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

Surges of Harald Moltke Bræ, north-western Greenland: seasonal modulation and initiation at the terminus [PDF]
The Cryosphere, 2021 Harald Moltke Bræ, a marine-terminating glacier in north-western Greenland, shows episodic surges. A recent surge from 2013 to 2019 lasted significantly longer (6 years) than previously observed surges (2–4 years) and exhibits a pronounced seasonality ...

A new inventory of High Mountain Asia surging glaciers derived from multiple elevation datasets since the 1970s [PDF]
Earth System Science Data, 2023 Glacier surging is an unusual instability of ice flow, and inventories of surging glaciers are important for regional glacier mass balance studies and glacier dynamic studies. Glacier surges in High Mountain Asia (HMA) have been widely reported. However,

Enthalpy balance theory unifies diverse glacier surge behaviour
Annals of Glaciology, 2022 It is commonly asserted that there are two distinct classes of glacier surges: slow, long-duration ‘Svalbard-type’ surges, triggered by a transition from cold- to warm-based conditions (thermal switching), and fast, shorter-duration ‘Alaska-type’ surges ...

Brief communication: Detection of glacier surge activity using cloud computing of Sentinel-1 radar data [PDF]
The Cryosphere, 2021 For studying the flow of glaciers and their response to climate change it is important to detect glacier surges. Here, we compute within Google Earth Engine the normalized differences between winter maxima of Sentinel-1 C-band radar backscatter image ...

Journal 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]
The 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]
Earth 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 ...

Surge-type and surge-modified glaciers in the Karakoram [PDF]
Scientific Reports, 2017 AbstractGlaciers in the Karakoram exhibit irregular behavior. Terminus fluctuations of individual glaciers lack consistency and, unlike other parts of the Himalaya, total ice mass remained stable or slightly increased since the 1970s. These seeming anomalies are addressed through a comprehensive mapping of surge-type glaciers and surge-related impacts,

Surging glaciers in Scotland [PDF]
Scottish Geographical Journal, 2021 Glacier surges are cyclic oscillations of velocity and mass resulting from internal dynamic instabilities.
