  • CryoSat-2 interferometric mode calibration and validation: A case study from the Austfonna ice cap, Svalbard 
    Morris, Richard Ashley; Moholdt, Geir; Gray, Laurence; Schuler, Thomas; Eiken, Trond (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Satellite radar altimetry is widely used to measure glacier and ice sheet elevation changes, but can suffer from uncertainties related to geolocation and signal penetration. The unique capabilities of ESA's CryoSat-2 allow ...
  • Gravitational reactivation of a pre-existing post-Caledonian fault system: the deep-seated gravitational slope deformation at Middagstinden, western Norway 
    Schleier, Markus; Hermanns, Reginald Leonhard Manfred; Krieger, Ingvar; Oppikofer, Thierry; Eiken, Trond; Rønning, Jan Steinar; Rohn, Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    The origin of linear features in mountain terrain that form distinct vertical steps is generally not obvious and has been discussed to be related to either tectonic faulting or gravitational slope deformation. A strong ...
  • Interpreting archaeological site-formation processes at a mountain ice patch: A case study from Langfonne, Norway 
    Solli, Brit; Pilø, Lars Holger; Barrett, James H; Eiken, Trond; Finstad, Espen; Grønning, Sunniva; Post-Melbye, Julian R.; Nesje, Atle; Rosvold, Jørgen; Ødegård, Rune Strand (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    In the context of global warming, ice patches are increasingly important foci of high-elevation archaeology. Langfonne in Jotunheimen, central southern Norway, is uniquely suited to provide a window onto site formation ...
  • Lateral thermokarst patterns in permafrost peat plateaus in northern Norway 
    Martin, Leo Celestin Paul; Nitzbon, Jan; Scheer, Johanna; Aas, Kjetil Schanke; Eiken, Trond; Langer, Moritz; Filhol, Simon; Etzelmüller, Bernd; Westermann, Sebastian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Subarctic peatlands underlain by permafrost contain significant amounts of organic carbon. Our ability to quantify the evolution of such permafrost landscapes in numerical models is critical for providing robust predictions ...
  • Structure, emplacement mechanism and magma-flow significance of igneous fingers ? Implications for sill emplacement in sedimentary basins 
    Galland, Olivier; Spacapan, Juan Bautista; Rabbel, Ole; Mair, Karen; Soto, Frederico Gonzalez; Eiken, Trond; Schiuma, Mario; Leanza, Hector Armando (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Field and seismic observations show that numerous sills exhibit lobate morphologies. Each lobe corresponds to a distinct igneous segment exhibiting a finger-like shape, the long axis of which is commonly interpreted as a ...
  • Transitional rock glaciers at sea level in northern Norway 
    Lilleøren, Karianne Staalesen; Etzelmüller, Bernd; Rouyet, Line; Eiken, Trond; Slinde, Gaute Aasen; Hilbich, Christin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Rock glaciers are geomorphological expressions of permafrost. Close to sea level in northernmost Norway, in the subarctic Nordkinn peninsula, we have observed several rock glaciers that appear to be active now or were ...
