Over-winter persistence of supraglacial lakes on the Greenland Ice Sheet: results and insights from a new model

open access: yesJournal of Glaciology, 2020
We present a newly developed 1-D numerical energy-balance and phase transition supraglacial lake model: GlacierLake. GlacierLake incorporates snowfall, in situ snow and ice melt, incoming water from the surrounding catchment, ice lid formation, basal ...

The role of subglacial hydrology in Antarctic ice sheet dynamics and stability: a modelling perspective

open access: yesAnnals of Glaciology, 2022
Subglacial hydrology is an important component of the ice dynamic system in Antarctica but is challenging to investigate due to the large spatial scales of the catchment systems, the ice thickness, and remote location.

Crater glaciers on active volcanoes: Hydrological anomalies [PDF]

open access: yesEos, Transactions American Geophysical Union, 2005
Mount St. Helens is an active volcano that hosts glacier ice within its crater. Although the common picture of volcano/glacier interactions is one of rapid meltwater generation when hot material is brought into contact with snow and ice [e.g.,Major and Newhall, 1989], there have been practically no observable hydrological consequences of the ongoing ...

Do debris-covered glaciers demonstrate distinctive hydrological behaviour compared to clean glaciers? [PDF]

open access: yesJournal of Hydrology, 2019
Supraglacial debris is known to strongly influence the distribution of glacier surface melt. Since melt inputs drive the formation and evolution of glacial drainage systems, it should follow that the drainage systems of debris-covered glaciers will differ from those of debris-free glaciers. This would have implications for the proglacial runoff regime,

GIS based landslide susceptibility mapping of northern areas of Pakistan, a case study of Shigar and Shyok Basins

open access: yesGeomatics, Natural Hazards & Risk, 2017
This study presents the use of geographical information system (GIS) datasets and methods to investigate landslide susceptibility in the rugged mountainous terrain of Shigar and Shyok Basins in northern areas of Pakistan.

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

open access: yesAdvances 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).

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Isotope Hydrograph Separation Reveals Rainfall on the Glaciers Will Enhance Ice Meltwater Discharge to the Himalayan Rivers

open access: yesWater Resources Research
The Indian Summer Monsoon (ISM) and meltwater from the Himalayan are the two most important sources of water in the Indian subcontinent. However, the impact of ISM on Himalayan glaciers and subsequent stream hydrology remains largely unknown.

Simulating seasonal evolution of subglacial hydrology at a surging glacier in the Karakoram

open access: yesJournal of Glaciology
Glacier motion, retreat and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that ...
