metadata.value: Few detailed case studies have been devoted so far to the Late Pleistocene palaeogeography
  of the northern Mologa-Sheksna Lowland (MSL), compared to adjacent regions covering the
  Valdai glaciation marginal zone. Lake Beloye (Russia, Vologda region, Babaevo district) bottom
  sediments were studied using ground penetrating radar (GPR) and subsequently were
  cored in order to build a palaeoclimatic reconstruction for the northern MSL, because lacustrine
  deposits are considered to be valuable and representative palaeoarchive of the area. Chronology
  of regional palaeoclimatic and palaeohydrological changes from the Bølling — Allerød
  warming to the Early Holocene was traced on the basis of inorganic and organic geochemistry,
  mineralogical proxies, grain-size, magnetic susceptibility, accelerator mass spectrometry
  radiocarbon dating and optical microanalysis. During the Late Glacial and the Pleistocene/
  Holocene transition in the northern MSL interstadial climatic conditions were determined at
  ~ 14.0 cal. ka BP (Bølling, stage GI-1e of the GICC05 timescale) and ~ 13.0 cal. ka BP (Allerød,
  stages GI-1c3 — GI-1a). A pronounced cold period associated with Younger Dryas (stage GS-
  1) was registered in the multiproxy record at 12.8–11.7 cal. ka BP. High-resolution x-ray fluorescence
  (XRF) core scanning helped to reveal short-term “cold” events at ~ 13.7, ~ 13.1 and
  ~ 11.5 cal. ka BP, which were associated with Older Dryas (stage GI-1d), Gerzensee-Killarney
  oscillation (stage GI-1b) and Preboreal oscillation respectively, and “warm” episodes at
  ~ 13.2 and ~ 11.8 cal. ka BP, which presumably correspond to the end of the stage GI-1c1 and
  Greenlandian Stage/Age respectively. Ultimate interglacial (Holocene) climate onset within
  the MSL was attributed to ~ 11,7 cal. ka BP, which is marked by the sharp rise of total organic
  carbon content in the sediments and lithological changes to muddy fraction. Numerous water
  level oscillations occurred in the large proglacial lakeduring the last glacial termination,
  ending with Its final drainage in the northern MSL by ~ 10.9 cal. ka BP. The reconstructed palaeoclimatic
  dynamics is in overall agreements with the global reconstructions for the North
  Atlantic and Fennoscandia regions.
