Constraining frost weathering potential, formation history and subsurface processes of blockfields in Norway and Svalbard
Peter, Maria (Doctoral theses at NTNU;2024:392, Doctoral thesis, 2024)English summary Blockfields cover low-relief mountain summits and low-angle slopes in mountainous periglacial environments, such as in the mountain regions of Scandinavia, Canada, and Russia. They exhibit a unique ... -
A Landform Evolution Model for the Mannen Area in Romsdal Valley, Norway
Hilger, Paula; Hermanns, Reginald; Etzelmüller, Bernd (Chapter, 2020)The Quaternary geology of western Norway’s landscape is the result of glacial and post-glacial sedimentation and erosional processes, a significant sea-level drop and high rock-slope failure activity. All these processes ... -
Multiple rock-slope failures from Mannen in Romsdal Valley, western Norway, revealed from Quaternary geological mapping and 10Be exposure dating
Hilger, Paula; Hermanns, Reginald; Gosse, John C; Jacobs, B; Etzelmüller, Bernd; Krautblatter, Michael (Journal article; Peer reviewed, 2018)Oversteepened valley walls in western Norway have high recurrences of Holocene rock-slope failure activity causing significant risk to communities and infrastructure. Deposits from six to nine catastrophic rock-slope failure ... -
Near-surface temperatures and potential for frost weathering in blockfields in Norway and Svalbard
Peter, Maria; Andersen, Jane Lund; Nixon, Francis Chantel; Etzelmüller, Bernd; Westermann, Sebastian; Fredin, Ola (Peer reviewed; Journal article, 2023)Blockfields remain enigmatic regarding their origin, internal structure, surface processes, and glaciological implications. In Scandinavia, blockfields are found on high-elevation, low-relief mountains (plateaus) across ... -
Permafrost as a first order control on long-term rock-slope deformation in (Sub-)Arctic Norway
Hilger, Paula; Hermanns, Reginald; Czekirda, Justyna; Sæterdal, Kristin Myhra; Gosse, John C.; Etzelmüller, Bernd (Peer reviewed; Journal article, 2021)Assessing initiation of rock-slope deformation and paleo-slip rates of rockslides is important to understand the impact of climate variability - in particular permafrost changes - on rockslide activity. Norway, with 6–6.5% ... -
Permafrost controls the displacement rates of large unstable rock-slopes in subarctic environments
Penna, Ivanna; Magnin, Florence; Nicolet, Pierrick; Etzelmüller, Bernd; Hermanns, Reginald; Böhme, Martina; Kristensen, Lene; Noel, Francois; Bredal, Marie Bergvik; Dehls, John F. (Peer reviewed; Journal article, 2022)Determining the link between permafrost and the displacement rates of large unstable rock-slopes (LURSs) is fundamental for understanding future hazard scenarios and establishing appropriate management strategies. From an ... -
Permafrost distribution in steep rock slopes in Norway: measurements, statistical modelling and implications for geomorphological processes
Magnin, Florence; Etzelmüller, Bernd; Westermann, Sebastian; Isaksen, Ketil; Hilger, Paula; Hermanns, Reginald (Journal article; Peer reviewed, 2019)Permafrost in steep rock slopes has been increasingly studied since the early 2000s in conjunction with a growing number of rock slope failures, which likely resulted from permafrost degradation. In Norway, rock slope ... -
Permafrost in monitored unstable rock slopes in Norway-New insights from temperature and surface velocity measurements, geophysical surveying, and ground temperature modelling
Etzelmüller, Bernd; Czekirda, Justyna; Magnin, Florence; Duvillard, Pierre-Allain; Ravanel, Ludovic; Malet, Emanuelle; Aspaas, Andreas Grøvan; Kristensen, Lene; Skrede, Ingrid; Majala, Gudrun D.; Jacobs, Benjamin; Leinauer, Johannes; Hauck, Christian; Hilbich, Christin; Böhme, Martina; Hermanns, Reginald; Eriksen, Harald Øverli; Lauknes, Tom Rune; Krautblatter, Michael; Westermann, Sebastian (Peer reviewed; Journal article, 2022)The warming and subsequent degradation of mountain permafrost within alpine areas represent an important process influencing the stability of steep slopes and rock faces. The unstable and monitored slopes of Mannen (Møre ...
