      Even though the coast of western Norway is very windy, the centre of Bergen is rather calm. To gain further understanding of this wind shelter, we study the flow in the complex topography of Bergen during two south-westerly ...
    • Simulations of the Effect of Integrated Metal Nanoparticles on the Optical Absorptance of Perovskite Photovoltaic Solar Cells 

      Egeland-Eriksen, Torbjørn (Master thesis, 2018-09-08)
      The negative effects from the use of fossil fuels that are evident in the ongoing climate change and pollution challenges necessitates a shift from fossil fuels to renewable energy technologies. The most promising of these ...
    • Single CO2 drops in seawater 

      Gangstø, Reidun (Master thesis, 2004)
      To mitigate the increasing atmospheric CO2 level and reduce the subsequent impacts, storage of CO2 is one option that might become necessary. Ocean storage and storage of CO2 under the sea bottom with potential leakage ...
    • Skier stability index - An additional tool for snow avalanche forecasting in Norway? 

      Hunnes, Elise Gloppen (Master thesis, 2018-06-16)
      With more people running to the mountains for skiing backcountry terrain, the need for a good snow avalanche forecast is dire. Todays forecast is based on the weather forecast, snow observations by professional observers ...
    • Skilful decadal-scale prediction of fish habitat and distribution shifts 

      Payne, Mark R.; Danabasoglu, Gokhan; Keenlyside, Noel Sebastian; Matei, Daniela; Miesner, Anna K.; Yang, Shuting; Yeager, Stephen G. (Journal article; Peer reviewed, 2022)
      Many fish and marine organisms are responding to our planet’s changing climate by shifting their distribution. Such shifts can drive international conflicts and are highly problematic for the communities and businesses ...
    • Skilful prediction of cod stocks in the North and Barents Sea a decade in advance 

      Koul, Vimal; Sguotti, Camilla; Årthun, Marius; Brune, Sebastian; Dusterhus, Andre; Bogstad, Bjarte; Ottersen, Geir; Baehr, Johanna; Schrum, Corinna (Journal article; Peer reviewed, 2021)
      Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ...
    • Skillful prediction of Barents Sea ice cover
