Shropshire Basin</ArticleTitle> The Early Weichselian in neighbouring regions The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago), and is ongoing. 63,000 yr bp. A regional glaciation model for the Weichselian is based on new data from the Mezen Bay area and previously published data from adjacent areas. The Late Weichselian glaciation (MIS 2) deposited a thin till cover, which was partly eroded by fluvial processes during the last deglaciation. This paper. Terrestrial and marine records show that ice volumes fluctuated drastically during the Weichselian. Dated marine This map shows Europe during its last glaciation, about 20,000 to 70,000 years before present, in northern Europe called Weichselian Glaciation, in the Alpine Region Würm Glaciation.

(Weichselian) Glaciation are widespread across most of Lithua - nia. The final occurrence of Elphidium ustulatum (Todd) has been noted; this is a foraminiferid that became extinct in the North Sea by the early Weichselian (Gregory and Bridge, 1979). Geological constraints on ice-sheet deglaciation are essential for improving the modelling of ice masses and understanding their potential for future . The youngest succession (A) comprises units 5 and 6, and reflects fiord glaciation followed by a regression during an Early Weichselian glaciation-deglaciation episode. In current study the behaviour of the SIS during . Oxygen isotope stage 3 (OIS 3) was a mild interval between the two cold maxima of the last (Weichselian) glaciation marked by climate changes oscillating on a 100-1000 yr time scale between near-interglacial and peak-glacial conditions. Weichselian glaciation, is located in the Augustów district of the Podlasie Province (Fig. The Late Weichselian glaciation is most extensively studied; however chronological data are unevenly distributed and the timing of the advance of the last SIS and its arrival to maximum extent and deglaciation are continuously debated. 1). This information is seen as a fundamental requirement, not only for the glacial workers, but for the wider user-community of general Quaternary workers. (1984) hypothesis on the possible age of a Weichselian glaciation prior to 36 ka BP, this paper will bring new information of regional significance from key sites in the 182 Bulletin of the Geological Society of Denmark . In particular, this account focuses on the last cold stage, the Weichselian, with its extensive Late Weichselian glaciation and the subsequent deglaciation, and on the last 10,000 years, the Holocene, with its well documented environmental changes. It is the aim of this work to Cli- matic forcing is based on present distributions of mean annual surface temperature and precipitation over the region, which are derived from the NCEP . Boulton (1979a, p. 52, 1981) has suggested that this was restricted to a short event about 11 000 years B.P. The model indicates complete glaciation of the Barents and Kara seas and predicts a "maximum-sized" ice sheet for the Late Weichselian Russian High Arctic. Ice Drift, Ocean Circulation and Climate Change is the first book to focus on the interactions between ice, the ocean and the atmosphere and to describe how these three components of the climate system influence each other. of the Weichselian glaciation. Weichselian glaciation (Scandinavia and northern Europe) Europe during the last glacial period. Geological processes caused by the Weichselian glaciation and the changes in continental, lacustrine and marine environments over last 14 500 years have played an important role in relief formation and sediment distribution [18]. However, many proper - ties of till are of uncertain origin and this hinders correlation of The ages of the three groups indicate deposition of all the preserved moraines during the Late Weichselian glaciation. Long and continu-ous records from the deep sea and from the Greenland Weichselian glaciation refers to the last glacial period and its associated glaciation in northern parts of Europe.In the Alpine region it corresponds to the Würm glaciation.It was characterized by a large ice sheet (the Fenno-Scandian ice sheet) that spread out from the Scandinavian Mountains and extended as far as the east coast of Schleswig-Holstein, the March of Brandenburg and Northwest . marginal positions of the Weichselian Glaciation especially in Brandenburg are located well to the north of the maxi-mum extent of previous glaciations (Fig. 37 Full PDFs related to this paper.

The possibility that ice-free areas existed during the late Weichselian glaciation of the Svalbard archipelago has been debated for several decades. Results of a complex study (OSL and 14C AMS datings, pollen, diatom and ostracod data) on the Late Saalian to Holocene sediment sequence at Arumetsa, southwestern Estonia, are reported by M. Rattas and These are presented in an am-ple series of papers in Boreas, 28, (1-3), 1999, in which, after descriptions of field evidence and laboratory results, the principal conclusions are given, collectively referred here as "the QUEEN model". …of the last glaciation, the Weichselian and Devensian, correlate with oxygen-18 stages 5d-a, 4, 3, and 2. Boulton (1979a, p. 52, 1981) has suggested that this was restricted to a short event about 11 000 years B.P. 471-491. The mean age of 13.7 ± 1.3 ka was calculated based on two exposure ages obtained on the Pras3 . 3, pp. The last glacial period and its association glaciation is known in Northern Europe and northern Central Europe as the Weichselian glaciation, Weichselian ice age (German: Weichsel-Eiszeit), Vistulian glaciation, Weichsel or, less commonly, the Weichsel glaciation, Weichselian cold period (Weichsel-Kaltzeit), Weichselian glacial (Weichsel-Glazial), Weichselian Stage or, rarely, the Weichselian . This has necessitated the revision of the chronological data. Keywords Iceland, vegetation, glaciation, refugia, palaeobotany. Using the radiocarbon dates an isochron map was drawn which indicated areas of refugia off the west coast of the British Isles, south-west Scandinavia and in south-western Europe.

An uncertain Early Weichselian ice limit is a line interpolated between known stratigraphic sites using such signatures of former glaciation as occurence of buried bodies of stratiform massive ice in the lowlands of West Siberia and/or assemblages of ice-pushed ridges in higher terrains. Support is provided for previous reports of two sets of shorelines on NW Spitsbergen, the oldest (at 60 m in St Jonsfjorden) dating to a pre-late Weichselian glaciation . Geological constraints on ice-sheet deglaciation are essential for improving the modelling of ice masses and understanding their potential for future . Basal temperature conditions reflect long term changes and are thus more influenced by the Many ISSN 0300-9483. A revised lithostratigraphy of Skåne, South Sweden, constitutes the basis of an alternative Weichselian glaciation model for southern Scandinavia, progressively anchored to the stratigraphy. The symposium was a onset of the Late Weichselian glaciation in northern continuation of the tradition of annual meetings of Finland took place about 22-25 ka ago. Boreas, Vol. Larsen & Sejrup (1990), Houmark-Nielsen (1999), Sejrup et al. Still, the occurrence of Early to Middle Weichselian glaciation in this region remains controversial because the advancing ice sheet has a great destructive potential for soft unconsolidated sediments and most of the sediments of former . Skåne was not glaciated during the Weichselian until 21,000 B.P. Weichselian Ice Sheet. During the ice-free period preceding that glaciation, at least back to 40,000 yr B.P., the glaciers on Svalbard were not significantly larger than at present, as shown by marine deposits close to the glacier snouts. The main objective of this thesis was to examine the paleoenvironment and glaciation history of the Weichselian (MIS 5-2) and the late Saalian (MIS 6) stages in northern and west-central Finland. Alternative names include: Weichsel glaciation or Vistulian glaciation (referring to the Polish River Vistula or its German name Weichsel). This glaciation phase was terminated by a deglaciation phase at approximately 54,000 yr bp. Chronology of the Weichselian Glaciation in the southeastern part of the Scandinavian Ice Sheet.

Although geologists describe the entire time period as an "ice age", in popular culture the term "ice age" is usually associated with just the most recent glacial period during the . Evidence suggests that the ice sheets . 39, pp. the late Weichselian glaciation was short, certainly less than 10,000 years. The term "Wisconsinan Glaciation" refers to the last major glacial episode that affected North America, more properly referred to as the Wisconsinan Stage (Black et al., 1973; Fulton, 1989; Clark and Lea, 1992) (Figure W1).The term should be restricted to the deposits and events of the Laurentide Ice Sheet (LIS; see Laurentide Ice Sheet), which extended from the Canadian Arctic coast to . The INQUA Peribaltic Working Group Field Symposium in southern Estonia and northern Latvia, September 13-17, 2009. The Weichselian Cold Stage (Weichselian Glaciation) is usually divided into the Early (Lower) Weichselian (M IS 5d-5a), Middle Weichselian (MIS 4 and 3) and Late (Upper) Weichselian (MIS 2) Substages.

Due to their good preservation, the Veiki moraine provides valuable information . (1993). During the last age, ending about 20,000 years ago, glaciers extended over much of northrn Europe and also over much of Canada and some of the northern United States. 1). The heavy minerals were analysed for 36 samples of sandy deposits. This conclusion is supported by recent palaeoclimatic data from ice-cores and deep-sea sediments, indicating that Icelandic climate during the last glacial was only occasionally slightly colder than during the Younger Dryas stadial. In particular the need for accurate ice-front positions is a basic requirement . The first recorded marine inundation is found in the Fladen area where marine sedimentation started close to 22 ka BP. The ice remained cold in analogy with the present Greenlandic Ice Sheet. isostatic response. Abstract. Three sample sets from the Pras1 and Pras2 moraines yield a mean exposure age of 17.9 ± 1.5 ka and 15.7 ± 0.6 ka, respectively. Blake (1981) has resolutely rejected this idea.

A survey was made of all existing radiocarbon dates relating to the Corylus rise in Europe in order to find the possible areas of refugia of Corylus during the Weichselian glaciation. In southern Norway, the Eemian is now thought to have been succeeded by a prolonged period of interstadial conditions with restricted mountain glaciation (Sejrup et . 14.1. 14.3. In the region of the Lower Vistula there is evidence on separateness of the above . The concepts, outlet surge and marginal dome (the main tools of the model) are defined. 14.4.

In a period between 29.4 and c. 22 ka BP, the northern North Sea experienced its maximum Weichselian glaciation with a coalescing British and Scandinavian ice sheet. Weichselian contact have been described, and that the onset of the Late Weichselian glaciation in northern Finland took place about 22Œ25 ka ago. Two tills in Hyvinkää represent one Weichselian glaciation: the lower till, named the Tanssikallio Till, being a basal lodgement till formed during the initial stage of the last Weichselian glaciation, and the upper till, named the Hyvinkää Till, being a basal melt-out till from the time of the deglaciation of southern Finland, before the formation of the first Salpausselkä .
