“…yr BP). This estimation is older than recently suggested (Kalm, 2012;Saarse et al, 2012;Lasberg & Kalm, 2013;Vassiljev & Saarse, 2013) and does not fit with 10 Be-based dates, which indicate that the Pandivere belt formed 13 100±1100 10 Be years BP (Rinterknecht et al, 2006). The varved clay results and their correlation with the Neva ice marginal belt (Saarnisto & Saarinen, 2001) provide grounds for estimating the age of the Pandivere stadial at 12 700 varve years (Hang, 1997), redefined to 13 300 varve years by Hang (2003) and later to more than 13 300 cal.…”

“…Ice-marginal belts mark standstills of the ice termini or small-scale readvances (Zelčs & Nartišs, 2014). To date these belts, different methods have been applied, such as optically stimulated luminescence (OSL), cosmogenic 10 Be exposure dating, varve chronology, conventional and Accelerator Mass Spectrometry (AMS) radiocarbon dating and pollen analyses (Pirrus, 1965;Pirrus & Raukas, 1996;Sandgren et al, 1997;Raukas, 2004;Raukas & Stankowski, 2005;Kalm, 2006Kalm, , 2012Kalm et al, 2011;Rosentau, 2006;Saarse et al, 2012;Lasberg & Kalm, 2013). However, the estimations of the time of the deglaciation vary notably by approach.…”

In this study, the deglaciation chronology of the Pandivere Upland is defined, and the late-glacial vegetation trends of north-eastern Estonia are summarised. The multi-proxy study includes accelerated mass spectrometry 14 C dating, plant macrofossil, magnetic susceptibility, loss-on-ignition and grain-size distribution data of the lacustrine sediment record from one previously unpublished study site (Kursi), and the study discusses the results in combination with five previously published study locations from the area.The results indicate that the deglaciation of the Pandivere Upland started at approximately 14 200 cal. yr BP and was completed by 13 800 cal. yr BP. The ice recession rate was approximately 180 m yr -1 . Based on these new radiocarbon dates, the Baltic Ice Lake stage A 1 submerged the northern and western ice-free areas of Estonia by ca. 13 800 cal. yr BP. The prevalent vegetation type in north-eastern Estonia during the late-glacial period was tundra with local variations in the dominant shrub species. The region remained treeless until the Holocene.

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;
