Simulation, modeling and authoring of glaciers [PDF]
ACM Transactions on Graphics, 2020 Glaciers are some of the most visually arresting and scenic elements of cold regions and high mountain landscapes. Although snow-covered terrains have previously received attention in computer graphics, simulating the temporal evolution of glaciers as well as modeling their wide range of features has never been addressed.

, 2007 Calibration and validation of glacier mass balance models typically rely on mass balance data derived from measurements at individual points, often along altitudinal gradients, thus neglecting much of the spatial variability of mass balance.

Thermal structure and basal sliding parametrisation at Pine Island Glacier – a 3-D full-Stokes model study [PDF]
The Cryosphere, 2015 Pine Island Glacier is one of the fastest changing glaciers of the Antarctic Ice Sheet and therefore of scientific interest. The glacier holds enough ice to raise the global sea level significantly (~ 0.5 m) when fully melted.

Journal of Glaciology, 1955 AbstractA mixture of approximately one part of water to two parts of kaolin (china clay) has proved suitable for making model glaciers on scales between 1 : 1000 and 1 : 10,000. The kaolin “glaciers” crevasse and flow realistically, and slide on their beds.

Future high-mountain hydrology: a new parameterization of glacier retreat [PDF]
Hydrology and Earth System Sciences, 2010 Global warming is expected to significantly affect the runoff regime of mountainous catchments. Simple methods for calculating future glacier change in hydrological models are required in order to reliably assess economic impacts of changes in the water ...

A Bayesian ice thickness estimation model for large-scale applications
Journal of Glaciology, 2020 Accurate estimations of ice thickness and volume are indispensable for ice flow modelling, hydrological forecasts and sea-level rise projections. We present a new ice thickness estimation model based on a mass-conserving forward model and a Bayesian ...

Ensemble Kalman Filtering for Glacier Modeling
CoRR, 2022 Working with a two-stage ice sheet model, we explore how statistical data assimilation methods can be used to improve predictions of glacier melt and relatedly, sea level rise. We find that the EnKF improves model runs initialized using incorrect initial conditions or parameters, providing us with better models of future glacier melt.

Simulation of Historic Glacier Variations with a Simple Climate-Glacier Model [PDF]
Journal of Glaciology, 1988 AbstractGlacier variations during the last few centuries have shown a marked coherence over the globe. Characteristic features are the maximum stand somewhere in the middle of the nineteenth century, and the steady retreat afterwards (with some minor interruptions depending on the particular region).

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Journal of Glaciology, 2023 Calculation of the calving loss of tidewater glaciers depends on accurate bedrock information. In regional to global-scale projections of future tidewater glacier evolution this dependence is problematic.
