Automated modelling of spatially-distributed glacier ice thickness and volume [PDF]

Computers and Geosciences, 2016
Ice thickness distribution and volume are both key parameters for glaciological and hydrological applications. This study presents VOLTA (Volume and Topography Automation), which is a Python script tool for ArcGISTM that requires just a digital elevation model (DEM) and glacier outline(s) to model distributed ice thickness, volume and bed topography ...

Improving estimation of glacier volume change: a GLIMS case study of Bering Glacier System, Alaska [PDF]

The Cryosphere, 2007
International audienceThe Global Land Ice Measurements from Space (GLIMS) project has developed tools and methods that can be employed by analysts to create accurate glacier outlines and resultant measures of glacier extent.

Glacier thickness and ice volume of the Northern Andes [PDF]

Scientific Data, 2022
AbstractTropical 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 their thicknesses and volumes, which is currently lacking in the Northern Andes.

A review of volume‐area scaling of glaciers

Reviews of Geophysics, 2015
AbstractVolume‐area power law scaling, one of a set of analytical scaling techniques based on principals of dimensional analysis, has become an increasingly important and widely used method for estimating the future response of the world's glaciers and ice caps to environmental change.

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

The Cryosphere, 2013
Abstract. 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. a level achieved only within ideal conditions) for its accuracy.

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.

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

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 ...

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 ...

Thinning of the Monte Perdido Glacier in the Spanish Pyrenees since 1981 [PDF]

, 2016
Producción CientíficaThis paper analyzes the evolution of the Monte Perdido Glacier, the third largest glacier in the Pyrenees, from 1981 to the present. We assessed the evolution of the glacier's surface area by analysis of aerial photographs from 1981,
