Glacier surges on James Ross Island, Antarctica, and their relationship with climate [PDF]

open access: yesThe Cryosphere
Although the Antarctic Peninsula has a similar climate to that of other regions hosting surge-type glaciers, only one glacier surge has been previously observed in this region.

Glacier Surges and Seasonal Speedups Integrated Into a Single, Enthalpy‐Based Model Framework [PDF]

open access: yesGeophysical Research Letters
Glacier speedups occur on daily to centennial timescales. While basal water and subglacial drainage configuration are thought to drive glacier speedups across these timescales, it remains unclear whether this forcing always occurs through the same ...

Characterization of Three Surges of the Kyagar Glacier, Karakoram

open access: yesRemote Sensing, 2023
Glaciers experience periodic variations in flow velocity called surges, each of which influences the glacier’s characteristics and the occurrence of downstream disasters (e.g., ice-dammed lake outburst floods).

A general theory of glacier surges [PDF]

open access: yesJournal of Glaciology, 2019
We present the first general theory of glacier surging that includes both temperate and polythermal glacier surges, based on coupled mass and enthalpy budgets.

Topographic and hydrological controls on partial and full surges of Little Kluane Glacier, Yukon

open access: yesJournal of Glaciology
We demonstrate that a ~20 km long valley glacier in the St. Elias Mountains, Yukon, can experience both partial and full surges, likely controlled by the presence of a topographic constriction and the formation and drainage of supraglacial lakes.

Kinematics of the exceptionally-short surge cycles of Sít’ Kusá (Turner Glacier), Alaska, from 1983 to 2013

open access: yesJournal of Glaciology, 2021
Glacier surges are periodic episodes of mass redistribution characterized by dramatic increases in ice flow velocity and, sometimes, terminus advance.

Present dynamics and future prognosis of a slowly surging glacier [PDF]

open access: yesThe Cryosphere, 2011
Glacier surges are a well-known example of an internal dynamic oscillation whose occurrence is not a direct response to the external climate forcing, but whose character (i.e.

More dynamic than expected: an updated survey of surging glaciers in the Pamir [PDF]

open access: yesEarth System Science Data, 2020
The investigation of surging glaciers using remote sensing has recently seen a strong increase as freely available satellite data and digital elevation models (DEMs) can provide detailed information about surges that often take place in remote and ...

Changes in ice-surface debris, surface elevation and mass through the active phase of selected Karakoram glacier surges [PDF]

open access: yes, 2022
Surge-type glaciers switch between phases of rapid and slow flow on timescales of a few years to decades. During the active surge phase, large volumes of ice are transported downglacier, creating distinct geomorphological signatures that reflect these ...

Climate and surging of Donjek Glacier, Yukon, Canada

open access: yesArctic, Antarctic, and Alpine Research, 2020
Links between climate and glacier surges are poorly understood but are required to enable prediction of surges and mitigation of associated hazards. Here, we investigate the role of snow accumulation, rain, and temperature on surge periodicity, area ...
