Characterizing the glacier surge dynamics in Yarkand basin, Karakoram using remote sensing

The Karakoram region contains a large number of surge-type glaciers, but few surging glaciers have been investigated by surface displacement and DEM differencing. paper presents the surge dynamics one unnamed glacier in Yarkand basin, between 2000 2019 using satellite imagery (e.g., Landsat Sentinel 2). Also, multiple high-resolution DEMs HMA Cartosat 1) were used to estimate mass transfer from reservoir zone receiving zone. differencing exhibit maximum thickening lower was ~190 ± 31 m whereas thinning upper ?17 2018 2016. gained 256 143 × 106 m3 ice 2011. than 0.07 0.02 d?1 quiescent phase 2011 it reached ~5 0.3 active (autumn 2015). terminus retreated ?765 89 1978 2016 advanced +681 57 during 2016–2019. This analysis indicate that gradual increase about four years before onset surge, long (three years) slow termination corroborate partially thermally controlled Svalbard-type surge.
