The microbial genomics of glacier-fed streams: adaptations to an extreme ecosystem
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 ...
EPFL2024On the importance of the humidity flux for the surface mass balance in the accumulation zone of the Greenland Ice Sheet
It is highly uncertain how the humidity flux between the snow surface and the atmosphere contributes to the surface mass balance (SMB) of the interior Greenland Ice Sheet (GrIS). Due to sparse observations, evaluations of the simulated humidity flux are li ...
Gottingen2024Into the ice: Exploration and data capturing in glacial moulins by a tethered robot
Josephine Anna Eleanor Hughes, Max Mirko Polzin
Glacial moulins (cylindrical meltwater drainage shafts) provide valuable insights into glacier dynamics, but are inaccessible and hazardous environments for humans to study. Exploring them using passive sensor probes has revealed their complex geometry, wh ...
Hoboken2024Understanding snow saltation parameterizations: lessons from theory, experiments and numerical simulations
Michael Lehning, Daniela Brito Melo, Armin Sigmund
Drifting and blowing snow are important features in polar and high mountain regions. They control the surface mass balance in windy conditions and influence sublimation of snow and ice surfaces. Despite their importance, model representations in weather an ...
2024CRYOWRF-Model Evaluation and the Effect of Blowing Snow on the Antarctic Surface Mass Balance
Varun Sharma, Michael Lehning, Franziska Gerber
The surface mass balance (SMB) of large polar ice sheets and of snow and ice surfaces in general are incompletely understood because of the complexity of processes involved. One such process, drifting and blowing snow, has only been considered in a very si ...
AMER GEOPHYSICAL UNION2023Near-bed stratification controls bottom hypoxia in ice-covered alpine lakes
Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Camille Roland Marie Minaudo, Janine Rüegg, Tomy Doda, Nicolas Thomas Georges Escoffier, Hannah Elisa Chmiel, Pascal Perolo
In ice-covered lakes, near-bottom oxygen concentration decreases for most of the wintertime, sometimes down to the point that bottom waters become hypoxic. Studies insofar have reached divergent conclusions on whether climate change limits or reinforces th ...
WILEY2023Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...
2023Reproducibility Dataset for CRYOWRF v1.0
Varun Sharma, Michael Lehning, Franziska Gerber
This repository contains data required for reproducibility of the results to be published in the associated manuscript. Apart from reproducibility, the attached datasets also serve as templates for new users to adopt CRYOWRF in their research. The datasets ...
2023Blue ice in Antarctica: The gateway to travel in time and space
Devis Tuia, Benjamin Alexander Kellenberger, Marc Conrad Russwurm, Veronica Tollenaar
Antarctica has unique areas that expose blue ice, which contrast to most of the continent (~98%) that is covered by snow. Some of these blue ice areas (BIAs) contain meteorite concentrations and (very) old ice, making them very valuable for understanding o ...
GFZ German Research Centre for Geosciences2023Assessing sublimation during snow transport and sublimation effects on the isotopic composition of water vapor
Sublimation influences the water storage in snow covers and glaciers, which is important for water use and projections of the sea level rise. Yet, it is challenging to quantify sublimation for large areas or in conditions of snow transport. In-situ measure ...
