“…Indeed, the early stage of Baltic Sea filling occurred at ca. 16-15 ka (11,23), which lends support to the concomitant disappearance of water pulses observed in the BS (15.7 ± 0.3 ka) (16).…”

Continental ice sheets are a key component of the Earth's climate system, but their internal dynamics need to be further studied. Since the last deglaciation, the northern Eurasian Fennoscandian Ice Sheet (FIS) has been connected to the Black Sea (BS) watershed, making this basin a suitable location to investigate former icesheet dynamics. Here, from a core retrieved in the BS, we combine the use of neodymium isotopes, high-resolution elemental analysis, and biomarkers to trace changes in sediment provenance and river runoff. We reveal cyclic releases of meltwater originating from Lake Disna, a proglacial lake linked to the FIS during Heinrich Stadial 1. Regional interactions within the climate-lake-FIS system, linked to changes in the availability of subglacial water, led to abrupt drainage cycles of the FIS into the BS watershed. This phenomenon raised the BS water level by ∼100 m until the sill of the Bosphorus Strait was reached, flooding the vast northwestern BS shelf and deeply affecting the hydrology and circulation of the BS and, probably, of the Marmara and Aegean Seas.ice dynamics | meltwater routing | European hydrographic network

“…Upham, 1895; Leverett, 1902). The routing of lake overflows and meltwater is important because of the potential impact on ocean circulation and climate (Rooth, 1982;Teller et al, 2002;Barber et al, 1999;Spielhagen et al, 2004;Mangerud et al, 2004;Carlson and 18 Clark, 2012). However, the discharge and location of water overflowing from these lakes varied as ice retreated from various basins, thereby opening new outlets (Teller and Thorleifson, 1983;Teller, 1987;Smith and Fisher, 1993;Smith, 1994;Mangerud et al, 2001;.…”

“…The landscape-forming processes in the study region probably pertained to a more comprehensive reorganisation of the hydrological systems in northern Eurasia. For example, Mangerud et al (2004) have reported on the rerouting of the drainage in northern Eurasia during this period connected with changing orientation of glacial meltwater runoff.…”

a b s t r a c tLate Quaternary palaeoenvironments of the Siberian Arctic were reconstructed by combining data from several fossil bioindicators (pollen, plant macro-fossils, ostracods, insects, and mammal bones) with sedimentological and cryolithological data from permafrost deposits. The record mirrors the environmental history of Beringia and covers glacial/interglacial and stadial/interstadial climate variations with a focus on the Middle Weichselian interstadial (50-32 kyr BP). The late Pleistocene to Holocene sequence on Kurungnakh Island reflects the development of periglacial landscapes under changing sedimentation regimes which were meandering fluvial during the Early Weichselian, colluvial or proluvial on gently inclined plaines during the Middle and Late Weichselian, and thermokarstaffected during the Holocene. Palaeoecological records indicate the existence of tundra-steppe vegetation under cold continental climate conditions during the Middle Weichselian interstadial. Due to sedimentation gaps in the sequence between 32 and 17 kyr BP and 17 and 8 kyr BP, the Late Weichselian stadial is incompletely represented in the studied outcrops. Nevertheless, by several palaeoecological indications arctic tundra-steppe vegetation under extremely cold-arid conditions prevailed during the late Pleistocene. The tundra-steppe disappeared completely due to lasting paludification during the Holocene. Initially subarctic shrub tundra formed, which later retreated in course of the late Holocene cooling.
