Evaluating glacier surges in Karakoram region using earth observation data [PDF]
Data in Brief, 2020 A glacier is said to be in a state of surge if it has abnormally high velocity and advances very rapidly (10–100 times faster than normal) in a short period of time (lasting few months to a few years).

Automated Detection of Glacier Surges from Sentinel-1 Surface Velocity Time Series—An Example from Svalbard [PDF]
Remote Sensing, 2023 Even though surge-type glaciers make up only a small percentage of all glaciers, related research contributes considerably to the general understanding of glacier flow mechanisms.

Observed positive feedback between surface ablation and crevasse formation drives glacier acceleration and potential surge [PDF]
Nature CommunicationsSudden glacier acceleration and instability, e.g. surges, strongly influence glacier ice loss. However, lack of in-situ observations of the involved processes hampers our ability to understand, quantify and model such a role.

Remote Sensing, 2019 Collapsing valley glaciers leaving their bed to rush down a flat hill slope at the speed of a racing car are so far rare events. They have only been reported for the Kolkaglacier (Caucasus) in 2002 and the two glaciers in the Aru mountain range (Tibet ...

Geomatics, Natural Hazards and Risk, 2021 We observed the surge velocity, terminus advance, lake formation and outburst, as well as its downstream impacts at Shisper Glacier in the Karakoram, Pakistan and suggest potential nature-based risk-reduction solutions.

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 ...
