Fate of glacier surface snow‐originating bacteria in the glacier‐fed hydrologic continuums
Environmental Microbiology, 2021Summary Glaciers represent important biomes of Earth and are recognized as key species pools for downstream aquatic environments. Worldwide, rapidly receding glaciers are driving shifts in hydrology, species distributions and threatening microbial diversity in glacier‐fed aquatic ecosystems. However, the impact of glacier surface snow‐

Glacier-permafrost hydrological interconnectivity: Stagnation Glacier, Bylot Island, Canada
Geological Society, London, Special Publications, 2005Abstract The complex thermal structure in areas where polythermal glaciers and continuous permafrost are present increases the potential for direct linkages between subsurface water conduits within glaciers and permafrost. In this study, hydrologic features of a glacier and the surrounding ice-cored moraines were examined and the potential ...

A hydrological approach to estimating daily glacier ablation
Canadian Journal of Earth Sciences, 2016Reduced meltwater discharge owing to glacier retreat can have severe impacts on downstream water users. To assess these impacts, it is essential to differentiate between water from glacier melt and other sources. We propose a method for doing this on a daily time scale by applying a mixing law to electrical conductivity and proglacial discharge ...

Glacier hydrology in Svalbard, Norwegian high arctic
Quaternary Science Reviews, 1997Abstract 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, 1966Ice 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.

Progress in glacier hydrology: a Canadian perspective
Hydrological Processes, 2000Glacier variations are signals of global change. Current estimates are that ice is being lost from small glaciers of the world at the rate of approximately 130 mm year -1 and that the impact of this alone would be to change sea level upward, by 0.25 mm year -1 .

Hydrologic monitoring of supercooled meltwater from Icelandic glaciers
Quaternary Science Reviews, 2005Knowledge 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
2009Multiple 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 ...
