A rapidly retreating, marine-terminating glacier's modeled response to perturbations in basal traction

open access: yesJournal of Glaciology, 2022
Upernavik Isstrøm, a marine glacier undergoing rapid retreat, is simulated by forcing a numerical model with ocean-driven melt. A review of processes driving retreat led us to hypothesize that a glacier undergoing rapid retreat may be less sensitive to ...

Kaolin Model Glaciers [PDF]

open access: yesJournal 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.

From global glacier modeling to catchment hydrology: bridging the gap with the WaSiM-OGGM coupling scheme

open access: yesFrontiers in Water, 2023
Coupled glacio-hydrological models have recently become a valuable method for predicting the hydrological response of catchments in mountainous regions under a changing climate.

Tensile strength of glacial ice deduced from observations of the 2015 eastern Skaftá cauldron collapse, Vatnajökull ice cap, Iceland

open access: yesJournal of Glaciology, 2020
The representation of iceberg calving in numerical models is a key source of uncertainty in century-scale sea-level rise projections. Parameters central to model representations of calving, including the tensile strength of glacier ice, remain poorly ...

Ensemble Kalman Filtering for Glacier Modeling

open access: yesCoRR, 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.

Analysis of the Image of Global Glacier Tourism Destinations from the Perspective of Tourists

open access: yesLand, 2022
Glaciers are attracting increasing attention in the context of climate change, and glacier tourism has also become a popular tourist product. However, few studies have been conducted concerning the image of glacier tourism destinations.

What Can We Learn from Comparing Glacio-Hydrological Models?

open access: yesAtmosphere, 2020
Glacio-hydrological models combine both glacier and catchment hydrology modeling and are used to assess the hydrological response of high-mountain glacierized catchments to climate change. To capture the uncertainties from these model combinations, it is

A new global dataset of mountain glacier centerlines and lengths [PDF]

open access: yesEarth System Science Data, 2022
The length of a glacier is a key determinant of its geometry and is an important parameter in glacier inventories and modeling; glacier centerlines are the lines along which the main flow of glaciers takes place and, thus, are crucial inputs for many ...

Simulation of Historic Glacier Variations with a Simple Climate-Glacier Model [PDF]

open access: yesJournal 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).

Modeling 2m air temperatures over mountain glaciers: Exploring the influence of katabatic cooling and external warming [PDF]

open access: yes, 2015
Air temperature is one of the most relevant input variables for snow and ice melt calculations. However, local meteorological conditions, complex topography, and logistical concerns in glacierized regions make the measuring and modeling of air ...
