Climate and environmental change drives Ixodes ricinus geographical expansion at the northern range margin
Jore, Solveig; Vanwambeke, Sophie O; Viljugrein, Hildegunn; Isaksen, Ketil; Kristoffersen, Anja Bråthen; Woldehiwet, Zerai; Johansen, Bernt; Brun, Edgar; Brun-Hansen, Hege C; Westermann, Sebastian; Larsen, Inger Lise; Ytrehus, Bjørnar; Hofshagen, Merete (Peer reviewed; Journal article, 2014) -
Consequences of permafrost degradation for Arctic infrastructure - Bridging the model gap between regional and engineering scales
Schneider Von Deimling, Thomas; Lee, Hanna; Ingeman-Nielsen, Thomas; Westermann, Sebastian; Romanovsky, Vladimir; Lamoureux, Scott; Walker, Donald A.; Chadburn, Sarah E.; Trochim, Erin; Cai, Lei; Nitzbon, Jan; Jacobi, Stephan; Langer, Moritz (Journal article; Peer reviewed, 2021)Infrastructure built on perennially frozen ice-rich ground relies heavily on thermally stable subsurface conditions. Climate-warming-induced deepening of ground thaw puts such infrastructure at risk of failure. For better ... -
Modeled Microbial Dynamics Explain the Apparent Temperature Sensitivity of Wetland Methane Emissions
Chadburn, Sarah E.; Aalto, Tuula; Aurela, Mika; Baldocchi, Dennis; Biasi, Christina; Boike, Julia; Burke, Eleanor J.; Comyn-platt, Edward; Dolman, A Johannes; Duran-Rojas, Carolina; Fan, Yuanchao; Friborg, Thomas; Gao, Yao; Gedney, Nicola; Göckede, Mathias; Hayman, Garry D.; Holl, David; Hugelius, Gustaf; Kutzbach, Lars; Lee, Hanna; Lohila, Annalea; Parmentier, Frans-Jan W.; Sachs, Torsten; Shurpali, Narasinha J.; Westermann, Sebastian (Peer reviewed; Journal article, 2020)Methane emissions from natural wetlands tend to increase with temperature and therefore may lead to a positive feedback under future climate change. However, their temperature response includes confounding factors and ... -
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 ... -
Projecting circum-Arctic excess-ground-ice melt with a sub-grid representation in the Community Land Model
Cai, Lei; Lee, Hanna; Aas, Kjetil Schanke; Westermann, Sebastian (Journal article; Peer reviewed, 2020)To address the long-standing underrepresentation of the influences of highly variable ground ice content on the trajectory of permafrost conditions simulated in Earth system models under a warming climate, we implement a ... -
Standardized monitoring of permafrost thaw: a user-friendly, multi-parameter protocol
Boike, Julia; Chadburn, Sarah; Martin, Julia; Zwieback, Simon; Althuizen, Inge; Anselm, Norbert; Cai, Lei; Coulombe, Stephanie; Lee, Hanna; Liljedahl, Anne K.; Schneebeli, Martin; Sjoberg, Ylva; Smith, Noah; Smith, Sharon l.; Streletskiy, Dmitry A.; Stuenzi, Simone Maria; Westermann, Sebastian; Wilcox, Evan James (Peer reviewed; Journal article, 2021)Climate change is destabilizing permafrost landscapes, affecting infrastructure, ecosystems and human livelihoods. The rate of permafrost thaw is controlled by surface and subsurface properties and processes, all of which ... -
Thaw processes in ice-rich permafrost landscapes represented with laterally coupled tiles in a land surface model
Aas, Kjetil Schanke; Martin, Leo Celestin Paul; Nitzbon, Jan; Langer, Moritz; Boike, Julia; Lee, Hanna; Berntsen, Terje Koren; Westermann, Sebastian (Peer reviewed; Journal article, 2019)Earth system models (ESMs) are our primary tool for projecting future climate change, but their ability to represent small-scale land surface processes is currently limited. This is especially true for permafrost landscapes ...
