Glaciological researches in the Sector of geography started in 1939 under the leadership of N.N. Palgov. Glaciological researches especially intensively developed in the period of the International Geophysical Year (1957-59), International Hydrological Decade (1965-74) and International Hydrological Program, when together with the other geographical centers of the former USSR, there were conducted glacio-hydro-climatic researches in all mountain-glacier regions of Kazakhstan. Beginning from 1963, the compilation of the Catalogue of Glaciers of the USSR and activity of the International program «Fluctuation of glaciers mode» had started. In 1965–1974, scientists of the Sector of Geography of the Academy of Sciences of the KazSSR participated in the program of the International Hydrological Decade. In 1980, there were made about 80 glaciological maps for the «Atlas of snow-ice resources of the world». Glaciological researches were made in all mountain regions of Kazakhstan in different time. The most studied regions are Zhetysu (Dzhungarskiy) and Ile (Zailiyskiy) Alatau. Etalon glaciers of the World Glacier Monitoring Service – Shumskiy and Tuyuksu, are located in those regions.
Glacier Central Tuiyksu
Main directions of researches:
- Monitoring of the development of the components of cryosphere in the zone of runoff formation (snow cover, glaciers, underground ices);
- Creation of new glaciers inventories of the control basins in a volume required for reliable determination of the area of glaciation and glacier resources;
- Study of climatic conditions of glacier evolution, ablation and runoff in the second half of the XX-th and beginning of the XXI-st centuries;
- Calculation and compilation of the map of distribution of altitude of climatic snow border in the territory of transboundary basins;
- Calculation and compilation of map of distribution of annual accumulation of solid precipitation at the altitude of snow border;
- Assessment of modern and prognostic changes of glacial systems of transboundary basins;
Assessment of climate caused changes of temperature mode of permafrost grounds.

Scientific expeditions and field works
3 high-mountain research stations with the complex of year-round monitoring on the Northern Tien-Shan: glaciological «Tuiyksu glacier», hydrophysical «Big Almaty Lake» and geocryological «Zhosaly-Kezen»
Experimental base of department consist of 3 -mountain research stations with the complex of year-round monitoring on the Northern Tien-Shan: glaciological «Tuiyksu glacier» in the basin of Kishi Almaty river at the altitude of 3500 m, hydrophysical «Big Almaty Lake» and geocryological «Zhosaly-Kezen» in the basin of Ulken Almaty river at the altitudes of 2500 and 3400 m correspondingly. Research station «Tuiyksu glacier», which is the only one in the territory of CIS where remained year-round monitoring of components of mass balance of Tuiyksu glacier and the data is yearly provided to World Glaciers Monitoring Service. At the high-mountain station «Zhosaly-Kezen» is conducted monitoring for the temperature mode of multi-year frozen grounds and impact of climatic changes to their condition is studied.
Determination of maximal snow-water equivalent in zone of runoff formation
Drilling and installation of accumulation-ablation sticks on the glaciers Tuiyksu and Manshuk Mametova
Drilling works and sticks installation on the glaciers. Replacement of wooden sticks on the glacier after melting. There are 115 sticks installed on Tuiyksu glacier and 10 on Manshuk Mametova glacier.
Geodetic works in glacial-nival zone of Ile and Zhetysu Alatau
Bathymetric works on high-mountain lakes aimed to determine main morphometric characteristics
Aero-visual survey of high-mountain lakes with potential risk of outburst
Realized programs of fundamental and applied researches allowed receiving following main results:
- On the basis of comparative analysis of data of catalogues of glaciers made by materials of aerosurveying in 1956, 1975, 1979 and 1990 and satellite photographs of the later periods, there were studied the dynamic of glaciation of the mountains of the region for the period from 1955 to 2011 and made prognosis of probable changes of ice resources for the period till 2050;
- It is determined that temps of degradation of glaciation during the last half of century were not constant. They considerably reduced after maximum in 70-ies and there are reasons to consider that the process of their reduction is going on now;
- It is determined that in spite of considerable (more than 30% for 40 years) reduction of ice in mountains, norms of runoff during the last decades did not change significantly. During that period, the norms of atmospheric precipitation and maximal snow accumulation remain stable and that gives reason to assume that there exist certain compensatory mechanism;
- It is proved that loss of runoff connected with degradation of glaciation is compensated by melted water of underground ices, storages of which are comparable with storages of surface glaciation. According to the same tendencies of climate change, glaciation, sums of precipitation and maximal snow accumulation, it gives us reason to hope that water resources in Central Asia in the next decades would remain relatively sustainable.

Prospects of development
Indicator of authority of glaciologists of the Institute is the Central Asian Regional Glaciological Center under auspices of the UNESCO created by the Institute of Geography on the basis of the Department of Glaciology in accordance Law of Republic of Kazakhstan about ratification of Agreement between the UNESCO and the Government of the Republic of Kazakhstan signed on 1-th of March 2017 in Astana by President of the Republic of Kazakhstan Nazarbaev N.A.. Such Center is created for the first time in the World.
