Disaggregating the Carbon Exchange of Degrading Permafrost Peatlands Using Bayesian Deep Learning
Pirk, Norbert; Aalstad, Kristoffer; Holmlund, Erik Schytt; Clayer, Francois; de Wit, Heleen; Christiansen, Casper Tai; Althuizen, Inge; Lee, Hanna; Westermann, Sebastian (Journal article; Peer reviewed, 2024)Extensive regions in the permafrost zone are projected to become climatically unsuitable to sustain permafrost peatlands over the next century, suggesting transformations in these landscapes that can leave large amounts ... -
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 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 ... -
Simulating the Thermal Regime and Surface Energy Balance of a Permafrost-Underlain Forest in Mongolia
Zweigel, Robin Benjamin; Dashtseren, Avirmed; Temuujin, Khurelbaatar; Aalstad, Kristoffer; Webster, Clare; Stuenzi, Simone M.; Aas, Kjetil Schanke; Lee, Hanna; Westermann, Sebastian (Peer reviewed; Journal article, 2024)Forests overlap with large parts of the northern hemisphere permafrost area, and representing canopy processes is therefore crucial for simulating thermal and hydrological conditions in these regions. Forests impact ...
