Distributed acoustic sensing of microseismic sources and wave propagation in glaciated terrain

open access: yesNature Communications, 2020
In this study, Walter and colleagues deploy a 1 km long fiber optics cable on a glacier surface. Via the use of distributed acoustic sensing, the authors are capable of monitoring glacier dynamics and Alpine mass movements.

Remote Detection of Surge-Related Glacier Terminus Change across High Mountain Asia

open access: yesRemote Sensing, 2021
High Mountain Asia (HMA) hosts the largest glacier concentration outside of polar regions. It is also distinct glaciologically as it forms one of two major surge clusters globally, and many glaciers there contradict the globally observed glacier ...

Annotated bibliography of the Russian languages literature on glaciology for 2018

open access: yesЛëд и снег, 2020
The proposed annual bibliography continues annotated lists of the Russian-language literature on glaciology that were regularly published in the past. It includes 297 references grouped into the following ten sections: 1)  general issues of glaciology; 2)

A Generalized Interpolation Material Point Method for Shallow Ice Shelves. 2: Anisotropic Nonlocal Damage Mechanics and Rift Propagation

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Ice shelf fracture is responsible for roughly half of Antarctic ice mass loss in the form of calving and can weaken buttressing of upstream ice flow.

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Mass balance of glacier No. 139 in the basin of Lake Karakul in the Eastern Pamirs

open access: yesCentral Asian Journal of Water Research, 2022
Mountain glaciers, including the poorly examined glaciers of Lake Karakul Basin, are considered the most vulnerable part of the cryosphere directly reacting to the changing climatic conditions.

A note on hysteresis in glaciology

open access: yesApplied Mathematics Letters, 2000
Recent studies on the mechanism governing the Laurentide ice sheet oscillations of the Last Ice Age focus on the most critical effect of the basal hydraulic processes enhanced when the ice is sliding along soft deformable beds. To understand the import of this, we consider {A. C. Fowler} and \textit{C. Johnson}'s 0-D hydrological flow model [J. Glaciol.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Control of Ocean Temperature on Jakobshavn Isbræ's Present and Future Mass Loss

open access: yesGeophysical Research Letters, 2018
Large uncertainties in model parameterizations and input data sets make projections of future sea level rise contributions of outlet glaciers challenging.

The Queen of the Arctic: Louise Arner Boyd

open access: yesPolar Research, 2023
Louise Boyd (1887–1972) was a female pioneer in Arctic research whose legacy includes the exploration of north-east Greenland. In this Perspective piece, we use a broad interdisciplinary approach to investigate her career as a photographer and expedition
