内容記述 | Out of 4530 glaciers covering ∼4770 km2 in the Upper Indus Basin, viz., Chenab, Zanaskar and Suru sub-basins, we selected topographically and morphologically homogeneous set of 98 glaciers; 56 debris-covered and 42 clean to assess the impact of debris-cover on glacier melting. Satellite data analysis from 2000 to 2017 showed that the debris-covered glaciers have melted slower (2.49 ± 0.05%; 0.15%a−1) than the clean glaciers (4.07 ± 0.03%; 0.24%a−1). The intra-basin analysis revealed that clean and debris-covered glaciers in the Chenab have melted 2.34 ± 0.17% and 1.1 ± 0.30% (0.14%a−1 and 0.06%a−1) and retreated 8.82 ± 2.67ma−1 and 5.7 ± 2.67ma−1 respectively. Similarly, clean and debris-covered glaciers in the Zanaskar have melted at similar rates of 4.58 ± 0.07% and 4.55 ± 0.21% (0.27%a−1 and 0.25%a−1) and retreated 10.0 ± 2.67ma−1 and 8.4 ± 2.67ma−1 respectively. Clean and debris-covered glaciers in the Suru have melted 5.56 ± 0.09% and 4.53 ± 0.14% (0.33%a−1 and 0.27%a−1) and retreated 9.6 ± 2.67ma−1 and 7.0 ± 2.67ma−1 respectively. Extensive debris-cover of ∼32.3% modulates glacier loss in the Chenab and sparse debris-cover of 11.4% and 6.4% in the Suru and Zanaskar enhances the melting of the debris-covered glaciers. Overall, debris-covered glaciers melted slower than the clean glaciers, with inter- and intra-basin variations, suggesting that debris-cover plays a complex but significant role in modulating glacier melting under climate change. | |||||
