“…In northern Germany the ice sheet reached its maximum extent at~22 ka BP (e.g. HoumarkNielsen et al, 2003;Sommer and Benecke, 2009;Houmark-Nielsen, 2010;Ukkonen et al, 2011). The observed sedimentary succession of waterlain sediments capped by subglacial till is consistent with ice advance, and the two~23 ka are within error and in agreement with the regional geochronology.…”

“…Retreat of the Scandinavian Ice Sheet and development of icefree conditions in northern Germany and Denmark after 29 ka BP was followed by renewed growth of the Baltic ice streams to their maximum limits between 25 and 22 ka BP (Houmark-Nielsen and Jørgensen and Piotrowski, 2003;Larsen et al, 2009;Sommer and Benecke, 2009;Houmark-Nielsen, 2010;Ukkonen et al, 2011), terminating some 50 km to the south and 25 km to the west of the study area. Stratigraphic investigations have identified five glacial fluctuations during this expansion, the first four of which took place south of the study area, which remained ice covered (Stephan and Menke, 1977;Stephan et al, 1983;Prange, 1987Prange, , 1990.…”

a b s t r a c tSubglacial lakes are common features of contemporary ice masses. However, they are rarely identified in the geological record. This is due to the difficulty in discriminating between subglacial and proglacial lake sediments; a proglacial origin is typically preferred as the 'simplest' explanation. We hypothesise that numerous deposits currently interpreted to record proglacial lake sedimentation may actually have a subglacial origin. Here we try and find ways of distinguishing proglacial from subglacial lake sediments by investigating three sites along the D€ anischer Wohld Peninsula, northern Germany, which have been interpreted to record both proglacial and subglacial sedimentation. We identify two major phases of ice activity and associated lake formation during the Late Weichselian glaciation. (1) Proglacial lake formation at~23 ka in front of the advancing Baltic Ice Stream. This lake was subsequently overridden and the sediments glaciotectonised as ice continued to advance to its maximum extent. (2) Retreat of ice back into the Baltic Basin at~19 ka and formation of a proglacial lake that persisted for~4 ka. We suggest that subglacial lake activity may have occurred at two of the sites between 23 and 19 ka. This is based on the presence of aggrading sediment deposits characterised by stratified/laminated diamictons and interbedded tabular to channelized sorted sediments, the juxtaposition of relatively undeformed waterlain sediment and subglacial till, absence of glaciotectonic thrusting and folding or of fining/coarsening successions and the geomorphic association with tunnel valleys to the south of the study area. The style of sedimentation and deformation provided the greatest insight into the discrimination of proglacially vs subglacially deposited glaciolacustrine sediments. The luminescence signal palaeodose distributions also offers a potentially powerful means of fingerprinting sediment transport pathways of young glacial systems.

“…The 14 C dates are calibrated into calendar ages using IntCal13 (Reimer et al, 2013). The calendar ages are reported in cal ky BP and correlated with cold phases (Greenland Stadials, GS) and warm phases (Greenland Interstadials, GI) (Shackleton, 1977;Hedges et al, 1998;Litt et al, 2001;Gibbard and van Kolfschoten, 2004;Andersen et al, 2006;Chabai and Uthmeier, 2006;Gerasimenko, 2006;Svensson et al, 2006Svensson et al, , 2008Mol, 2008;Velichko and Faustova, 2009;Rasmussen et al, 2014 For this study we used a large amount of published data on fossil mammoth remains from different parts of Eurasia (Vereshchagin, 1979;Vereshchagin and Baryshnikov, 1985;Musil, 1985;Kahlke, 1994Kahlke, , 2014Kahlke, , 2015Vartanyan et al, 1995;Ukkonen et al, 1999Ukkonen et al, , 2007Garrut and Tikhonov, 2001;Foronova, 2001;Lister and Sher, 2001;Lougas et al, 2002;MacPhee et al, 2002;Stuart et al, 2002Stuart et al, , 2004Kuzmin et al, 2003;Kosintsev, 2003;Rustioni et al, 2003;Tong and Patou-Mathis, 2003;Kuzmin and Orlova, 2004;Sher et al, 2005;Stuart, 2005;Takahashi et al, 2007;Sommer and Benecke, 2009;…”

a b s t r a c tBased on geographic information (database PALEOFAUNA), in combination with 14 C and other methods of paleo dating (1584 localities, 4033 dates, including 1501 direct dates), we first examined details of changes of mammoth distribution in Eurasia on the whole and in single parts of the range over the last 50ky. The analysis of regional features in the dynamics of mammoth range and the quantity of dated localities acknowledged a leading role of the climatic (environmental) factor in these processes. The maximum size of the Eurasian range, the largest number of remains of mammoths from dated localities and, probably, the maximum total number of population were established for the range of 38.2 e8.6 cal ky BP (Denekamp interstadial ¼ Bryansk interstadial). In Western and Central Europe, the increase of population was observed during Huneborg stadial (40.8e38.2 cal ky BP). In eastern Siberia, the maximum population growth occurred in the Last Glacial Maximum (28.6e22.5 cal ky BP), and in Western Siberia e during Deglaciation (22.5e14.7 cal ky BP). The population dynamics at the periphery of the range (Islands of Japan, British Isles, Northern Europe, Southern Siberia and Northern China, and, but to lesser extent, South-Eastern Europe) differs from the dynamics of its main part. The southernmost parts of the range e Southern Siberia and southeastern Europe experienced similar changes. Population dynamics in the Iberian Peninsula was much alike the changes in Western and Central Europe. We suggested that some peripheral populations could periodically be isolated from the populations of the main part of the range. Direct calibrated radiocarbon dates fixed upper boundary of extinction of this species in different parts of range within time interval from 21 (the Iberian Peninsula) to 4 (northeastern Siberia) thousands years BP. The hypotheses about the causes of the dynamics of the area and population of the mammoth in Eurasia, including those related to the extinction of certain genetic lines of a mammoth in the Late Pleistocene, are being discussed.

We present a new time-slice reconstruction of the Eurasian ice sheets (British-Irish, Svalbard-Barents-Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from 25 to 10 ka, and at four selected time periods back to 40 ka. The time-slice maps of ice-sheet extent are based on a new Geographical Information System (GIS) database, where we have collected published numerical dates constraining the timing of ice-sheet advance and retreat, and additionally geomorphological and geological evidence contained within the existing literature. We integrate all uncertainty estimates into three ice-margin lines for each time-slice; a most-credible line, derived from our assessment of all available evidence, with bounding maximum and minimum limits allowed by existing data. This approach was motivated by the demands of glaciological, isostatic and climate modelling and to clearly display limitations in knowledge. The timing of advance and retreat were both remarkably spatially variable across the ice-sheet area. According to our compilation the westernmost limit along the British-Irish and Norwegian continental shelf was reached up to 7000 years earlier (at c. 27-26 ka) than the eastern limit on the Russian Plain (at c. 20-19 ka). The Eurasian ice sheet complex as a whole attained its maximum extent (5.5 Mkm 2 ) and volume (~24 m Sea Level Equivalent) at c. 21 ka. Our continentalscale approach highlights instances of conflicting evidence and gaps in the ice-sheet chronology where uncertainties remain large and should be a focus for future research. Largest uncertainties coincide with locations presently below sea level and where contradicting evidence exists. This first version of the database and time-slices (DATED-1) has a census date of 1 January 2013 and both are available to download via the Bjerknes Climate Data Centre and PANGAEA (www.bcdc.no;
