Ice‐Dynamical Glacier Evolution Modeling—A Review
Reviews of Geophysics, 2022 AbstractGlaciers play a crucial role in the Earth System: they are important water suppliers to lower‐lying areas during hot and dry periods, and they are major contributors to the observed present‐day sea‐level rise. Glaciers can also act as a source of natural hazards and have a major touristic value.

Estimating large scale dynamic mountain glacier states with numerical modelling and data assimilation [PDF]
The Cryosphere, 2022 Abstract. A large majority of the direct observational record for glacier changes falls within the post-industrial period, associated with global glacier retreat. Given this availability of data, and significant focus in contemporary glacier modelling falling on post-industrial retreat, glacier models are typically calibrated using – and validated with

Rock glaciers on the run – understanding rock glacier landform evolution and recent changes from numerical flow modeling [PDF]
The Cryosphere, 2016 Rock glaciers are landforms that form as a result of creeping mountain permafrost which have received considerable attention concerning their dynamical and thermal changes.

Mutual effects of ablation and ice temperature in a firn-free glacier: Observations from Aug 1st glacier on northeast Tibetan plateau [PDF]
iScienceSummary: Glacier stability depends on the interaction between ice temperature and ablation, processes mediated by firn cover. Although firn-covered glaciers have been extensively investigated, firn-free glacier dynamics remain less clear.

Assessing glacier changes and hydrological impacts in the upper Indus Basin under CMIP6 climate scenarios [PDF]
iScienceSummary: Glaciers in the Himalaya are vital for sustaining streamflow in the Upper Indus Basin. This study quantifies future glacier mass and area changes in the Jhelum sub-basin using projections from 13 bias-corrected CMIP6 climate models under SSP245 ...

Monte Carlo ice flow modeling projects a new stable configuration for Columbia Glacier, Alaska, c. 2020 [PDF]
The Cryosphere, 2012 Due to the abundance of observational datasets collected since the onset of its retreat (c. 1983), Columbia Glacier, Alaska, provides an exciting modeling target.

Ensemble Kalman Filtering for Glacier Modeling [PDF]
arXiv.org, 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

Inferring time-dependent calving dynamics at Helheim Glacier
Journal of Glaciology, 2023 We perform Bayesian inference of the parameters of a time-dependent model of ice flow and calving at Helheim Glacier, East Greenland. We find that, while a time-independent calving parameterization can recover the mean observed terminus position, such a ...
