Optical determination of snow density via sub-surface scattering

Communications Physics
The physical properties of snow, such as its stiffness, reflectivity, and thermal conductivity, are critical components in feedback processes of the Earth’s system and useful proxies for various applications in environmental science, ranging from ...

Snow in a very steep rock face: accumulation and redistribution during and after a snowfall event

Frontiers in Earth Science, 2015
Terrestrial laser scanning was used to measure snow thickness changes (perpendicular to the surface) in a rock face. The aim was to investigate the accumulation and redistribution of snow in extremely steep terrain (>60°).

A casting method using contrast-enhanced diethylphthalate for micro-computed tomography of snow

Journal of Glaciology, 2021
Casting snow is necessary to prevent metamorphism and deformation prior to X-ray micro-computed tomography (μCT) imaging. Current methods are insufficient for large-scale field sampling of snow due to safety considerations associated with the casting ...

On the relation between avalanche occurrence and avalanche danger level [PDF]

The Cryosphere, 2020
In many countries with seasonally snow-covered mountain ranges warnings are issued to alert the public about imminent avalanche danger, mostly employing an ordinal, five-level danger scale.

Heat, Health and Holidays: Reported Heat Related Adjustments to Australian Tourist Behaviour

International Journal of Climatology, EarlyView.
This study assessed how climate‐related hazards affect Australian tourists' travel planning. While 80% of tourists report no impact, the 20% who do experience disruption most commonly change their activities, timing, or destination, with heat and rain affecting the same proportion of tourists across beach, city, nature, and family tourism types ...

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]

, 2016
Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Deep ice layer formation in an alpine snowpack: monitoring and modeling [PDF]

The Cryosphere, 2020
Ice layers may form deep in the snowpack due to preferential water flow, with impacts on the snowpack mechanical, hydrological and thermodynamical properties.

A talus rock glacier in Nantlle Valley, North Wales

Journal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and
