“…That age is supported by AMS dates from the Tõdva basin (Fig. 2) beyond the Palivere zone where sedimentation started about 13 200±140 cal yr BP (Saarse et al, 2012b). Estimated by OSL (Raukas & Stankowski, 2005) and 10 Be methods (Rinterknecht et al, 2006) ages of the Palivere belt sediments differ thousand of years and does not give reliable age for this belt.…”

and was used to create a GIS-based palaeogeographical reconstructions on the development of the Baltic Ice Lake (BIL). The formation of the highest shoreline of the BIL in Estonia was connected with the development of the Pandivere ice marginal zone (Estonia) and the lowest with the Salpausselkä ice-marginal formations (Finland). There was a well-accepted knowledge that the Pandivere ice marginal zone correlates with the Neva ice marginal zone in NW Russia dated to 13 300 cal yr BP. Recent studies of the late glacial sites in northern Estonia indicate that the age of the Pandivere ice marginal zone and hence the highest shoreline of the BIL A 1 is about 13 800-14 000 cal yr BP. It was followed by the BIL stage A 2 , which formed in front of the Palivere ice marginal belt about 13 200-13 500 cal yr BP. The final drainage of the BIL took place about 11 650 cal yr BP. The timing of the BIL stages was derived from AMS-14 C dates and correlated with varve chronology, OSL and 10 Be dates.

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;

“…However, there is often visually a distinct transition from mineral deposits to organic carbonrich gyttja and/or autochthonous carbonate precipitate sediment accumulation since the onset of the warm Holocene throughout Estonia, except in the lowland areas which were flooded by the waters of the Baltic Sea basin. Correspondingly in Estonia, fossil pollen and macrofossil evidence at the lateglacial/Holocene transition shows abrupt vegetation response in tandem with the climatic changes -the predominantly open tundralike ecosystem declined and was replaced by pine (Pinus) and birch (Betula) dominated forests (Saarse et al 2009(Saarse et al , 2011Amon et al 2010Amon et al , 2012Amon et al , 2014Kihno et al 2011;Feurdean et al 2014;Stivrins et al 2016). Pollenbased climate reconstructions suggest a distinct increase in all re constructed climate variables around and shortly after 11 700 cal yr BP, e.g.…”

Over the past 25 years since the ratification of the last official Holocene Stratigraphic Chart in Estonia, the stratigraphic framework of global Quaternary geology has significantly progressed. The Pleistocene/Holocene boundary is defined in the NGRIP2 ice core from Greenland, with an age of 11 700 calendar yr b2k (before AD 2000). The International Subcommission on Quaternary Stratigraphy developed a formal tripartite stratigraphical subdivision of the Holocene into the Greenlandian, Northgrippian and Meghalayan stages/ages, each supported by a Global Boundary Stratotype Section and Point (GSSP). All three GSSPs are defined on the basis of geochemical markers reflecting abrupt global climatic events dated with high accuracy and serving as a reliable foundation for cross correlation. In the light of this development we present a new formal subdivision for the Holocene in Estonia. The new chart is climatostratigraphic with tripartite subdivision. The chronological boundaries and corresponding names for the stages/ages are aligned with the International Holocene Stratigraphic Chart. The correlation is achieved using synchronous and significant global climatic oscillation events, preserved in Estonian Holocene sedimentary proxy archives. The correlation relies on the direct dating of these Holocene sedimentary successions, particularly AMS 14 C dating, lake sediment varve counts, etc. The subdivision of the Baltic Sea sediments in the new Holocene stratigraphic chart is based on the internationally recognized stages in the Baltic Sea history and the chronology of their boundaries. Longterm traditions in geoarchaeological studies in Estonia require a common understanding of the chronological background. Therefore, the subdivision of the Estonian Prehistoric period was included in the new Holocene Stratigraphic Chart of Estonia which was approved by the Estonian Commission on Stratigraphy on 15 January 2020.
