Temporal downscaling of glaciological mass balance using seasonal observations

Journal of Glaciology, 2023
Glaciological mass-balance measurements have been the backbone of internationally coordinated glacier monitoring. The resulting annual observations have been used to understand glacier reactions to climate change, and to assess both regional and global ...

Glacier projections sensitivity to temperature-index model choices and calibration strategies

Annals of Glaciology, 2023
The uncertainty of glacier change projections is largely influenced by glacier models. In this study, we focus on temperature-index mass-balance (MB) models and their calibration.

Elevation-Dependent Glacier Albedo Modelling Using Machine Learning and a Multi-Algorithm Satellite Approach in Svalbard

Remote Sensing
Glacier surface albedo controls solar energy absorption and Arctic mass balance, yet comprehensive modelling approaches remain limited. This study develops and validates multiple modelling frameworks for glacier albedo prediction using automatic weather ...

A Model for Sedimentation by Tidewater Glaciers [PDF]

Annals of Glaciology, 1981
Sampling of sediment from the fjord floor in front of tidewater glaciers in Glacier Bay, Alaska, has provided information about processes in this restricted glacimarine (Dreimanis 1979) setting. Sediment sampling, in conjunction with oceanographic and glacial dynamics data, has also enabled the discrimination of sediment types and their facies ...

Modeling Ablation on Place Glacier, British Columbia, from Glacier and Off-glacier Data Sets [PDF]

Arctic, Antarctic, and Alpine Research, 2009
Abstract The results of two simulations of hourly ablation, from late July to September 2002, at a site on the Place Glacier are described. First, ablation is modeled from a data set collected at the glacier site; second, from a data set collected off-glacier at a site below the glacier tongue.

Advance and thickening of the tidewater outlet glacier Eqalorutsit Kangilliit Sermiat surrounded by the thinning southern Greenland ice sheet

Journal of Glaciology
Although most Greenland glaciers have undergone thinning and frontal retreat in recent decades, the tidewater glacier Eqalorutsit Kangilliit Sermiat in South Greenland departs from this regional pattern.

Modelling Glaciers in the HARMONIE-AROME NWP model [PDF]

Advances in Science and Research, 2017
Abstract. HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multi-purpose SURFEX surface model. It is developed for high resolution (1–3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we

Initiation of a major calving event on the Bowdoin Glacier captured by UAV photogrammetry [PDF]

The Cryosphere, 2017
In this paper, we analyse the calving activity of the Bowdoin Glacier, north-western Greenland, in 2015 by combining satellite images, UAV (unmanned aerial vehicle) photogrammetry and ice flow modelling.

On non-dimensional forms of basal sliding laws and flow laws for ice-sheet and glacier modelling

Journal of Glaciology
Ice sheets and glaciers flow through basal sliding and internal deformation, each governed by physical laws commonly expressed as power-law relations. These formulations include coefficients—the sliding coefficient and rate factor—whose values and units ...

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier

Biological Reviews
ABSTRACTGlaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.
