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...

The European mountain cryosphere: a review of its current state, trends, and future challenges

Beniston, Martin ; Farinotti, Daniel ; Stoffel, Markus ; Andreassen, Liss M. ; Coppola, Erika ; Eckert, Nicolas ; Fantini, Adriano ; Giacona, Florie ; Hauck, Christian ; Huss, Matthias ; Huwald, Hendrik ; Lehning, Michael ; López-Moreno, Juan-Ignacio ; Magnusson, Jan ; Marty, Christoph ; Morán-Tejéda, Enrique ; Morin, Samuel ; Naaim, Mohamed ; Provenzale, Antonello ; Rabatel, Antoine ; Six, Delphine ; Stötter, Johann ; Strasser, Ulrich ; Terzago, Silvia ; Vincent, Christian

In: The Cryosphere, 2018, vol. 12, no. 2, p. 759–794

The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution. We additionally provide an assessment of current cryosphere research in Europe and point to the different...

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...

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...

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...

A consensus estimate for the ice thickness distribution of all glaciers on Earth

Farinotti, Daniel ; Huss, Matthias ; Fürst, Johannes J. ; Landmann, Johannes ; Machguth, Horst ; Maussion, Fabien ; Pandit, Ankur

In: Nature Geoscience, 2019, vol. 12, no. 3, p. 168–173

Knowledge of the ice thickness distribution of the world’s glaciers is a fundamental prerequisite for a range of studies. Projections of future glacier change, estimates of the available freshwater resources or assessments of potential sea-level rise all need glacier ice thickness to be accurately constrained. Previous estimates of global glacier volumes are mostly based on scaling...

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...

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...

The bedrock topography of Gries- and Findelengletscher

Feiger, Nadine ; Huss, Matthias ; Leinss, Silvan ; Sold, Leo ; Farinotti, Daniel

In: Geographica Helvetica, 2018, vol. 73, no. 1, p. 1–9

Knowledge of the ice thickness distribution of glaciers is important for glaciological and hydrological applications. In this contribution, we present two updated bedrock topographies and ice thickness distributions for Gries- and Findelengletscher, Switzerland. The results are based on ground-penetrating radar (GPR) measurements collected in spring 2015 and already-existing data. The GPR...

In: Geoscientific Instrumentation, Methods and Data Systems, 2017, vol. 6, no. 2, p. 397–418

Glacier mass loss is among the clearest indicators of atmospheric warming. The observation of these changes is one of the major objectives of the international climate monitoring strategy developed by the Global Climate Observing System (GCOS). Long-term glacier mass balance measurements are furthermore the basis for calibrating and validating models simulating future runoff of glacierised...
