INVESTIGATION OF MOUNTAIN GLACIER STORAGE AND ITS CHANGES DURING 2000–2016 IN THE WESTERN TIBETAN PLATEAU USING COMBINED GROUND AND SATELLITE OBSERVATIONS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
The Upper Indus River Basin (UIB) has developed the largest midlatitude mountain glaciers worldwide. Ice thickness and volume distribution are important prerequisites for glaciological and hydrological investigations. In this paper, we presented detailed

Rapid demise and committed loss of Bowman Glacier, northern Ellesmere Island, Arctic Canada

Journal of Glaciology, 2023
Using historical and recent aerial photography and structure from motion (SfM) multiview stereo (MVS) techniques, we reconstruct the 1959 and 2018 ice surface topography and determine the geodetic mass balance of Bowman Glacier, a small mountain glacier ...

Volume, evolution, and sedimentation of future glacier lakes in Switzerland over the 21st century

Earth Surface Dynamics, 2022
. Ongoing climate change and associated glacier retreat is causing rapid environmental change, including shifts in high-alpine landscapes. Glacier lakes, which can form in topographical depressions left behind by glacier retreat, are prominent features ...

Estimation of glacier ice storage in western China constrained by field ground-penetrating Radar surveys

Advances in Climate Change Research, 2022
Recent decades have witnessed the accelerated retreat of alpine glaciers, which likely portends a decline in the glacial ice melt on which large downstream populations rely for freshwater. Thus, estimating water storage in alpine glaciers is critical for

Probabilistic estimation of glacier volume and glacier bed topography: the Andean glacier Huayna West [PDF]

, 2013
Abstract. Glacier retreat will increase sea level and decrease fresh water availability. Glacier retreat will also induce morphologic and hydrologic changes due to the formation of glacial lakes. Hence, it is important not only to estimate glacier volume, but also to understand the spatial distribution of ice thickness. There are several approaches for

Calibration of a frontal ablation parameterisation applied to Greenland's peripheral calving glaciers

Journal of Glaciology, 2021
We calibrate the calving parameterisation implemented in the Open Global Glacier Model via two methods (velocity constraint and surface mass balance (SMB) constraint) and assess the impact of accounting for frontal ablation on the ice volume estimate of ...

Influence of glacier inventories on ice thickness estimates and future glacier change projections in the Tian Shan range, Central Asia

Journal of Glaciology, 2023
The Tian Shan mountain range, known as the water towers of Central Asia, plays a key role in local water supply, yet large uncertainties remain about the amount of water that is stored in its glaciers.

Effect of topography on subglacial discharge and submarine melting during tidewater glacier retreat. [PDF]

, 2017
-We explored secular variations in subglacial discharge and submarine melting with an idealized model -Subglacial discharge increases as tidewater glaciers retreat along retrograde beds -Submarine melting depends on subglacial discharge and ...

Global glacier volume projections under high-end climate change scenarios [PDF]

The Cryosphere, 2018
Abstract. The Paris agreement aims to hold global warming to well below 2 °C and to pursue efforts to limit it to 1.5 °C relative to the pre-industrial period. Recent estimates based on population growth and intended carbon emissions from participant countries, suggest global warming may exceed this ambitious target.

Changes in Imja Tsho in the Mount Everest Region of Nepal [PDF]

, 2014
Imja Tsho, located in the Sagarmatha ( Everest) National Park of Nepal, is one of the most studied and rapidly growing lakes in the Himalayan range. Compared with previous studies, the results of our sonar bathymetric survey conducted in September of ...
