Glaciation change in the northern part of the Middle Range on the Kamchatka Peninsula in the second half of the XX century

The paper examines changes in surface area of glaciers in the north of Middle Ridge (Kamchatka Peninsula) occurred in the 1950s to the present. For this purpose, we used ASTER satellite imageries (2002), data of the USSR Glacier Inventory and aerial photographs of 1950. Vector boundaries of glacier...

Description
Summary:The paper examines changes in surface area of glaciers in the north of Middle Ridge (Kamchatka Peninsula) occurred in the 1950s to the present. For this purpose, we used ASTER satellite imageries (2002), data of the USSR Glacier Inventory and aerial photographs of 1950. Vector boundaries of glacier maps were created by the decoding of ASTER images. The received estimates show glaciers decline in this area of Kamchatka. The glacier area of Middle Ridge, presented in the USSR Glacier Inventory, diminished by 16.6%. Reduced glacier area is subject to change major climatic factors. During this period the average summer air temperatures is increasing and the amount of solid precipitation reduced. По спутниковым снимкам ASTER, материалам Каталога ледников СССР и аэрофотоснимкам 1950 г. оценено изменение площадей ледников северной части Срединного хребта на Камчатке с 1950 по 2002 г. За это время площадь ледников здесь сократилась на 16,6%, а 36 ледников, представленных в Каталоге ледников СССР, на снимках ASTER не обнаружены. Более всего сократились ледники с ориентацией на юг и юго-восток. Сокращение ледников соответствует изменениям основных климатических факторов: в этот период средние летние температуры воздуха возрастали, а количество твёрдых осадков сокращалось.
