From dwindling ice to headwater lakes: could dams replace glaciers in the European Alps?

Farinotti, Daniel ; Pistocchi, Alberto ; Huss, 5 Matthias

In: Environmental Research Letters, 2016, vol. 11, no. 5, p. 54022

The potential exploitation of areas becoming ice-free in response to ongoing climate change has rarely been addressed, although it could be of interest from the water management perspective. Here we present an estimate for the potential of mitigating projected changes in seasonal water availability from melting glaciers by managing runoff through reservoirs. For the European Alps we estimate that...

Re-analysis of seasonal mass balance at Abramov glacier 1968–2014

Barandun, Martina ; Huss, Matthias ; Sold, Leo ; Farinotti, Daniel ; Azisov, Erlan ; Salzmann, Nadine ; Usubaliev, Ryskul ; Merkushkin, Alexandr ; Hoelzle, Martin

In: Journal of Glaciology, 2015, vol. 61, no. 230, p. 1103–1117

Abramov glacier, located in the Pamir Alay, Kyrgyzstan, is a reference glacier within the Global Terrestrial Network for Glaciers. Long-term glaciological measurements exist from 1968 to 1998 and a mass-balance monitoring programme was re-established in 2011. In this study we re-analyse existing mass-balance data and use a spatially distributed mass-balance model to provide continuous seasonal...

A high-resolution bedrock map for the Antarctic Peninsula

Huss, Matthias ; Farinotti, Daniel

In: The Cryosphere, 2014, vol. 8, no. 4, p. 1261–1273

Assessing and projecting the dynamic response of glaciers on the Antarctic Peninsula to changed atmospheric and oceanic forcing requires high-resolution ice thickness data as an essential geometric constraint for ice flow models. Here, we derive a complete bedrock data set for the Antarctic Peninsula north of 70° S on a 100 m grid. We calculate distributed ice thickness based on surface...

The bedrock topography of Starbuck Glacier, Antarctic Peninsula, as determined by radio-echo soundings and flow modeling

Farinotti, Daniel ; King, Edward C. ; Albrecht, Anika ; Huss, Matthias ; Gudmundsson, G. Hilmar

In: Annals of Glaciology, 2014, vol. 55, no. 67, p. 22–28

A glacier-wide ice-thickness distribution and bedrock topography is presented for Starbuck Glacier, Antarctic Peninsula. The results are based on 90 km of ground-based radio-echo sounding lines collected during the 2012/13 field season. Cross-validation with ice-thickness measurements provided by NASA's IceBridge project reveals excellent agreement. Glacier-wide estimates are derived using a...

An upper-bound estimate for the accuracy of glacier volume–area scaling

Farinotti, Daniel ; Huss, Matthias

In: The Cryosphere, 2013, vol. 7, no. 6, p. 1707–1720

Volume–area scaling is the most popular method for estimating the ice volume of large glacier samples. Here, a series of resampling experiments based on different sets of synthetic data is presented in order to derive an upper-bound estimate (i.e. a level achieved only within ideal conditions) for its accuracy. For real-world applications, a lower accuracy has to be expected. We also quantify...

Chemical and Biological Gradients along the Damma Glacier Soil Chronosequence, Switzerland

Bernasconi, Stefano M. ; Bauder, Andreas ; Bourdon, Bernard ; Brunner, Ivano ; Bünemann, Else ; Chris, Iso ; Derungsg, Nicolas ; Edwards, Peter ; Farinotti, Daniel ; Frey, Beat ; Frossard, Emmanuel ; Furrer, Gerhard ; Gierga, Merle ; Göransson, Hans ; Gülland, Kathy ; Hagedorn, Frank ; Hajdas, Irka ; Hindshawc, Ruth ; Ivy-Ochs, Susan ; Jansa, Jan ; Jonas, Tobias ; Kiczkac, Mirjam ; Kretzschmar, Ruben ; Lemarchand, Emmanuel ; Luster, Jörg ; Magnusson, Jan ; Mitchell, Edward A.

Soils are the product of a complex suite of chemical, biological, and physical processes. In spite of the importance of soils for society and for sustaining life on earth, our knowledge of soil formation rates and of the influence of biological activity on mineral weathering and geochemical cycles is still limited. In this paper we provide a description of the Damma Glacier Critical Zone...

Distributed ice thickness and volume of all glaciers around the globe

Huss, Matthias ; Farinotti, Daniel

In: Journal of Geophysical Research, 2012, vol. 117, p. F04010

A new physically based approach for calculating glacier ice thickness distribution and volume is presented and applied to all glaciers and ice caps worldwide. Combining glacier outlines of the globally complete Randolph Glacier Inventory with terrain elevation models (Shuttle Radar Topography Mission/Advanced Spaceborne Thermal Emission and Reflection Radiometer), we use a simple dynamic model to...

Runoff evolution in the Swiss Alps: projections for selected high-alpine catchments based on ENSEMBLES scenario

Farinotti, Daniel ; Usselmann, Stephanie ; Huss, Matthias ; Bauder, Andreas ; Funk, Martin

In: Hydrological Processes, 2011, vol. 25, p. -

The Alps are often referred to as the ‘water tower of Europe’. In Switzerland, many branches of the economy, especially the hydropower industry, are closely linked to and dependent on the availability of water. Assessing the impact of climate change on streamflow runoff is, thus, of great interest. Major efforts have already been made in this respect, but the analyses often focus on...

Snow accumulation distribution inferred from time-lapse photography and simple modelling

Farinotti, Daniel ; Magnusson, Jan ; Huss, Matthias ; Bauder, Andreas

In: Hydrological Processes, 2010, p. -

The spatial and temporal distribution of snow accumulation is complex and significantly influences the hydrological characteristics of mountain catchments. Many snow redistribution processes, such as avalanching, slushflow or wind drift, are controlled by topography, but their modelling remains challenging. In situ measurements of snow accumulation are laborious and generally have a coarse...
