Mass Balance Factsheet for the Maliy Aktru glacier, Altay
The valley-type glacier is located on the northern slope of the North Chuyskiy Range of the Russian Altai Mountains. It extends from 3714 m to 2246 m a.s.l., has a surface area of 2.72 km2 and is exposed to the east and north. It has an average thickness of 90 m (max. 234 m) and its total volume is estimated to be 0.25 km3. Mean annual air temperature at the equilibrium line of the glacier (around 3160 m a.s.l. for balanced conditions) is -9 to -10°C.
The glacier is polythermal and surrounded by continuous to discontinuous permafrost. Average annual precipitation, as measured at 2130 m a.s.l., is about 540 mm. Mass balances of three glaciers within the same basin are being determined.
