Melting of the glacier base during a small-volume subglacial rhyolite eruption: evidence from Blahnukur, Iceland. [PDF]

, 2002
Although observations of recent volcanic eruptions beneath Vatnajokull, Iceland have improved the understanding of ice deformation and meltwater drainage, little is known about the processes that occur at the glacier base.

Seasonal variability in ice velocity driven by subglacial hydrology of Drang Drung Glacier, Western Himalayas

Journal of Glaciology
Seasonal glacier dynamics are key to predicting hazards and glacier stability due to short-term events as well as improving glacier models. However, the short-term ice velocity variations remain poorly constrained for slow-moving glaciers in the Himalaya

A model of water extraction from the subglacial hydrologic system under idealized conditions [PDF]

The Cryosphere
Subglacial water modulates glacier velocity across a wide range of space and time scales by influencing friction at the glacier bed. Observations show ice acceleration due to supraglacial lake drainage and water draining through moulins, where both ...

Future high-mountain hydrology: a new parameterization of glacier retreat [PDF]

Hydrology and Earth System Sciences, 2010
Abstract. Climate warming is expected to significantly affect the runoff regime of mountainous catchments. Simple methods for calculating future glacier change in hydrological models are required in order to efficiently project economic impacts of changes in the water cycle over the next decades.

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, EarlyView.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

The dual role of meltwater in buffering river runoff in the Yarlung Zangbo Basin, Tibetan Plateau

Journal of Hydrology: Regional Studies
Study region: The Yarlung Zangbo Basin (YZB) on the Tibetan Plateau, the world's highest river basin, features a significant cryosphere with glaciers and seasonal snow cover crucial to its hydrology.

Rapid mass loss and disappearance of summer-accumulation type hanging glacier

Advances in Climate Change Research, 2022
Hanging glaciers hold the absolute dominant number in West China and their changes had important influences on local hydrology, sea-level rise and natural hazards (snow/ice avalanches).

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change [PDF]

, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.
