Intermittent structural weakening and acceleration of the Thwaites Glacier Tongue between 2000 and 2018 [PDF]

open access: yes, 2020
Evolving conditions at the terminus of Thwaites Glacier will be important in determining the rate of its future sea-level contribution over the coming decades.

Modeled Climate-Induced Glacier Change in Glacier National Park, 1850–2100 [PDF]

open access: yesBioScience, 2003
consequences of glacier retreat by creating spatially explicit models of the creation and ablation of glaciers and of the response of vegetation to climate change. We determined the melt rate and spatial distribution of glaciers under two possible future climate scenarios, one based on carbon dioxide‐induced global warming and the other on a linear ...

Sensitivity of grounding line dynamics to the choice of the friction law

open access: yesJournal of Glaciology, 2017
Basal slip accounts for a large part of the flow of ice streams draining ice from Antarctica and Greenland into the ocean. Therefore, an appropriate representation of basal slip in ice flow models is a prerequisite for accurate sea level rise projections.

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

open access: yes, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Modelling accumulation of a high-altitude Himalayan glacier

open access: yesJournal of Glaciology
Glacier mass-balance modelling relies on parameterizations to distribute meteorological variables such as precipitation and air temperature over glacier surfaces.

Glacial lake outburst flood hazard assessment by satellite Earth observation in the Himalayas (Chomolhari area, Bhutan) [PDF]

open access: yesGeographica Helvetica, 2019
A case study of glacial lakes outburst flood (GLOF) hazard assessment by satellite Earth observation (EO) and numerical modelling is presented for the supraglacial and ice-contact lakes on Thangothang Chhu glacier, Chomolhari area (Bhutan).

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Experiments with model glaciers

open access: yesGeographical Review of Japan, 1926
A piece of apparatus was designed with which it was hoped to determine the relative rates at which glacier ice would respond by flow to the same head at varying depth pressures. The primary object of the experiments was frustrated, but measurements were secured which permitted the plotting of a curve showing the approximate relation of rate of flow and

The impact of a seasonally ice free Arctic Ocean on the temperature, precipitation and surface mass balance of Svalbard [PDF]

open access: yes, 2012
The observed decline in summer sea ice extent since the 1970s is predicted to continue until the Arctic Ocean is seasonally ice free during the 21st Century. This will lead to a much perturbed Arctic climate with large changes in ocean surface energy flux.

Coupling a global glacier model to a global hydrological model prevents underestimation of glacier runoff

open access: yesHydrology and Earth System Sciences, 2022
Abstract. Global hydrological models have become a valuable tool for a range of global impact studies related to water resources. However, glacier parameterization is often simplistic or non-existent in global hydrological models. By contrast, global glacier models do represent complex glacier dynamics and glacier evolution, and as such, they hold the ...
