“…Lichenometry has been used extensively to date Holocene moraines in Kamchatka (Solomina et al, 1995;Savoskul and Zech, 1997;Solomina, 1999;Golub, 2002;Solomina and Calkin, 2003;Manevich, 2011), but conflicting growth curves for both Rhizocarpon geographicum and Rhizocarpon alpicola currently exist. This creates problems with deriving accurate and consistent lichenometric dates, and is discussed in detail by Solomina and Calkin (2003).…”

“…In the Topolovaya Valley, Savoskul and Zech (1997) find evidence to suggest two phases of ice advance and moraine formation during the Late Holocene. A minimum age constraint for these moraines (M4, M8, LM8 in table 2) is provided by the Ksudach 1 (KS1) tephra (c.1.8 ka), which drapes their surfaces.…”

“…Some evidence, which appears to relate to this period, is found within the Topolovaya Valley (~53.153°N, 158.014°E) (see site location in figure 1), where moraines are located 2.5-3.5 km inside inferred gLGM ice limits . Though direct age-estimates for these moraines are lacking, Savoskul and Zech (1997) consider them to be of Late Glacial age because of a down-valley moraine which is assigned to the gLGM on the basis of 'soil properties' and an overlying Kuril Lake Caldera tephra (KO) dated to c. 8.5 ka (table 1). A comparable group of moraines, considered to have been deposited during the Late Glacial , is found within the headwaters of Sredniya Avacha (~53.891°N, 158.187°E) (see site location in figure 1).…”

“…First, in the Topolovaya Valley, Savoskul and Zech (1997) identify moraine sequences (see moraines M2, M3, M6 and M7 in table 2) reflecting the former presence of glaciers ~1.5-1.8 km long (figure 4), which are assigned to the Early to Mid-Holocene on the basis of the KO tephra (c. 8.5 ka) (table 1), which drapes their surfaces . finds similar evidence in the headwaters of Sredniya Avacha.…”

“…Solomina et al, 1995Solomina et al, , 2007Yamaguchi et al, 2008), and few investigations have focused upon the Holocene as a whole Yamagata et al, 2000Yamagata et al, , 2002, despite Kamchatka offering one of the bestresolved Holocene tephra sequences anywhere in the world Ponomareva et al, 2007Ponomareva et al, , 2013. With this in mind, the purpose of this paper is to summarise current understanding of Holocene glacier fluctuations upon the Kamchatka Peninsula (Solomina et al, 1995(Solomina et al, , 2007Savoskul and Zech, 1997;Yamagata et al, 2002;Solomina et al, 2007;Yamaguchi et al, 2008), and to place this information in a wider palaeoglacial and palaeoclimatic context. In order to achieve this aim, an overview of ice extent upon the peninsula during earlier (pre-Holocene) phases of glaciation is also outlined.…”

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.

Glaciers and climate in Pacific Far NE Russia during the Last Glacial Maximum

A combined geomorphological-physical model approach is used to generate three-dimensional reconstructions of glaciers in Pacific Far NE Russia during the global Last glacial Maximum (gLGM). The horizontal dimensions of these ice masses are delineated by moraines, their surface elevations are estimated using an iterative flowline model and temporal constraints upon their margins are derived from published age estimates. The equilibrium line altitudes (ELAs) of these ice masses are estimated, and gLGM climate is reconstructed using a simple degree-day melt model. The results indicate that, during the gLGM, ice masses occupying the Pekulney, Kankaren and Sredinny mountains of Pacific Far NE Russia were of valley glacier and ice field type. These glaciers were between 7 and 80 km in length, and were considerably less extensive than during pre-LGM phases of advance. gLGM ice masses in these regions had ELAs of between 575 AE 22 m and 1035 AE 41 m (above sea level) -corresponding to an ELA depression of 350-740 m, relative to present. Data indicate that, in the Pekulney Mountains, this ELA depression occurred because of a 6.48C reduction in mean July temperature, and 200 mm a À1 reduction in precipitation, relative to present. Thus reconstructions support a restricted view of gLGM glaciation in Pacific Far NE Russia and indicate that the region's aridity precluded the development of large continental ice sheets.
