“…During the period from 1962 to 1979, two lateral tongues along the foot of the spurs melted splitting into individual perennial snow patches in some places, which reduced the glacier significantly. From 1979 to 2007, the glacier decreased by 45 m in length, and was reducing in thickness by an average of 20 m (Kovalenko 2008). And from 2007 to 2009, its length reduced sharply by 175 m due to melting.…”

“…The first works on aerospace information interpretation and large-scale mapping at the Kodar were conducted in 1979 (Plastinin and Plyusnin 1979;Plyusnin 1992;Plastinin 1998). And since 2007, a detailed study of the Kodar glaciers has been resumed (Kovalenko 2008).…”

It is presented the results of studying of small glaciers located in the Eastern Siberia along transect the Kodar mountains -Baikalskiy and Barguzinskiy ridgesthe Eastern Sayan mountains. Some glaciers from this transect have not been described before. The inventorying of these glaciers is based on high-resolution satellite images and fieldworks. The most numbers of glaciers are located in the Kodar mountains and few are in the Baikalskiy and the Barguzinskiy ridges. Most likely, these glaciers remained mainly due to coldest winters and geomorphologic features. The main parameters of a glacier's data (the dynamics, the current state, cartographic representation, remote sensing data and others) are selected by analogy of the international glaciological database.

“…Modern glaciers in the high mountain ranges in Mongolia play a vital role in water resources in Central Asia, and also in regional ecological, social and economic development. Modern glaciers in the high mountain ranges provide over 70% of fresh water resources in Mongolia [5] and small mountain glaciers in high latitudes and high altitudes are very sensitive to climate change [6]. Thus climate change can modulate water resources through altering glacier mass balances [7], and this has a large impact on regional development.…”

“…In the Khuvsgul Mountain Range, Tsegmid [1] estimated the extents of past glaciations based on glacial deposits, and absolute age dating suggests that maximum glacier advances were approximately synchronous across northern Mongolia [27]. Late Pleistocene glaciers around the Darkhad basin (Figure 2 at 2100 -2200 m a.s.l and an ice thickness of 300 -400 m [6]. There was no glaciation during the Atlantic period (7000 -7300 years ago) and modern glaciers have been present for the last 4000 -5000 years [6].…”

Water trapped in glaciers and in lakes impounded by landforms created by glaciers (glacial lakes) are an important component of the hydrology and water resources in high mountain areas of Central Asia. Changes in modern glaciers and glacial lakes are an important component of the hydrology of watersheds in the Mongolian Altai and Khuvsgul Mountain Ranges, western and northern Mongolia, respectively. Here we focus on Mt. Ikh Turgen and Mt. Munkh Saridag, isolated mountains of the Mongolian Altai and Khuvsgul Mountain Ranges, respectively. We use remote sensing to track changes in modern glaciers over time with mapping at scales of 1:200,000 for Mt. Ikh Turgen and 1:90,000 for Mt. Munkh Saridag based on imagery from Google Earth, 30 m resolution Aster Digital Elevation Model (DEM) and 30 m resolution Landsat 5 TM. Mt. Ikh Turgen lost 45.6% of its total glacier area between 1970 (41.4 km 2) and 2011 (18.9 km 2) and the Equilibrium Line Altitude (ELA) of the glaciers increased in elevation by 98 m and 144 m on north and south aspects, respectively. Mt. Munkh Saridag lost 57.3% of its total glacier area between 1970 (901 m 2) and 2007 (381 m 2) and the local ELA rose by 47 m and 80 m on north and south aspects, respectively. These mountains are located at similar latitudes, and so the greater percentage loss of glacier area in Mt. Munkh Saridag and faster changes in ELAs in Mt. Ikh Turgen may reflect variations in elevation and aspect, duration of solar radiation, and vulnerability to solar radiation, as well as variations in glacier scale. This study demonstrates the importance of spatial analyses of modern glaciers in understanding the context of hydrological changes within which any sustainable water resource management plan must be situated.
