Glacier Mass Balance Regimes

2013
The two parts of mass balance, inputs and outputs, are now considered together. Budget estimates are provided for Biafo Glacier and from partial data for Batura, Baltoro and some others. Overall quantities reflect the greater moisture availability and mass inputs at high elevations in the Karakoram.

Glacier Mass Balance I: Snowfall and Glacier Nourishment

2013
The inputs to glacier mass balance and phenomena that influence them in the Karakoram are considered in this chapter. Snowfall in the source areas of the glaciers is the first concern. Observations at Biafo Glacier, an Alpine type, offer a rare, relatively detailed quantification of high-altitude snowfall in the accumulation zone.

Near-Term Global Glacier Mass Balance Modelling

2023
Glaciers play a vital role in regulating the earth's climate and have societal as well as scientific significance. Acting as cultural heritage, ecosystem components, water storage and contributors to sea level rise, they have both direct and indirect impact on humanity.

Modelling of Glacier Mass Balance

1993
The energy balance of the ice/snow surface is the dominating factor with regard to mass balance of glaciers in warm environments (currently all ice outside Antarctica). It is shown that an energy balance model is able to generate realistic mass-balance profiles from climate data for glaciers in widely differing climatic settings.

Glacier Mass Balance II: Ablation Losses

2013
The negative or loss factors in mass balance are examined, mainly processes, controls and rates of ablation on glacier surfaces and some other contributors to water yields from glacier basins. Limited but actual ablation measurements exist for three of the large glaciers, Baltoro, Biafo and Batura.

Studies of Glacier Behaviour and Glacier Mass Balance in Greenland—A Review

Geografiska Annaler: Series A, Physical Geography, 1984
Both for local glaciers and for sectors of the Inland Ice, evidence on glacier behaviour is scattered, but work on a glacier inventory of the south-western third of Greenland has furnished a base for future studies on selected glaciers. Nearly all glacier types have been identified among the thousands of local glaciers, including surging and pulsing ...

Dynamics and mass balance of Taylor Glacier, Antarctica: 3. State of mass balance

Journal of Geophysical Research: Earth Surface, 2009
Taylor Glacier flows from the East Antarctic Ice Sheet and terminates in the McMurdo Dry Valleys, where it has left a geomorphologic record of past incursions. Here we use new data on the flow, thickness, and surface balance of Taylor Glacier to calculate ice fluxes and assess the current state of mass balance.

Effective Sample Size for Glacier Mass Balance

Geografiska Annaler, Series A: Physical Geography, 1999
Correlograms from multiple time series of point mass balance, measured on White Glacier (Axel Heiberg Island, Canada) and Abramov Glacier (Alai Range, Kirgizia), show that the correlation decreases with the difference in elevation between the points.

Inferring Glacier Mass Balance Using Radarsat: Results From Peyto Glacier, Canada

Geografiska Annaler, Series A: Physical Geography, 1999
The capability of RADARSAT synthetic aperture radar (SAR) for the purpose of snow-line/accumulation area mapping for a temperate alpine glacier is examined. In agreement with other orbital C-band SAR studies, RADARSAT can discriminate between firn and bare ice facies.

Data assimilation in glacier mass balance modeling

The accurate quantification of glacier mass balance is of vital importance for the evaluation of climate change impact and the management of hydrological resources. However, traditional modeling methodologies on a regional scale are frequently plagued by uncertainties in forcing data, model structure, and parameters.
