An estimate of the glacier ice volume in the Swiss Alps

Global and Planetary Change, 2009
Abstract Changes in glacier volume are important for questions linked to sea-level rise, water resource management, and tourism industry. With the ongoing climate warming, the retreat of mountain glaciers is a major concern. Predictions of glacier changes, necessarily need the present ice volume as initial condition, and for transient modelling, the ...

Monitoring glacier elevation and volume changes with digital photogrammetry and GIS at Gepatschferner glacier, Austria

International Journal of Remote Sensing, 2006
Digital elevation models of Gepatschferner in Northern Tyrol, Austria were obtained with digital photogrammetry from high altitude stereo photo pairs and by digitizing an analogue topographic glacier map, for 1990 and 1971, respectively. A difference map was calculated to identify regions of glacier elevation increases and decreases corresponding to ...

Quantification of glacier volume change using topographic and ASTER DEMs

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
Satellite imagery has been largely used to measure glacier surface evolution by detecting surface change between two images taken at different dates. But until now it seemed difficult to evaluate glacier volume changes from space. In this study, volume changes of three small glaciers in the Cordillera Blanca (northern Peru) between 1962 and 2001 are ...

Estimation of Glacier Volume and Volume Change by Scaling Methods

2011
While difficult to measure directly, glacier volume can be more easily approximated by measuring surface area and applying a power-law scaling relationship. The volume– area scaling relationship has been predicted and well established from field data, theory, and numerical modeling.

Estimation of paleo-extent and volume of glaciers in the Baspa basin, India

2023
Understanding water resources' long-term availability under varying climatic conditions is vital for water security and adaptation strategies. Due to increased temperature and changes in precipitation patterns, the Himalayan glaciers undergo rapid mass loss.

Volume Change of the Tasman Glacier Using Remote Sensing

2008
Mountain glaciers are expected to be the greatest contributor to sea level rise over the next century. Glaciers provide a good indicator of global climate and how to monitor their change is an increasingly important issue for climate science and for sea level rise forecasts.
