“…mountains only small glaciers with a maximum length of up to 3.5 km are preserved. In the Suntar Chajata, glaciers cover an area of more than 200 km² (Krenke and Chernova, 1980;Koreisha, 1991;Murzin, 2003;Ananicheva and Krenke, 2005;Ananicheva et al, 2008).…”

Geomorphological mapping revealed five terminal moraines in the central Verkhoyansk Mountains. The youngest terminal moraine (I) was formed at least 50 ka ago according to new IRSL (infrared optically stimulated luminescence) dates. Older terminal moraines in the western foreland of the mountains are much more extensive in size. Although the smallest of these older moraines, moraine II, has not been dated, moraine III is 80 to 90 ka, moraine IV is 100 to 120 ka, and the outermost moraine V was deposited around 135 ka. This glaciation history is comparable to that of the Barents and Kara ice sheet and partly to that of the Polar Ural Mountains regarding the timing of the glaciations. However, no glaciation occurred during the global last glacial maximum (MIS 2). Based on cirque orientation and different glacier extent on the eastern and western flanks of the Verkhoyansk Mountains, local glaciations are mainly controlled by moisture transport from the west across the Eurasian continent. Thus glaciations in the Verkhoyansk Mountains not only express local climate changes but also are strongly influenced by the extent of the Eurasian ice sheets.

A summary of the extent and chronology of Quaternary glaciations in NE Russia is presented in this paper. The complex timing and style of glaciations include asynchronous development of alpine glaciers in the western and eastern part of the area. While in the eastern part of NE Russia well-preserved moraines have been dated to the global Last Glacial Maximum (18-24 ka), in the westernmost part of the area no glacial advance took place at this time. In general, glacial advances were more extensive earlier rather than later, in the last glacial cycle. Although only a handful of studies with reliable absolute ages in the vast area of NE Russia exist, it is clear that the number of advances throughout the region varies. Variable glacial response to global climate patterns is attributable to contrasting sources of precipitation. An Atlantic moisture source dominates in the western part of NE Russia, while a Pacific source influences the eastern part of the region. The glacial advances in the interior of NE Russia are largely unexplored and further research is needed in order to understand Quaternary climate change in the region.

“…In northeast Siberia where glaciers are cold-based, superimposed ice prevails; therefore a significant fraction of meltwater refreezes and then melts again at the surface. In this case it is possible to use a regional variant of the "global" formula relating A to summer temperature (T sum ), presented by Krenke and Khodakov (1966;in Krenke, 1982), which was proposed by Koreisha (1991) and confirmed in calculations for Glacier 31 for reconstruction of the Suntar-Khayata glaciation during the Holocene optimum (Ananicheva and Davidovich, 2002):…”

“…To complement the sparse meteorological-station data for high elevations (above 1000 m), we used the accumulation at the mean ELA for the each glacier group (10-15 glaciers), which was calculated from the Glacier Inventory 1 data or obtained from their maps (Krenke, 1982;Ananicheva and Krenke, 2005). These maps were widely used in the Atlas of Snow and Ice Resources, published in Moscow (Kotlyakov, 1997).…”

We studied contrasting glacier systems in continental (Orulgan, Suntar-Khayata and Chersky ranges located in the Pole of Cold of Eurasia area at the contact of Atlantic and Pacific influences and maritime (Kamchatka Peninsula) – under Pacific influence. Our purpose is to present a simple projection method to asses the main parameters of these glacier regions under climate change. To achieve this, constructed vertical profiles of mass balance (accumulation and ablation) based both on meteorological data for 1950–90s and ECHAM4 for 2040–2069 are used, the latter – as a climatic scenario. Also for selected key glacier systems other models were applied for comparison. The observations and scenarios were used to define the recent and future equilibrium line altitude (ELA) and glacier termini elevation for each glacier system. <br><br> The altitudinal distributions of ice areas were determined for present and future, they were used for prediction of the elevation spreading of glaciers in the system taking into account the correlation between the ELA and glacier-termini level change. We tested two hypotheses of ice distribution versus altitude in mountain (valley) glaciers – linear and non-linear. The results are estimates of the possible changes of the areas and morphological structure of Northeastern Asia glacier systems and their mass balance characteristics for 2049–60. Finally, we compare characteristics of the stability of continental and maritime glacier systems under global warming
