Shrinkage of Satopanth and Bhagirath Kharak Glaciers, India, from 1936 to 2013
We have compiled and analysed available records and data on the shrinkage of Satopanth (SPG) and Bhagirath Kharak (BKG) Glaciers, Uttarakhand, India, during the period 1936–2013. We estimate the mean retreat rates of the snouts of SPG and BKG for this period at 9.7±0.8m a–1 and 7.0±0.6m a–1 respecti...
