Glacier hydrology in Svalbard, Norwegian high arctic

Quaternary Science Reviews, 1997
Abstract Progress in glacier hydrology has focused on temperate glaciers, although partly or wholly non-temperate glaciers are found in many parts of the world, and significant areas of former ice sheets were probably non-temperate. It has usually been assumed that drainage from non-temperate glaciers consists of relatively dilute and invariable ...

Glacier mass budget measurements by hydrologic means

Water Resources Research, 1966
Ice storage changes for the South Cascade Glacier drainage basin were determined for the 1957–1964 period using basin runoff and precipitation measurements. Measurements indicate that evaporation and condensation are negligible compared with the large runoff and precipitation values.

A revised Canadian perspective: progress in glacier hydrology

Hydrological Processes, 2005
AbstractCurrent research into glacier hydrology is occurring at a time when glaciers around the world, particularly those whose hydrological regimes affect populated areas, are shrinking as they go through a state of perpetual negative annual mass balance.

Hydrologic monitoring of supercooled meltwater from Icelandic glaciers

Quaternary Science Reviews, 2005
Knowledge of how glaciers entrain sediment is central to understanding processes of glacier movement and products of glacial sediment deposition. Previous work has shown that if the total hydraulic potential of subglacial meltwater increases more rapidly than the resulting mechanical energy can be transformed into sensible heat, then supercooling and ...

A multicomponent coupled model of glacier hydrology

2009
Multiple lines of evidence suggest a causal link between subglacial hydrology and phenomena such as fast-flowing ice. This evidence includes a measured correlation between water under alpine glaciers and their motion, the presence of saturated sediment beneath Antarctic ice streams, and geologic signatures of enhanced paleo-ice flow over deformable ...

Glacier hydrology and the potential for subglacial karstification

Norsk Geografisk Tidsskrift - Norwegian Journal of Geography, 1984
Contemporary models of subglacial hydrology identify two quasi-independent hydrologic systems at the bed of temperate alpine glaciers: a dendritic, low pressure conduit network and a more extensive, high pressure regelation film. Observations in Castleguard Cave beneath the Columbia Icefield suggest that this distinction continues into the groundwater ...

The eco-hydrology of glacier surfaces

2019
Recent work has highlighted the importance of the so-called “weathering crust” as a microbially and hydrologically active layer on glacier surfaces. However, this layer is yet to undergo investigation, with no estimates of water, microbial or nutrient fluxes through it to downstream freshwater and marine ecosystems.
