Divergent temporal glacier responses in the Chandra-Bhaga and Suru-Zanskar Basins of the Indian Western Himalaya

Assessment of temporal fluctuation of glaciers due to climate change is essential for several aspects of glaciology research, including future prediction and various modelling. Therefore, the present study aims to calculate the temporal changes in glacier areas and retreats in the Suru-Zanskar Basin (SZB) and Chandra-Bhaga Basin (CBB). At first, 45 sample glaciers were manually digitized for 2000, 2007, 2016, and 2022 for the SZB. Likewise, 51 sample glaciers were taken for the CBB. After that, the Friedman and Dunn tests were conducted to compare the area changes and retreat rates in the SZB and CBB from sample glaciers. The Mann-Kendell test and Sen slope indicate the temperature was increased at a rate of 0.0091 ± 0.00014°Cyr-1 between 1901 and 2021 in the CBB. The total sample glacier area has changed from 608.95 km2 to 584.54 km2 between 2000 and 22 in the CBB. The temporal assessment shows glacier area changes, and retreat shows a heterogeneous trend. The average area changes lie between -0.187 to -0.285, -0.303 to -0.483, -0.165 to -0.313, and -0.237 to -0.324 %yr-1 in 2000-09, 2009-16, 2016-22, and 2000-22 respectively. Also, the average retreat lies between 8.03 to 13.2 myr-1, 12 to 18.5 myr-1, 16.7 myr-1 to 31.3 myr-1 and 12.7 to 18.8 myr-1 in 2000-07, 2007-16, 2016-22 and 2000-22 respectively. On the other hand, the sample glacier area changed from 913.77 km2 to 894.69 km2 through the study period in the SZB. The temporal assessment shows a uniform areal shrinkage and retreat of glaciers in all timeframes in the SZB. The Guha et al. (2023) dataset is accessible at https://doi.org/10.5281/zenodo.8242507
