    • 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 

      Onarheim, Ingrid Husøy; Eldevik, Tor; Årthun, Marius; Ingvaldsen, Randi; Smedsrud, Lars Henrik (Peer reviewed; Journal article, 2015-07-08)
      A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ...

    • Skillful prediction of northern climate provided by the ocean 

      Årthun, Marius; Eldevik, Tor; Viste, Ellen; Drange, Helge; Furevik, Tore; Johnson, Helen L.; Keenlyside, Noel (Peer reviewed; Journal article, 2017-06-20)
      It is commonly understood that a potential for skillful climate prediction resides in the ocean. It nevertheless remains unresolved to what extent variable ocean heat is imprinted on the atmosphere to realize its predictive ...

    • Spatial Patterns, Mechanisms, and Predictability of Barents Sea Ice Change 

      Efstathiou, Evangelia; Eldevik, Tor; Årthun, Marius; Lind, Sigrid (Journal article; Peer reviewed, 2022)
      Recent Arctic winter sea ice loss has been most pronounced in the Barents Sea. Here we explore the spatial structure of Barents Sea ice change as observed over the last 40 years. The dominant mode of winter sea ice ...

    • Still Arctic? — The changing Barents Sea 

      Gerland, Sebastian; Ingvaldsen, Randi Brunvær; Reigstad, Marit; Sundfjord, Arild; Bogstad, Bjarte; Chierici, Melissa; Hop, Haakon; Renaud, Paul Eric; Smedsrud, Lars Henrik; Stige, Leif Christian; Årthun, Marius; Berge, Jørgen; Bluhm, Bodil Annikki Ulla Barbro; Borgå, Katrine; Bratbak, Gunnar; Divine, Dmitry V; Eldevik, Tor; Eriksen, Elena; Fer, Ilker; Fransson, Agneta; Gradinger, Rolf Rudolf; Granskog, Mats A.; Haug, Tore; Husum, Katrine; Johnsen, Geir; Jonassen, Marius Opsanger; Jørgensen, Lis Lindal; Kristiansen, Svein; Larsen, Aud; Lien, Vidar Surén; Lind, Sigrid; Lindstrøm, Ulf Ove; Mauritzen, Cecilie; Melsom, Arne; Mernild, Sebastian H.; Müller, Malte; Nilsen, Frank; Primicerio, Raul; Søreide, Janne; van der Meeren, Gro Ingleid; Wassmann, Paul (Journal article; Peer reviewed, 2023)
      The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ...

    • Surface-Forced Variability in the Nordic Seas Overturning Circulation and Overflows 

      Årthun, Marius (Journal article; Peer reviewed, 2023)
      Water mass transformation in the Nordic Seas and the associated overflow of dense waters across the Greenland-Scotland Ridge (GSR) acts to maintain the lower limb of the Atlantic meridional overturning circulation. Here, ...

    • Time Scales and Sources of European Temperature Variability 

      Årthun, Marius; Kolstad, Erik Wilhelm; Eldevik, Tor; Keenlyside, Noel (Peer reviewed; Journal article, 2018-04)
      Skillful predictions of continental climate would be of great practical benefit for society and stakeholders. It nevertheless remains fundamentally unresolved to what extent climate is predictable, for what features, at ...

    • Toward an ice-free Barents Sea 

      Onarheim, Ingrid Husøy; Årthun, Marius (Peer reviewed; Journal article, 2017)
      Arctic winter sea ice loss is most pronounced in the Barents Sea. Here we combine observations since 1850 with climate model simulations to examine the recent record low winter Barents Sea ice extent. We find that the ...

    • Variability along the Atlantic water pathway in the forced Norwegian Earth System Model 

      Langehaug, Helene R.; Sandø, Anne Britt; Årthun, Marius; Ilicak, Mehmet (Peer reviewed; Journal article, 2018-03-27)
      The growing attention on mechanisms that can provide predictability on interannual-to-decadal time scales, makes it necessary to identify how well climate models represent such mechanisms. In this study we use a high (0.25° ...

    • Variable Nordic Seas Inflow Linked to Shifts in North Atlantic Circulation 

      Asbjørnsen, Helene; Johnson, Helen L.; Årthun, Marius (Journal article; Peer reviewed, 2021)
      The inflow across the Iceland-Scotland Ridge determines the amount of heat supplied to the Nordic Seas from the subpolar North Atlantic (SPNA). Consequently, variable inflow properties and volume transport at the ridge ...

    • Water mass transformations and air-sea exchange in the Barents Sea 

      Årthun, Marius (Doctoral thesis, 2011-09-22)
      Water mass transformation processes in the Barents Sea and their interannual to decadal variability are studied using a regional coupled ice-ocean model and observational data. Long-term data allows for assessment of ...
