Abstract. Glaciers in the Pamir Mountains are generally acknowledged to be
in a stable state and show the least glacial retreat in high-mountain Asia;
however, they are also some of the most dynamic glaciers in the region and
their behaviour has been spatially variable in recent decades. Few data exist
for these glaciers, in particular relating to how they are responding to
recent climatic changes. Here, we utilize Landsat 7 (ETM+), Landsat 8
(OLI), ASTER, and Google Earth optical images acquired between 1999 and 2016
to characterize the dynamics of the glaciers in the Kingata Mountains,
located in the eastern Pamir Mountains. We quantify the velocity, areal, and frontal
changes of these glaciers, which provide us with valuable data on their
recent dynamic evolution and an indication of how they may evolve in future
years. We highlight 28 glaciers among which 17 have changed markedly over the
study period. We identify four advancing glaciers and 13 surge-type glaciers.
The dynamic evolution of the glacier surges shows some similarity with those
of the nearby Karakoram, suggesting that both hydrological and thermal
controls are important for surge initiation and recession. Topography seems
to be a dominant control on non-surge glacier behaviour in the Kingata
Mountains, with the north side of the divide characterized by steep,
avalanche-fed basins and glacier tongues now approaching recession in
contrast to those on the south side of the divide that capture the majority
of precipitation and have much broader plateau-like accumulation zones. This
study is the first synthesis of glacial motion across this region and
provides a baseline with which to compare future changes.
