• Loss of sea ice during winter north of Svalbard 

      Onarheim, Ingrid Husøy; Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Frank (Peer reviewed; Journal article, 2014-06-05)
      Sea ice loss in the Arctic Ocean has up to now been strongest during summer. In contrast, the sea ice concentration north of Svalbard has experienced a larger decline during winter since 1979. The trend in winter ice area ...
    • Regional, seasonal, and predictable Arctic sea ice change 

      Onarheim, Ingrid Husøy (Doctoral thesis, 2017-12-07)
      The loss of Arctic sea ice is one of the most prominent and best quantified indicators of ongoing global climate change. Satellite passive microwave observations since 1979 indicate significant negative sea ice extent ...
    • 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 ...
    • 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 ...
