“…Our estimates show a surface lowing of this ice cap of 0.26 ± 0.06 m a −1 over 1972–2015, which is consistent with the results of Li and others (2007). Based on Real Time Kinematic-Global Position System elevation measurements and DEMs generated from 1 : 50 000 topographical maps from 1972, Wang and others (2015) reported a thinning of 0.51 m a −1 over the ablation zone of the Yushugou No. 6 (43°05′ N, 94°19′ E) glacier during 1972–2011, which is broadly consistent with our estimate for the ablation area of the same glacier (0.41 ± 0.07 m a −1 over 1972–2015).…”

Despite a number of studies reporting glacier extent changes and their response to climate change over the eastern Tien Shan, glacier mass-balance changes over multiple decades are still not well reconstructed. Here, glacier mass budgets on the Karlik Range, easternmost Tien Shan during the time spans of 1972–2000 and 2000–2015 are quantified using digital elevation models reconstructed from topographic maps, SRTM X-band radar data and ASTER images. The results exhibit significant glacier mass loss in the Karlik Range for the two time spans, with a mean mass loss of −0.19 ± 0.08 m w.e. a−1 for the 1972–2000 period and −0.45 ± 0.17 m w.e. a−1 for the 2000–2015 period. The doubling of mass loss over the latter period suggests an acceleration of glacier mass loss in the early 21st century. The accelerated mass loss is associated with regional warming whereas the decline in annual precipitation is not significant.

“…We used 100 MHz frequency antennas, with a 4 m separation between the two antennas. The ice thickness is computed using the two-way travel time between GPR and glacier–bedrock interface by assuming a wave velocity through the glacier's ice of 0.169 m ns –1 (Wang and others, 2015). The thickness data were interpolated by the Ordinary Kriging method to produce a raster of glacier thickness with the same projection as the DEMs.…”

ABSTRACT. Global climate change is causing widespread glacier retreat, with many small glaciers disappearing from the world's mountain ranges. We obtained the annual mass balance of a small glacier (the Ningchan No.1 Glacier) located on the northeastern Tibetan Plateau, from the years 2010 to 2015 using glaciological and geodetic methods. We also measured the glacier's thickness in 2014 using ground-penetrating radar. Employing topographical maps and ZY-3 images, we obtained Digital Elevation Models for 1972 and 2014. Our results showed that the mean annual mass balance from 2010 to 2015 was ∼−0.9 ± 0.5 m w.e. The mean equilibrium line altitude was ∼4680 m in the period 2010-15, which exceeds the maximum elevation of the glacier. The glacier has lost area and mass across its elevation range. The mean ice thickness was 24.0 ± 2.5 m in 2014. From 1972 to 2014, the glacier's area shrank from 0.77 ± 0.05 to 0.39 ± 0.04 km 2 , and the ice volume decreased by (14.96 ± 0.97) × 10 6 m 3 , equivalent to (12.72 ± 0.82) × 10 6 t w.e. over the same period.

“…Also, continuously extensive shrinkage of glaciers in this region with an accelerated rate in recent decades has been reported (Khromova et al, 2003;Narama et al, 2010;Bolch et al, 2012;Sorg et al, 2012). Glacier meltwater caused by intensified glacier ablation plays an important role in sustaining human habitats and ecosystems within arid and semiarid regions (Hagg et al, 2007;Wang et al, 2014c).…”
