Reversed surface-mass-balance gradients on himalayan debris-covered glaciers inferred from remote sensing

Bisset, Rosie R. ; Dehecq, Amaury ; Goldberg, Daniel N. ; Huss, Matthias ; Bingham, Robert G. ; Gourmelen, Noel

In: Remote Sensing, 2020, vol. 12, no. 10, p. 1563

Meltwater from the glaciers in High Mountain Asia plays a critical role in water availability and food security in central and southern Asia. However, observations of glacier ablation and accumulation rates are limited in spatial and temporal scale due to the challenges that are associated with fieldwork at the remote, high-altitude settings of these glaciers. Here, using a...

Detailed detection of active layer freeze-thaw dynamics using quasi-continuous electrical resistivity tomography (Deception Island, Antarctica)

Farzamian, Mohammad ; Vieira, Gonçalo ; Santos, Fernando A. Monteiro ; Tabar, Borhan Yaghoobi ; Hauck, Christian ; Paz, Maria Catarina ; Bernardo, Ivo ; Ramos, Miguel ; Pablo, Miguel Angel de

In: The Cryosphere, 2020, vol. 14, no. 3, p. 1105–1120

Climate-induced warming of permafrost soils is a global phenomenon, with regional and site-specific variations which are not fully understood. In this context, a 2-D automated electrical resistivity tomography (A-ERT) system was installed for the first time in Antarctica at Deception Island, associated to the existing Crater Lake site of the Circumpolar Active Layer Monitoring – South ...

Assessing the potential of soil moisture measurements for regional landslide early warning

Wicki, Adrian ; Lehmann, Peter ; Hauck, Christian ; Seneviratne, Sonia I. ; Waldner, Peter ; Stähli, Manfred

In: Landslides, 2020, p. -

In mountainous terrain, rainfall-induced landslides pose a serious risk to people and infrastructure. Regional landslide early warning systems (LEWS) have proven to be a cost-efficient tool to inform the public about the imminent landslide danger. While most operational LEWS are based on rainfall exceedance thresholds only, recent studies have demonstrated an improvement of the forecast...
