“…This is supported by dates indicating advance across Poland after 25–29 ka (Pazdur et al . ), western Latvia after c. 26 ka (Saks et al . ; Lasberg & Kalm ) and central and southern Lithuania after c. 25 ka (Lasberg & Kalm ).…”

“…The maximum line for the southern SIS is placed close to the Brandenburg and Leszno moraine positions in Germany and western Poland, respectively (Pazdur et al . ; Lüthgens & Böse ; Böse et al . ; Marks ), but evidence suggests that the ice front did not advance into Denmark until the following stage (Houmark‐Nielsen & Kjær ; Houmark‐Nielsen ).…”

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;

“…The ANU Sucrose Secondary Radiocarbon Dating Standard was used as the modern reference standard, correlated with 95% of 14C activity of NBS Oxalic Acid, normalized to 3130 = -19%o wrt PDB, according to Polach (1979) and Currie and Polach (1980). Laboratory equipment and techniques have been described (Pazdur et al, 1982;1983), the only exception being chemical pretreatment of peat samples. Unless otherwise stated, peat samples were pretreated only with HCI, as suggested by Hakansson (1976).…”

The following list contains all age measurements of paleoenvironmental samples made from 1978 to the end of 1982 for the IGCP 158 Project “Paleohydrological changes in the temperate zone in the last 15,000 years,” Subproject B “Lake and mire environments” (Berglund, 1979), initiated by Bjorn Berglund and Leszek Starkel in 1976. The aim of this project was to reconstruct environmental changes related to climate and human activity in the temperate zone of Asia, Europe, and North America. Broad environmental reconstructions will be based upon a network of reference sites representing the natural geographic regions, distinguished by their geology, climate, vegetation, and other natural factors, according to Berglund (1979). The subdivision of Poland into 29 paleoecological units according to Ralska-Jasiewiczowa (1982) is presented in table 1, and in figure 1 where reference sites dated by 14C in our lab are also indicated.
