An estimate of global glacier volume [PDF]
The 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

Accelerating glacier volume loss on Juneau Icefield driven by hypsometry and melt-accelerating feedbacks. [PDF]
Nat CommunGlobally, glaciers and icefields contribute significantly to sea level rise. Here we show that ice loss from Juneau Icefield, a plateau icefield in Alaska, accelerated after 2005 AD.

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

Glacier thickness and ice volume of the Northern Andes [PDF]
Scientific Data, 2022 Tropical glacier melt provides valuable water to surrounding communities, but climate change is projected to cause the demise of many of these glaciers within the coming century. Understanding the future of tropical glaciers requires a detailed record of

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

Glacier volume‐area relation for high‐order mechanics and transient glacier states [PDF]
Geophysical Research Letters, 2012 Glacier volume is known for less than 0.1% of the world's glaciers, but this information is needed to quantify the impacts of glacier changes on global sea level and regional water resources. Observations indicate a power‐law relation between glacier area and volume, with an exponentγ≈ 1.36.

What is the global glacier ice volume outside the ice sheets?
Journal of Glaciology, 2023 A recent study (Millan and others, 2022a, Nature Geoscience 15(2), 124–129) claims that ice volume contained in all glaciers outside the ice sheets and its potential contribution to sea level is 20% less than previously estimated.

Glacier volume estimation as an ill-posed inversion [PDF]
Journal of Glaciology, 2014 AbstractEstimating a glacier’s volume by inferring properties at depth (e.g. bed topography or basal slip) from properties observed at the surface (e.g. area and slope) creates a calculation instability that grows exponentially with the size of the glacier.

Modelling glacier-bed overdeepenings and possible future lakes for the glaciers in the Himalaya—Karakoram region [PDF]
Annals of Glaciology, 2016 Surface digital elevation models (DEMs) and slope-related estimates of glacier thickness enable modelling of glacier-bed topographies over large ice-covered areas.

The physical basis of glacier volume-area scaling [PDF]
Journal of Geophysical Research: Solid Earth, 1997 Ice volumes are known for only a few of the roughly 160,000 glaciers worldwide but are important components of many climate and sea level studies which require water flux estimates. A scaling analysis of the mass and momentum conservation equations shows that glacier volumes can be related by a power law to more easily observed glacier surface areas ...
