  • Auroral Region Morphology and the Influence of Earth’s Rotation on Geospace Dynamics 

    Decotte, Margot (Doctoral thesis, 2024-06-07)
    Koblingen mellom solvinden, magnetosfæren, og ionosfæren er avgjørende for å forstå verdensrommet og dens påvirkning på Jorden. I de øvre lagene av atmosfæren ved polene, spesielt i området kjent som auroraregionen, møtes ...
  • Wave modulation by strong currents: A study in the Lofoten Maelstrom and surrounding areas 

    Halsne, Trygve (Doctoral thesis, 2024-06-07)
    Bølger og strøm – allestedsnærværende trekk ved havet – er i en konstant tilstand av gjensidig vekselvirkning. Disse prosessene forårsaker sterkt inhomogene sjøtilstander. Samspillet dem imellom regulerer utvekslingsprosesser ...

  • Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis) 

    Ugelvik, Mathias Stølen; Mennerat, Adele; Mæhle, Stig; Dalvin, Sussie Trine (Journal article; Peer reviewed, 2023)
    Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish ...
  • Statistical Embedding: Beyond Principal Components 

    Tjøstheim, Dag Bjarne; Jullum, Martin; Løland, Anders (Journal article; Peer reviewed, 2023)
    There has been an intense recent activity in embedding of very high-dimensional and nonlinear data structures, much of it in the data science and machine learning literature. We survey this activity in four parts. In the ...
  • Seismic interpretation of sill complexes in sedimentary basins: Implications for the sub-sill imaging problem 

    Eide, Christian Haug; Schofield, Nick; Lecomte, Isabelle; Buckley, Simon John; Howell, John Anthony (Journal article; Peer reviewed, 2018)
    Application of 3D-seismic reflection-data to igneous systems in sedimentary basins has led to a revolution in the understanding of mafic sill-complexes. However, there is considerable uncertainty on how geometries and ...
  • Sedimentology and reservoir properties of tabular and erosive offshore transition deposits in wave-dominated, shallow-marine strata: Book cliffs, USA 

    Eide, Christian Haug; Howell, John Anthony; Buckley, Simon John (Journal article; Peer reviewed, 2015)
    Facies models for wave-dominated shorelines include an ‘offshore transition zone’ between shelfal mudstones and nearshore shoreface sandstones. Offshore transition-zone deposits are commonly tabular sandstone beds interbedded ...
  • Shallow and deep groundwater moderate methane dynamics in a high Arctic glacial catchment 

    Kleber, Gabrielle Emma; Magerl, Leonard; Turchyn, Alexandra V.; Redeker, Kelly; Thiele, Stefan; Liira, Martin; Herodes, Koit; Øvreas, Lise; Hodson, Andrew (Journal article; Peer reviewed, 2024)
    Glacial groundwater can mobilize deep-seated methane from beneath glaciers and permafrost in the Arctic, leading to atmospheric emissions of this greenhouse gas. We present a temporal, hydro-chemical dataset of methane-rich ...
