Rock glaciers on the run – understanding rock glacier landform evolution and recent changes from numerical flow modeling [PDF]

open access: yesThe 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.

A unified model for transient subglacial water pressure and basal sliding

open access: yesJournal of Glaciology, 2022
Changes in water pressure at the beds of glaciers greatly modify their sliding rate, affecting rates of ice mass loss and sea level change. However, there is still no agreement about the physics of subglacial sliding or how water affects it.

Meltwater Intrusions Reveal Mechanisms for Rapid Submarine Melt at a Tidewater Glacier [PDF]

open access: yes, 2019
Submarine melting has been implicated as a driver of glacier retreat and sea level rise, but to date melting has been difficult to observe and quantify. As a result, melt rates have been estimated from parameterizations that are largely unconstrained by ...

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

open access: yesArctic, 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.

Contrasts in the response of adjacent fjords and glaciers to ice-sheet surface melt in West Greenland

open access: yesAnnals of Glaciology, 2016
Neighboring tidewater glaciers often exhibit asynchronous dynamic behavior, despite relatively uniform regional atmospheric and oceanic forcings. This variability may be controlled by a combination of local factors, including glacier and fjord geometry ...

Including debris cover effects in a distributed model of glacier ablation [PDF]

open access: yes, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

A Hierarchical Spatio-Temporal Statistical Model Motivated by Glaciology [PDF]

open access: yes, 2019
In this paper, we extend and analyze a Bayesian hierarchical spatio-temporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...

Suitability of a constant air temperature lapse rate over an Alpine glacier: testing the Greuell and Böhm model as an alternative [PDF]

open access: yes, 2013
Near-surface air temperature, typically measured at a height of 2 m, is the most important control on the energy exchange and the melt rate at a snow or ice surface.

Estimating the characteristics of runoff inflow into Lake Gojal in ungauged, highly glacierized upper Hunza River Basin, Pakistan [PDF]

open access: yes, 2013
Motivated by the potential flood outburst of Lake Gojal in the ungauged highly glacierized (27%) upper Hunza River Basin (HRB) in Pakistan that was dammed by a massive landslide on 4 January 2010, we attempt to analyze the characteristics of water inflow

Controls on the diurnal streamflow cycles in two subbasins of an alpine headwater catchment [PDF]

open access: yes, 2015
In high-altitude alpine catchments, diurnal streamflow cycles are typically dominated by snowmelt or ice melt. Evapotranspiration-induced diurnal streamflow cycles are less observed in these catchments but might happen simultaneously.
