Glacial regime of the highest Tien Shan mountain, Pobeda-Khan Tengry massif
Abstract Major processes controlling the existence of a large sub-continental glacier system were identified on the basis of glaciological, meteorological and isotopic analyses using expeditionary and long-term data. Observations were made on the southern Inylchek glacier located in the Pobeda-Khan...
