The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem

Massimo Bourquin

Glacier-fed streams are the cold, ultra-oligotrophic, and unstable streams that are fed by glacial meltwater. Despite these extreme conditions, they harbour a diverse and abundant microbial diversity that develops into biofilms, covering the boulders and s ...

Addressing impact of climate change on wind and solar energy infrastructures: the case of India

Yasmine Zakari

In the first part of this thesis, the comparison of two families of CORDEX suggests the improved performance of the latest version in reproducing the local climate. The results indicate increasing future trends for annual wind speeds in the north-west (+0. ...

Patterns and Drivers of Extracellular Enzyme Activity in New Zealand Glacier-Fed Streams

Tom Ian Battin, Hannes Markus Peter, Tyler Joe Kohler, Susheel Bhanu Busi, Stylianos Fodelianakis, Paraskevi Pramateftaki, Matteo Tolosano, Vincent Henri De Staercke, Michail Styllas, Martina Andrea Schön

Glacier-fed streams (GFSs) exhibit near-freezing temperatures, variable flows, and often high turbidities. Currently, the rapid shrinkage of mountain glaciers is altering the delivery of meltwater, solutes, and particulate matter to GFSs, with unknown cons ...

Carbon fluxes and productivity regimes in Alpine streams

Marta Boix Canadell

High-altitude catchments have a major role in the transport of organic matter to streams due to the storage of dissolved organic carbon (DOC) in soils and glacier ice and the subsequent mobilization during the melting processes. Yet, stream function goes b ...

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

Michael Lehning, Wolf Hendrik Huwald

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, curr ...

From the clouds to the ground - Effects of flow-precipitation interactions on snow distribution in complex alpine terrain

Franziska Gerber

Knowledge about the spatial distribution of seasonal snow is essential e.g. to efficiently manage fresh water resources or for hydro-power companies. The large-scale gradient of snow accumulation over mountain ranges is mainly determined by lifting condens ...

Sensitivity of simulated summer monsoonal precipitation in Langtang Valley, Himalaya, to cloud microphysics schemes in WRF

Margaux Caroline Patricia Couttet

A better understanding of regional-scale precipitation patterns in the Himalayan region is required to increase our knowledge of the impacts of climate change on downstream water availability. This study examines the impact of four cloud microphysical sche ...

New lakes in deglaciating high-mountain regions – opportunities and risks

Anton Schleiss

In connection with the ongoing disappearance of glaciers in cold mountains, a great number of new lakes come into existence. The sites and approximate formation time of such potential new lakes can be realistically modelled. This provides an important know ...

A locally calibrated, late glacial Be-10 production rate from a low-latitude, high-altitude site in the Peruvian Andes

Katherine Colby Leonard

Well-dated records of tropical glacier fluctuations are essential for developing hypotheses and testing proposed mechanisms for past climate changes. Since organic material for radiocarbon dating is typically scarce in low-latitude, high-altitude environme ...

Estimating the ice thickness of mountain glaciers with a shape optimization algorithm using surface topography and mass-balance

Marco Picasso, Laurent Michel

We present a shape optimization algorithm to estimate the ice thickness distribution within a two-dimensional, non-sliding mountain glacier, given a transient surface geometry and a mass-balance distribution. The approach is based on the minimization of th ...

Sustainable Land Use in Mountain Regions Under Global Change: Synthesis Across Scales and Disciplines

Alexandre Buttler, François Gillet, Thomas Spiegelberger, Adrienne Grêt-Regamey

Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on th ...

Recent warming in Greenland in a long-term instrumental (1881-2012) climatic context: I. Evaluation of surface air temperature records

Konrad Steffen

We present an updated analysis of monthly means of daily mean, minimum and maximum surface air temperature (SAT) data from Greenland coastal weather stations and from a long-running site on the Greenland ice sheet, and analyse these data for evidence of cl ...
