    • Pink marine sediments reveal rapid ice melt and Arctic meltwater discharge during Dansgaard-Oeschger warmings 

      Rasmussen, Tine Lander; Thomsen, Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-11-22)
      The climate of the last glaciation was interrupted by numerous abrupt temperature fluctuations, referred to as Greenland interstadials and stadials. During warm interstadials the meridional overturning circulation was active transferring heat to the north, whereas during cold stadials the Nordic Seas were ice-covered and the overturning circulation was disrupted. Meltwater discharge, from ice sheets ...
    • Brine formation in relation to climate changes and ice retreat during the last 15,000 years in Storfjorden, Svalbard, 76–78°N 

      Rasmussen, Tine Lander; Thomsen, Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10-06)
      Storfjorden, Svalbard, is an area of intense brine formation. The brine is cold, dense, rich in oxygen and CO2, and has reduced pH. Storfjorden is unique because it contains well-preserved agglutinated foraminifera dating back to the beginning of the last deglaciation. We have investigated the distribution of calcareous and agglutinated benthic foraminifera, benthic oxygen and carbon isotopes, ...
    • Combining multivariate statistics and the think-aloud protocol to assess Human-Computer Interaction barriers in symptom checkers 

      Marco-Ruiz, Luis; Bønes, Erlend; de la Asuncion Gonzalez, Estela; Gabarron, Elia; Solis, Juan Carlos Aviles; Lee, Eunji; Traver, Vicente; Sato, Keiichi; Bellika, Johan Gustav (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-09)
      Symptom checkers are software tools that allow users to submit a set of symptoms and receive advice related to them in the form of a diagnosis list, health information or triage. The heterogeneity of their potential users and the number of different components in their user interfaces can make testing with end-users unaffordable. We designed and executed a two-phase method to test the respiratory ...
    • Diving behaviour of Atlantic salmon at sea: effects of light regimes and temperature stratification 

      Hedger, Richard David; Rikardsen, Audun H.; Strøm, John Fredrik; Righton, David A.; Thorstad, Eva Bonsak; Næsje, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-04)
      The diving behaviour of adult Atlantic salmon Salmo salar L. post-spawners in the Norwegian and Barents Seas was monitored with pop-up satellite archival tags (PSATs) and data storage tags (DSTs). Salmon from the 3 studied populations showed similar depth use patterns: tagged specimens spent most of their time near the surface (mean of 82% of the time at depths <10 m), with occasional short deep ...
    • Drivers for energy efficiency: an empirical analysis of Norwegian manufacturing firms 

      Solnørdal, Mette Talseth; Thyholdt, Sverre Braathen (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08)
      Manufacturing firms’ ability to innovate and improve their energy efficiency (EE) is a key element in reducing emission of greenhouse gases (GHG) and attain international objectives of climate change mitigation. Despite an urgent need for more knowledge drivers for EE in manufacturing firms, there is still little research on the topic. Taking departure in the EE and environmental innovation literature ...

    • Cold-seep ostracods from the western Svalbard margin: direct palaeo-indicator for methane seepage? 

      Yasuhara, Moriaki; Sztybor, Kamila; Rasmussen, Tine Lander; Okahashi, Hisayo; Sato, Runa; Tanaka, Hayato (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-05)
      Despite their high abundance and diversity, microfossil taxa adapted to a particular chemosynthetic environment have rarely been studied and are therefore poorly known. Here we report on an ostracod species, Rosaliella svalbardensis gen. et sp. nov., from a cold methane seep site at the western Svalbard margin, Fram Strait. The new species shows a distinct morphology, different from other ...
    • Climate warming enhances polar cod recruitment, at least transiently 

      Bouchard, Caroline; Geoffroy, Maxime; LeBlanc, Mathieu; Majewski, Andrew; Gauthier, Stéphane; Walkusz, Wojciech; Reist, James D.; Fortier, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-27)
      Polar cod (Boreogadus saida) is the dominant forage fish in Arctic seas and the main prey of the ringed seal (Pusa hispida), the beluga (Delphinapterus leucas) and several seabird species. Changes in the abundance of polar cod will have cascading effects on arctic marine ecosystems. We tested the hypothesis that an earlier sea ice breakup and warmer sea surface temperatures (SST) in spring-summer ...
    • Visualizing and interpreting surface displacement patterns on unstable slopes using multi-geometry satellite SAR interferometry (2D InSAR) 

      Eriksen, Harald Øverli; Lauknes, Tom Rune; Larsen, Yngvar; Corner, Geoffrey D.; Bergh, Steffen G; Dehls, John; Kierulf, Halfdan Pascal (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-05)
      It is well known that satellite radar interferometry (InSAR) is capable of measuring surface displacement with a typical accuracy on the order of millimeters to centimeters. However, when the true deformation vector differs from the satellite line-of-sight (LOS), the sensitivity decreases and interpretation of InSAR deformationmeasurements becomes challenging. By combining displacement data ...

    • Skarvbergvika i Porsanger. Undersøkelse av to hustufter fra tidlig metalltid og en nyere tids teltring. Porsanger k., Finnmark f. 

      Oppvang, Janne; Kjellman, Erik; Niemi, Anja Roth (Research report; Forskningsrapport, 2018-01-12)
      Høsten 2016 ble det utført en arkeologisk undersøkelse av to tufter i Skarvbergvika, Porsanger k. De to tuftene viste seg å høre til samme periode, første del av tidlig metalltid, og de tolkes som å ha vært i bruk samtidig. Hus 2 tolkes som en boligstruktur og hus 1 som et hus med en spesialfunksjon knyttet til bruk av høy varme. Funnmaterialet besto for det meste av kvarts, med innslag av slipt ...
    • Landsmøtet 1917 og samebevegelsen i nord 

      Bjørklund, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      THE SÁMI NATIONAL ASSEMBLY IN 1917 AND THE SÁMI MOVEMENT IN THE NORTH <br> The Sámi national assembly held in Trondhjem in 1917 is considered to be the very first organized political opposition from the Norwegian Sámi. However, among the 150 persons attending, only three Sámi were from Northern Norway – an area where 90% of the Sámi population lived. The participants were Sámi from the southern parts ...

We investigated that association in the European Prospective Investigation into Cancer and Nutrition cohort. We included 476,160 individuals mostly aged 35-70 years, enrolled in ten countries and followed for 13.9 years on average. Hazard ratios (HR) for developing urothelial cell carcinoma (UCC; 1,802 ...
    • Gauge-origin independent calculations of electric-field-induced second-harmonic generation circular intensity difference using London atomic orbitals 

      Anelli, Marco; Ringholm, Magnus; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      We present the first gauge-origin independent calculations of the circular intensity difference (CID) in electric-field-induced second-harmonic generation (EFISHG), including all contributions up to the electric-quadrupole–magnetic-dipole level. A recursive, open-ended response theory framework in combination with the use of London atomic orbitals allows us to ensure gauge-origin independent results. ...
    • B Vitamins and Hip Fracture: Secondary Analyses and Extended Follow-Up of Two Large Randomized Controlled Trials 

      Garcia Lopez, Maria; Bønaa, Kaare; Ebbing, Marta; Eriksen, Erik Fink; Gjesdal, Clara Gram; Nygård, Ottar; Tell, Grethe S.; Ueland, Per Magne; Meyer, Haakon E (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-28)
      Elevated plasma homocysteine levels are associated with increased risk of fractures in observational studies. However, it is unsettled whether homocysteine-lowering treatment affects fracture risk. The aim of this study was to investigate the effect of an intervention with B vitamins on the risk of hip fracture in a secondary analysis of combined data from two large randomized controlled trials ...
    • Channel interference in multiphoton absorption 

      Alam, MD Mehboob; Beerepoot, Maarten; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-30)
      We extend the theory of channel interference to higher-order multiphoton absorption processes. We derive an explicit expression for channel interference in a three-photon absorption process and propose a general scheme for deriving such expressions for multiphoton absorption processes of any order. Based on this general scheme, we derive and analyze the simplest few-state models for multiphoton ...
    • The creative class: do jobs follow people or do people follow jobs? 

      Østbye, Stein; Moilanen, Mikko; Tervo, Hannu; Westerlund, Olle (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-19)
      Regional adjustment models are applied to explore causal interaction between two types of people distinguished by educational attainment, and two types of jobs: creative class jobs and other jobs. Data used are for labour market regions in Finland, Norway and Sweden from the 2000s. Creative class jobs follow people with high educational attainment (one way causation), but creative class jobs also ...
