 “As per study conducted by the Wadia Institute of Himalayan Geology on the mass balance and other aspects in the Pensilungpa Glaciers in Suru basin, Indus river catchment, the glaciers in the basin are retreating. For long term measurement of mass balance and other parameters, the Space Applications Centre (SAC) of Indian Space Research Organisation has carried out two projects viz., “Snow and Glacier Studies” and “Monitoring Snow and Glaciers of Himalayan Region (Phase-II)”. One of the components of these projects relates to estimation of glacier mass balance using multi-date satellite data. Under these two projects glacier mass balance was estimated based on analysis of multi-date satellite data using Accumulation Area Ratio (AAR) approach. Glacier specific mass balance has been estimated for glaciers in 9 sub-basins viz., Nubra, Zanskar, Warwan, Bhut, Chandra, Bhaga, Miyar, Parbati, Baspa of the Indus basin. Observations indicate overall positive mass balance at sub-basin level for Indus basin. Results of the study are given in the table below:
