TL;DR: In this paper, the maximum limits of the Eurasian ice sheets during four glaciations have been reconstructed: (1) the Late Saalian (>140 ka), (2) the Early Weichselian (100-80 ka),(3) the Middle Weichsellian (60-50 ka), and (4) the late Weichselsian (25-15 ka) based on satellite data and aerial photographs combined with geological field investigations in Russia and Siberia, and with marine seismic and sediment core data.
Journal ArticleDOI
Ice-dammed lakes and rerouting of the drainage of northern Eurasia during the Last Glaciation.
Jan Mangerud,Martin Jakobsson,Helena Alexanderson,Valery Astakhov,Garry K. C. Clarke,Mona Henriksen,Christian Hjort,Gerhard Krinner,Juha Pekka Lunkka,Per Möller,Andrew S. Murray,Olga Nikolskaya,Matti Saarnisto,John Inge Svendsen +13 more
TL;DR: In this article, the authors reconstructed large ice-dammed lakes with reversed outlets, e.g. toward the Caspian Sea, based on numerous optically stimulated luminescence (OSL) dates for the periods 90-80 and 60-50 ka.
Journal ArticleDOI
Maximum extent of the Eurasian ice sheets in the Barents and Kara Sea region during the Weichselian
John Inge Svendsen,Valery Astakhov,Dimitri Yu. Bolshiyanov,Igor Demidov,Julian A. Dowdeswell,Valery Gataullin,Christian Hjort,Hans Hubberten,Eiliv Larsen,Jan Mangerud,Martin Melles,Per Möller,Matti Saarnisto,Martin J. Siegert +13 more
TL;DR: In this article, the authors made a preliminary reconstruction of the maximum ice-sheet extent in the Barents and Kara Sea region during the Early/Middle Weichselian and the Late Weichsellian.
Journal ArticleDOI
The periglacial climate and environment in northern Eurasia during the Last Glaciation

TL;DR: In this paper, the results of studies of the Late Weichselian periglacial environments carried out in key areas of northern Eurasia by several QUEEN teams (European Science Foundation (ESF) programme: “Quaternary Environment of the Eurasian North”).
Journal ArticleDOI
Age and extent of the Barents and Kara ice sheets in Northern Russia
TL;DR: In this article, the authors show that the Markhida line is of Middle/Early Weichselian age, implying that no ice sheet reached this part of Northern Russia during the Late Weichselsian.
