How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

PhD student with strong interest in peri_para_glacial landscape and mountain geomorphology. Specific interest in spatial (raster) data, GIS and remote sensing. Euphoric about the outdoors, nature conservation and fieldwork.
Climate change has repeatedly been framed as the defining issue of the Anthropocene and with the Arctic changing at unpreceded speed need is high for a profound understanding of the Northern Swedish landscape. Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. Their location, orientation and geomorphometry c...
Current climate change in the Arctic is unprecedented in the instrumental record, with profound consequences for the environment and landscape. In Arctic Sweden, aeolian sand dunes have been impacted by climatic changes since their initial formation after the retreat of the last glacial ice sheet. Dune type, location and orientation can therefore b...
In high mountain regions, climatic conditions are a key factor in the development of permafrost. Next to altitudinal impact, topo-climatic and subsurface conditions further influence the occurrence of permafrost. As a result, mountain regions show extremely irregular periglacial distribution patterns which cannot be simply estimated by lapse rates...
Extensive areas in mountain regions are under permafrost conditions with periglacial processes in the arid Andes of Argentina being mostly associated with high mountain permafrost. The most visible expression of creeping mountain permafrost within the periglacial altitudinal belt (between 35º and 27ºS), is the occurrence of rock glaciers. Beside sn...
In the last three years, an initiative has grown in the geoscientific community to create diamond open access journals, which are free to access, free to read, and free to publish, for all. This started with Volcanica, and now, Seismica, Tektonika and Sedimentologika have launched their own community-led, field-specific journals. One key component...
The Andean cryosphere hosts major freshwater sources for proximal and distal inland lowlands in river catchments especially in arid and semi arid regions, providing runoff and groundwater recharge. As many watersheds in the semiarid Andes of Argentina are not at all glacierized (ice glacier) but generate numerous creeks and small rivers, periglacia...
The main objective of this DFG funded project is to study the spatial distribution, geomorphic characteristics and hydrological significance of Andean mountain permafrost in taluses (including protalus ramparts) and blockslopes. Findings from our previous DFG project on rock glaciers (PermArg) will be integrated and extended through mapping, statistical modelling, geophysical surveys (incl. four-phase modelling) and continuous discharge measurements at six different gauging stations. The Andean cryosphere is an important hydrological reservoir that provides runoff and groundwater recharge through glacier melt, precipitation, snowmelt (including perennial snowfields), and water releases from the active layer of extensive permafrost affected landforms. We expect that a significant part of the (seasonally) thawing active layer of these periglacial landforms (taluses, blockslopes, rock glaciers) contribute to the overall discharge and groundwater recharge. The quantitative estimation of this non-glacial contribution to the overall discharge will enrich our knowledge on the hydrological importance of Andean permafrost.
