An estimate of global glacier volume [PDF]

open access: yesThe Cryosphere, 2013
I assess the feasibility of using multivariate scaling relationships to estimate glacier volume from glacier inventory data. Scaling laws are calibrated against volume observations optimized for the specific purpose of estimating total global glacier ice

An upper-bound estimate for the accuracy of glacier volume–area scaling [PDF]

open access: yesThe Cryosphere, 2013
Volume–area scaling is the most popular method for estimating the ice volume of large glacier samples. Here, a series of resampling experiments based on different sets of synthetic data is presented in order to derive an upper-bound estimate (i.e.

Volume-area scaling for debris-covered glaciers [PDF]

open access: yesJournal of Glaciology, 2020
A volume-area scaling relation is commonly used to estimate glacier volume or its future changes on a global scale. The presence of an insulating supraglacial debris cover alters the mass-balance profile of a glacier, potentially modifying the scaling ...

Global glacier-free topography reveals a large potential for future lakes in presently ice-covered terrain [PDF]

open access: yesNature Communications
Glacier retreat transforms landscapes in polar and mountainous regions. Yet, the topography of the emerging terrain remains poorly known. Here, we present a physically consistent, global map of the ice-covered topography beneath all glaciers on Earth ...

Increasing rate of 21st century volume loss of the Patagonian Icefields measured from proglacial river discharge

open access: yesJournal of Glaciology, 2023
The Northern and Southern Patagonian Icefields are rapidly losing volume, with current volume loss rates greater than 20 km3 a−1. However, details of the spatial and temporal distribution of their volume loss remain uncertain.

A Bayesian ice thickness estimation model for large-scale applications

open access: yesJournal of Glaciology, 2020
Accurate estimations of ice thickness and volume are indispensable for ice flow modelling, hydrological forecasts and sea-level rise projections. We present a new ice thickness estimation model based on a mass-conserving forward model and a Bayesian ...

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

open access: yesThe 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

open access: yesJournal 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 ...

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

open access: yesAdvances 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

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

open access: yesJournal 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 ...
