“…The current Siberian highland glacial record has been generated by palynological records, depositional lithologies, and glacial geomorphological reconstruction ( Fig. 9; Arkhipov et al 1986b;Bowen et al 1986;Velitchko et al 1989) and indicates that between 0 and 200 kyr B.P., the Siberian highland has undergone three glaciations, three interstadial events, and is currently in an interglacial, the Holocene (Fig. 9).…”

“…Glacial activity in the Baikal region has been limited to mountainous regions surrounding the lake (Back et al 1998(Back et al , 1999, and continental ice sheets have never scoured the region (Serebryanny 1984;Velitchko et al 1989). Consequently, sediments have accumulated across large expanses of Lake Baikal's basins (Pampoura et al 1993) since the Miocene to depths greater than 7.5 km (Hutchinson et al 1993).…”

Siliceous microfossil succession was analyzed in a 200,000‐yr sediment sequence recovered from the Buguldeika Saddle in Lake Baikal, Russia. Siliceous microfossil abundance varied among core depths from no preserved microfossils during inferred colder climate conditions to recent interglacial sediments containing over 300 × 106 microfossils per g dry sediment. Depth‐age microfossil assemblage zones (CA‐I to CA‐IV) identified using correspondence analysis had high correspondence to stages in the marine d18O isotope record and could be partially aligned with Late Pleistocene glacial‐interglacial cycling models from the mid‐Siberian Highland. These observations suggest that Lake Baikal phytoplankton communities have responded to climatic changes driven by insolation parameters and global ice volumes on temporal scales similar to tropical and polar oceans. Microfossil zone CA‐I (0–11.4 kyr B.P.) corresponded to the Holocene interglacial or d18O stage 1 (0–11.4 kyr B.P.), a period of higher production in Lake Baikal during a climatic optimum. Microfossil zone CA‐II (12.3–18.7 kyr B.P.) corresponded to the Sartan glaciation and d18O stage 2 (12–24 kyr B.P.). Zone CA‐III (21.3–73.2 kyr B.P.) comprised d18O stages 3 and 4. However, within zone CA‐III, subzones CA‐IIIa and IIIb (21.3–56.8 kyr B.P.) grouped were well aligned with d18O stage 3 and contained sediments deposited during the inferred Karginskiy interstade. Microfossil zone CA‐IVa (77.4–129.2 kyr B.P.) and CA‐IVb (130.3–172.5 kyr B.P.) included d18O stages 5 and 6, respectively, with sediments that were most likely deposited during the Taz glaciation and the Kazantsevo interstade. Climate‐induced changes are reflected in production differences and in community composition specificity within microfossil zones or climate stages. This suggests that climate change drives major historical successional patterns in Lake Baikal's primary producer community; changes in primary producers must have further impacted the system's entire biota.

A biogeographical analysis of the North Pacific temperate waters is made on the basis of the distribution of 88 species of Mysidacea (Crustacea) and 111 species of Anomura (Crustacea: Decapoda: Reptantia) inhabiting depths from 0 to 1000-12000 m. At depths from 0 to 180-200 m and from 180-200 to 1000-1200 m, division by mysid fauna is made separately; division according to anomurans is unified. Original schemes of faunistic zonation of the North Pacific are given. The influence of abiotic factors, primarily temperature, on the formation of distribution ranges of Pacific boreal species is examined.

“…1). However, whether the last glacial maximum on Taymyr really dates from the Late Weichselian around 18 000 years BP, or from an earlier part of the last glacial cycle is not at all clear (Velichko et al 1989). An Early Weichselian age would be more in line with recent conclusions for western Siberia (Astakhov 1992(Astakhov , 1997(Astakhov , 1998, and with a palaeoclimatic scenario proposing maximum glaciations in the east at the beginning of glacial cooling, when precipitation is still available, later gradually shifting towards maximum glaciation in the west, closer to the Atlantic precipitation source.…”

H. 1999 (March): Weichselian geology and palaeoenvironmental history of the central Taymyr Peninsula, Siberia, indicating no glaciation during the last global glacial maximum. Boreas, Vol. 28, The Taymyr Peninsula constitutes the eastern delimitation of a possible Kara Sea basin ice sheet. The existence of such an ice sheet during the last global glacial maximum (LGM), i.e. during the Late Weichselian/ Upper Zyryansk, is favoured by some Russian scientists. However, a growing number of studies point towards a more minimalistic view concerning the areal extent of Late Weichselian/Upper Zyryansk Siberian glaciation. Investigations carried out by us along the central Byrranga Mountains and in the Taymyr Lake basin south thereof, reject the possibility of a Late Weichselian/Upper Zyryansk glaciation of this area. Our conclusion is based on the following: Dating of a continuous lacustrine sediment sequence at Cape Sabler on the Taymyr Lake shows that it spans at least the period 39-17 ka BP. Even younger ages have been reported, suggesting that this lacustrine environment prevailed until shortly before the Holocene. The distribution of these sediments indicates the existence of a paleo-Taymyr lake reaching c. 60 m above present sea level. A reconnaissance of the central part of the Byrranga Mountains gave no evidence of any more recent glacial coverage. The only evidence of glaciation -an indirect one -is deltaic sequences around 100-120 m a.s.l., suggesting glacio-isostatic depression and a large input of glacial meltwater from the north. However, 14 C and ESR datings of these marine sediments suggest that they are of Early Weichselian/Lower Zyryansk or older age. As they are not covered by till and show no glaciotectonic disturbances, they support our opinion that there was no Late Weichselian/Lower Zyryansk glaciation in this area. We thus suggest that the Taymyr Peninsula was most probably glaciated during the early part of the last glacial cycle (when there was only small-to mediumscale glaciation in Scandinavia), but not glaciated during the later part of that cycle (which had the maximum ice-sheet coverage over north-western Europe). This fits a climatic scenario suggesting that the Taymyr area, like most of Siberia, would come into precipitation shadow during times with large-scale ice-sheet coverage of Scandinavia and the rest of north-western Europe.
