Position dependent velocity profiles in granular avalanches
We present velocity profile measurements in granular avalanches flowing down a flat chute with wide rectangular cross section. The flow is recorded through a transparent side-wall by a high-speed camera, which...

Density variations in dry granular avalanches
Dry granular avalanches exhibit bulk density variations. Understanding the physical mechanisms behind these density variations is especially important in the study of geophysical flows such as snow and rock av...

Dynamics of an outburst flood originating from a small and high-altitude glacier in the Arid Andes of Chile
Glacial lake outburst floods (GLOFs) are common where highly dynamic temperate glaciers exist, since seasonal changes in ice-conduit dynamics can start rapid lake drainages. Lakes dammed by cold-based glaciers...

Glacier protection laws: Potential conflicts in managing glacial hazards and adapting to climate change
The environmental, socioeconomic and cultural significance of glaciers has motivated several countries to regulate activities on glaciers and glacierized surroundings. However, laws written to specifically pro...

Open AccessSubglacial discharge controls seasonal variations in the thermal structure of a glacial lake in Patagonia
Water temperature in glacial lakes affects underwater melting and calving of glaciers terminating in lakes. Despite its importance, seasonal lake temperature variations are poorly understood because taking lon...

Open AccessThe foundations of the Patagonian icefields
The two vast Patagonian icefields are a global hotspot for ice-loss. However, not much is known about the total ice volume they store - let alone its spatial distribution. One reason is that the abundant recor...
