Processes which Distribute Supraglacial Debris on the Khumbu Glacier, Nepal Himalaya

, 1986
The thickness of supraglacial debris on the Khumbu Glacier, Nepal Himalaya, has been mapped by a combination of direct measurements and morphological and lithological studies.

Spatial, seasonal and interannual variability of supraglacial ponds in the Langtang Valley of Nepal, 1999–2013

Journal of Glaciology, 2017
Supraglacial ponds play a key role in absorbing atmospheric energy and directing it to the ice of debris-covered glaciers, but the spatial and temporal distribution of these features is not well documented.

Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal

, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

Reduced Future Summer Water Availability in the Tien Shan Due To Glacier Wastage

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Glaciers in the Tien Shan mountains of Central Asia are a crucial source of freshwater for agriculture and local communities, sustaining over 100 million people in the region. Here, we project future water availability for this region by dynamically modeling the evolution of all glaciers and merging their runoff with hydrological runoff ...

Soft‐bedded ice sheet in hummocky terrain of north‐central Poland: Origin of rim ridges and subglacial processes

Sedimentology, Volume 73, Issue 2, Page 540-559, February 2026.
ABSTRACT Hummocky terrains are characterised by various geomorphological features that typically record processes associated with the downwasting of ice sheets. Common landforms in these areas include ramparts, linear ridges, kettle holes and ice‐walled lake plains.

Air temperature distribution and energy balance modelling of a debris-covered glacier

, 2016
Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

Thickness estimation of supraglacial debris above ice cliff exposures using a high-resolution digital surface model derived from terrestrial photography

Journal of Glaciology, 2017
The thickness of supraglacial debris cover controls how it impacts the ablation rate of underlying glacier ice, yet this quantity remains challenging to measure, particularly at glacier scales.

Phosphatase activity and organic phosphorus turnover on a high Arctic glacier [PDF]

Biogeosciences, 2009
Arctic glacier surfaces harbour abundant microbial communities consisting mainly of heterotrophic and photoautotrophic bacteria. The microbes must cope with low concentrations of nutrients and with the fact that both the dissolved and debris-bound ...

Comment: a test of the englacial thrusting hypothesis of ;hummocky' moraine formation [PDF]

, 2007
Areas of apparently chaotically organised moraine mounds and ridges are commonly associated with British Younger Dryas glaciers, and are also found at many contemporary glacier margins (Boulton & Eyles 1979; Benn 1992; Bennett & Boulton 1993b; Hambrey et
