  • 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 / Tidsskriftartikkel / PublishedVersion; 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 ...
  • 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 / Tidsskriftartikkel / PublishedVersion; 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 (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 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 ...
