Glacial water: a dynamic microbial medium
Microbial communities and nutrient dynamics in glaciers and ice sheets continuously
change as the hydrological conditions within and on the ice change. Glaciers and ice sheets …

Hydraulic reconstruction of the 1818 Giétro glacial lake outburst flood
In the spring of 1818, ice avalanches from the Giétro Glacier created an ice dam, which in
turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its …

[HTML][HTML] Drainage of an ice-dammed lake through a supraglacial stream: hydraulics and thermodynamics
The glacier-dammed Lac des Faverges, located on Glacier de la Plaine Morte (Swiss Alps),
has drained annually as a glacier lake outburst flood since 2011. In 2018, the lake volume …

Knickzone Extraction Tool (KET)–A new ArcGIS toolset for automatic extraction of knickzones from a DEM based on multi-scale stream gradients
Extraction of knickpoints or knickzones from a Digital Elevation Model (DEM) has gained
immense significance owing to the increasing implications of knickzones on landform …

Structural characteristics of flow units in Svalbard valley glaciers and their utility for investigating ice-dynamic changes over centennial timescales
The aim of this paper is to characterise the internal structures and ice-flow history of
representative valley glaciers in Svalbard, and infer from them dynamic changes over …

[HTML][HTML] Geomorphological and morphometric characterization of subglacial channels on Devon Island, Nunavut, Canada
SF Ruso, AG Galofre, GR Osinski - Geomorphology, 2024 - Elsevier
Subglacial channels are morphologically and morphometrically distinct in comparison to
fluvial channels, yet their identification from remote sensing data is still problematic. To …

Modeling the influence of moulin shape on subglacial hydrology
Subglacial models represent moulins as cylinders or cones, but field observations suggest
that the upper part of moulins in the Greenland Ice Sheet has more complex shapes. These …
