High-latitude alpine glaciers are sensitive climate indicators and the most greatly they respond on the

The main topics of this report are the revision, generalization of collected data, making detailed diagrammatic curves of glacier’s size fluctuations for the modeling task solution. Data from the 1932, 1947, 1953, 1960, 1973 1982–2008 are important for the detailed reconstruction of fluctuations line of glacier’s square area, length and the surface altitude and their connection with climate.

For the glacier’s fluctuations estimation numerical models of the surface, based on the topoplans were made. On this numerical models the contours of glaciers for different years were overlaid. Size, square area and surface altitude fluctuations were calculated. The material of moraine research was generalized too. The photographs of glaciers from different years are collecting for the new “Catalogue of repeated images”, which will represent climate and nature environment changing.
